Materials for which this remaining life is not maintained are searched for with stock removal strategy "FIFO".
Activities
1. You have to decide whether you want to use this stock removal strategy.
2. Activate the shelf life expiration date management for each warehouse number.
The shelf life expiration date management must be activated at warehouse number level. In the application, this activation causes that the shelf life expiration date is a required entry during stock placements, depending on the material and movement type. In some analyses, the shelf life expiration date of materials managed according to shelf life expiration date is displayed instead of the GR date.
Activate the shelf life expiration date management.
3. Activate the stock removal strategy
Activate the stock removal strategy expiration date in the stock removal control for the relevant storage type.
Further notes
If you are using the stock removal strategy "Strict FIFO principle", please refer to the section "Define Strict FIFO Principle" strategy for more information on the
"Shelf Life Expiration Date".
Activities
Activities
In this unit, you set the following activities in the Warehouse Management system:
• Transfers
In this section, you set the configuration for the transfer of goods.
This includes the following:
Movements and stock records in the Warehouse Management System contain a reference to the originating document.
The requirement category describes the origin type (for example, goods receipt for a purchase order, and goods issue for the cost center). The requirement tracking number describes the origin itself (for example, the purchase order number, the cost center).
Actions
Create the requirement types for each warehouse number.
Define Shipment Types Define Shipment Types
In the Warehouse Management system, there are two types of transfers (movements):
• Movements that are also important for Materials Management (for example, stock placements and stock removals)
• Movements that only concern the warehouse
(stock transfers within a warehouse, for example).
The transfer type is a suitable tool for reports (for example, all stock placements into a storage type, all stock removals from a storage type, and so on).
Note
The transfer type is not used in system control functions.
Standard Delivery
In the SAP standard delivery, all the relevant transfer types are preset.
SAP Recommendation
SAP recommends keeping the transfer types delivered with the standard system. You can add to these transfer types as required.
Actions
Define the transfer types for each warehouse number.
Define Movement Types
The system processes Inventory Management movements (for example, goods receipt for a purchase order or goods issue to a cost center) using movement types. If the SAP system determines that a movement is relevant for Warehouse Management, it assigns a WM movement type to this movement via a table.
The movement type for the Warehouse Management system provides the information required for stock placements and stock removals:
Interim storage type
Coordinate of the interim storage bin
predefined coordinate
dynamic coordinate
fixed bin coordinate
Control indicator for processing, confirming and printing transfer orders
Indicator for storage type search.For information on the links between the IM and the WM movement types and how to change them, see the section Movement Types for Interim Storage Bins.
Standard settings
In the SAP standard system, all the relevant movement types are preset.
Recommendation
SAP recommends keeping the movement types delivered with the standard system.
Activities
1. Before you create movement types for a new warehouse number:
start with the configuration for the printer control
delete the print codes
then maintain the print codes when you configure the printer control
2. Create the movement types for each warehouse number using the copy function.
3. Define your own company-individual settings (for example, for the interim storage types) in the detail screen.
Define Stock Transfers and Replenishment Control
Define Stock Transfers and Replenishment Control
Using a posting change, you can change the material identification of stocks. A posting change affects at least one of the following items:
material number
plant
stock category
special stock
A stock transfer is involved if a quant is moved physically from its storage bin.
Posting changes and stock transfers always take place within a warehouse number.
Standard settings
For stock transfers and posting changes, the movement types in the series "3nn" are at your disposal.
For internal warehouse replenishment, use the WM movement type "319". You can use this movement type as a copy sample for creating your own movement type.
Activities
3. If you want to use the functionality "Replenishment for fixed bin warehouse"
(using the report RLLNACH1), you must define the storage types for which replenishment is to be used.
Assign the appropriate replenishment type to the respective storage types.
Confirmation Confirmation
In this section, you configure the system settings for handling differences and for confirming transfer orders.
Handling Differences
The system posts differences that you find in the warehouse into a specific difference storage type (for example, 999) whenever you
• Confirm a transfer order with differences.
• Perform a manual stock transfer to the difference storage type (for example, 999).
• Perform automatic stock transfer to the difference storage type (for example, 999) after an inventory with quantity differences.
In the WM system, you can classify differences according to cause (for example, breakage, theft).
Using the difference indicator, you determine the storage type and the storage bin to which the differences are posted.
For each difference indicator, you can save the percentage value for the deviation allowed, that is, starting from which the dialog box is to appear. Suppressing the dialog box is appropriate for stock picks that cannot be done to the exact amount and where the difference is cleared against the stock in the source bin.
Example
A warehouse worker guesses a 3 kilogram pick for a particular material and determines the actual weight further away from the bin. In this case, each pick is confirmed with a difference. It would be appropriate to have the dialog box suppressed so as to save this extra step.
Confirmation Control
One important aspect of confirmation of transfer orders is the setting of the confirmation requirement. This requirement means additional work for the user, but it also affords a high level of stock and information security.
The decision as to whether a transfer order item requires confirmation and whether it is confirmed immediately depends on the parameters you set for your movement types and your storage types.
• At the warehouse number level you define:
o whether there is to be separate confirmation of pick and transfer
o whether putaways to this storage type require confirmation o whether picks from this storage type require confirmation
o whether a zero stock check is to take place for a bin that becomes empty through the pick
o whether the destination storage bin can be changed during confirmation
• At the movement type level you define:
o whether transfer orders with this movement type can be confirmed immediately
o whether the confirmation requirement is to be proposed during transfer order generation
o whether single-step confirmation is to be applied although two-step confirmation is set for the source and destination storage types
o through which screen the transfer orders are to be confirmed.
Confirmation Requirement
As soon as one of the above parameters calls for a confirmation requirement for a transfer order item, the item must be confirmed.
Immediate confirmation of a transfer order item only works out if
• the respective movement type does not disallow this
• if the storage type from which the materials are picked is not subject to pick confirmation
• if the storage type into which the materials are put away does not have a putaway confirmation requirement.
Two-Step Confirmation
For two-step confirmation, both storage types involved in the transfer order must be subject to confirmation.
At the warehouse number level, you define whether transfer orders or TO items are to be confirmed in two separate steps.
During the confirmation of the first step, you confirm the pick process from the source storage bin. The source storage bin and the quant are automatically updated. In the quant of the destination storage bin, only the open transfer quantity is updated at this point.
During the confirmation of the second step, you confirm both the transfer process and also the receipt of the material at the destination storage bin. Here the source storage bin and its
quant are no longer updated, but only the destination storage bin and the quant stored there.
SAP Recommendation
SAP recommends working with the stock placement and stock removal confirmation functions. The confirmation procedure is recommended for the following reasons:
• Stock in a storage bin should only be available after the actual putaway has been confirmed.
• Storage bins should only be released for further putaways after the goods putaway in the destination bin has been confirmed.
• A storage bin that is going to be emptied by a pending stock pick should already be filled with a putaway before it is really emptied.
• The posting of differences should be executed during the actual confirmation, and not by means of a separate transfer order.
Include the confirmation process in your organizational procedures.
You can use the bar code for confirming transfer orders. This makes your work much easier.
Activities
1. Decide whether you want to confirm the transfer orders created in the SAP system using the confirmation procedure.
2. Maintain the difference indicator for differences in TO confirmation.
3. Maintain the indicator "Confirmation control/Warehouse number".
4. Maintain the indicator "Confirmation control/Storage type".
5. Maintain the indicator "Confirmation control/Movement type".
Define Print Control
In this section, you set the configuration data for print control.
Using the print control function, for example, you can define
• Which documents (that is, for transfer orders) are to be printed for goods movements.
• How these documents are to be printed (that is, which forms are to be used, how many copies are to be printed).
• On which printer a document is to be printed automatically.
Using the print control functions, you have flexible control of the printing activities in your warehouse. This flexibility, however, means that setting the parameters is a complex task.
For this reason, we recommend that you take a look at the entire print control functions first, and then analyze the "print situation" in your warehouse.
The number and type of settings you need for your print control depends on whether you are using the Storage Unit Management component. If you are not using this component, you only need to set the "standard" print control functions. However, if you are using Storage Unit Management, you need to set both the "standard" print control functions as well as the functions for storage units.
In this section, we describe the "standard" print control functions. These control the printing
of transfer order slips.
The print control for printing specific slips for storage units is described in the chapter Define print control for warehouses with Storage Unit Management.
You need the following settings for the "standard" print control function:
• Spool Indicator
Slips are always printed within the SAP system using the Spool function. For each printout, certain data needs to be passed on to the Spool file. Typical examples of such data are:
o Number of copies to be printed
o Dataset name of the printout within the Spool system o "Print immediately"
o "Delete after print"
Using the Spool indicator, you define the most appropriate combinations of the
individual parameters you want to use.
In the following settings (for example, the settings for the print code), you do not need to specify these parameters each time. You only enter the spool indicator as a type of abbreviation.
• Printer Pool / Labels
In the printer pool for labels, you can define a dependent label printer for each printer. In this way, for example, labels can be printed in parallel on special paper while transfer order documents are being printed.
• Sort Profile / Multiple Processing
The sort profile sets the sequence of the transfer order items for printing. As of Release 4.1A, this only applies to printing in multiple processing, since during
"standard" TO processing the sorting is set already when the TO is created.
Furthermore, you can decide during multiple processing printing whether there should be a control break, that is, whether printing should continue on a new page if the field content changes.
• Print code
The print code defines the following information for printing transfer orders:
o Form that is used for printing
o Sort sequence (via sort pool) in which the individual items of a transfer order are to be printed. The sort pool is now called up through the multiple processing run.
o Spool indicator (see above)
o Reading shipping data. With this function you can have additional information for picking orders called up, for example, the address of the ship-to party or serial numbers already assigned to the delivery items.
o Reading production data. Here reservations for staging materials for production are read. (Both switches for reading data should be inactivated for time-critical printing.)
o Label form, label spool indicator, and the definition as to how the number of labels is to be determined for each TO item.
The following text explains how you can assign a print code to each movement type in the Warehouse Management system. A transfer order is always assigned to a movement type. In this way, the print code determines the general print parameters for the transfer order.
• Assignment of Print Code / Movement Type
You can define different printers and spool codes for various goods movements (source storage type - destination storage type). Also, you can suppress the printing of transfer orders, if required.
There are also parameters (print code, form) that you can define both in the configuration "Printer-Movement" as well as in the print code settings.
During the automatic determination of the print parameters, the system proceeds as
determines the general print parameters through the print code assigned to the movement type. Afterwards, it checks the movement-specific print parameters. If one of these parameters (for example, for the form) is also defined in the print code, the system will use the movement-specific parameter.
It is possible to override the definitions for label printing in the print code, depending on the warehouse movement.
You can also store an additional form for a combined picking list with the spool code and the printer in order to print a combined document in parallel to single printing for each TO item. This is only possible as an accompaniment to non-combined-printouts (indicator for combined printing in the print code) and is otherwise ignored.
• Assignment Printer - Picking Area
It can be useful to select a printer near the picking area for printing picking orders.
Again you are faced with the question: How does the system proceed with automatic printer determination, since it is possible to define a standard printer both in the configuration for "Printer-Movement" as well as in the configurations "Printer - Storage Type", "Printer - Picking Area", and in the user master of each user?
First the system checks whether a printer is set in the configuration "Printer-Movement". If so, the printer determination is complete at this point.
If not, the system uses the parameter "PriSrcTyp" defined in the configuration
"Printer-Movement" to decide how it will proceed.
If the parameter is set here, the system checks if a printer is defined in the setting
"Printer Picking Area" and then proposes this printer.
If the system finds no printer, it searches in the setting "Printer - Storage Type" and uses this, if a printer is set.
If the system cannot find a printer using the methods described above, it selects the printer defined in the user master of the user currently logged on.
If no printer is defined here, the system automatically proposes LP01. This writes the data to the spool file.
• Assignment Printer - Storage Type
Here you can store one printer per storage type, in accordance with the printer determination logic described above.
• Assignment Print Code - Movement Type
A print code is assigned to each movement type. As described above, the general print information is determined by this assignment.
• Assignment Print Program - Warehouse Number
You must assign a print program to each warehouse number. The name of the standard program is RLVSDR40.
• Print Control Multiple Processing
A print report is assigned to each warehouse number for printing a combined transfer order. You can also configure the following:
o the print code
o the printer o the print time
• The print layout is set using forms.
Standard settings
All relevant print control tables are defined in warehouse number 001.
The following print programs are available:
• RLVSDR40 (general print program)
• RLKOMM40 (multiple processing) Recommendation
Only use your own print programs if your print requirements are not met by the user exits in the standard system. If you wish to extend the functionality of the program RLVSDR40, use the user exit MWMD0001 to develop them. If you wish to extend the functionality of the program RLKOMM40, use the user exit MWMD0002. For further information on enhancements through the user exit, refer to the chapter Develop extensions.
Information on how to adapt forms in Warehouse Management is provided in the chapter Develop forms.

2. Create the dependent printers for label printing.
3. Define the sort profile for multiple processing.
4. Create the print codes for each warehouse number.
5. Assign the printers to the individual movements.
6. Assign the printers to the picking areas.
7. Assign the printers to the storage types.
8. Assign the print codes to the movement types.
9. Assign the print reports to the warehouse numbers.
10. Assign the print control to the multiple processing runs.
11. Using the analysis program, check whether the settings comply with your needs.
Physical Inventory
Physical Inventory
In this menu option, you configure the following system settings:
• Default values
• Types per storage type
• Differences
• Number ranges
Unlike the material-related physical inventory in the Inventory Management (IM) system, the Warehouse Management system supports inventory procedures based on the storage bin.
Define Default Values Define Default Values
In this menu option you define:
• which data should be printed out on the system inventory record
• how the entry screen for the inventory count should be set up Actions
Maintain the default values for each storage type.
Define Types per Storage Type Define Types per Storage Type
The Warehouse Management system (WM) supports the following inventory procedures:
• Annual inventory(ST)
Counting the material quantity in the storage bins at a fixed inventory date.
• Continuous inventory (PZ)
Counting a certain number of storage bins on any day in the fiscal year.
• Continuous inventory based on stock placement
When a bin is occupied for the first time in the fiscal year, the system registers that inventory has been taken for that bin. You can only use this inventory procedure under certain conditions and must always check with the company auditor first.
• Continuous inventory based on zero stock check
• Continuous inventory based on zero stock check
