Activar Puerto de archives para IDOCS

Para esto nos podemos basar en la help sap

IDoc Inbound Processing

Use

IDocs (intermediate documents) have been developed for the exchange of messages between different systems. Providing a standard interface with the SAP system, this technique can also be used to transfer data.

For more information, choose IDoc Interface in transaction WEDI. . See also: Starting IDoc Generation

Prerequisites

To be able to use IDoc inbound processing, you have to define settings and perform preparatory tasks. These tasks are grouped on the initial screen of the LSM Workbench under Settings → IDoc Inbound Processing.

To use IDoc inbound processing, you must first perform the following steps: 1. Define or select a file port for transporting the file. Optionally, you can also create a tRFC port.

See Creating Ports

2. The partner type has to be defined or selected. See Partner Types

3. The partner number has to be defined or selected. See Partner Numbers

4. IDoc inbound processing must be activated, and the workflow customizing must be checked. Both of these tasks are performed once in each system.

(3)

Creating Ports

Use

A port has to be available for a transfer of data from a legacy system to the SAP System by means of IDocs. As well as the file port, you can also specify a tRFC port. For data conversion, you can decide whether a file should be created or whether the data should be passed to inbound processing by "packages" directly.

See Starting IDoc Generation Prerequisites

You have chosen Settings → IDoc inbound processing on the LSMW initial screen, and

the IDoc inbound processing: Preparations screen is displayed. Procedure

We recommend to maintain the following entries: ...

Choose Maintain ports.

The WF-EDI: Port Definition screen appears. Activate the change mode.

Position the cursor on File and choose Create.

Fill in the given fields. Recommendation: Port:

LSMW

Description: Legacy System Migration Workbench Version: IDoc record types: SAP Release 4.x

If you additionally want to create the transactional RFC port:

Position the cursor on Transactional RFC and choose Create. Fill in the given fields.

Save your entries.

Choose F3 or Back to return to the IDoc inbound processing: Preparations screen. Si exportas un LSMW de alguno existente debes de refrescar el proceso de creacion para que actualice los perfiles

Result

The partner port has been created. More Information

Partner Types

Use

You must select a partner type when you transfer data from an external system or legacy system to an SAP system in IDocs. For the LSMW, we recommend that you use the partner type US.

Prerequisites

You have chosen Settings → IDoc Inbound Processing on the LSMW initial screen, and

you are on the screen IDoc Inbound Processing: Preparatory Measures. Procedure

Enter US as the partner type. To do this, proceed as follows:

1. Choose Maintain Partner Types. 2. Activate the change mode. A table is displayed.

(6)

4. Fill in the fields. Recommended values:

Partner type: US

Report name: /SAPDMC/SAP_LSMW_PARTNERTYPES

Form routine: READ_USER

Short text: <any>

5. Save your data and choose F3 or Back to return to the screen IDoc Inbound

Processing: Preparatory Measures.

See also: Transaction WE20 → Maintain Partner Profiles Result

The partner type has been created.

Partner Numbers

Use

You must select a partner number when you transfer data from an external system or legacy system to an SAP system in IDocs.

Prerequisites

(7)

Procedure

Enter LSMW as partner number. Or:

...

1. Choose Maintain partner numbers. The Partner Profiles screen appears. 2. Choose Create.

3. Fill in the given fields. Recommendation:

Partner number:

LSMW Partner type: US

Partner status: A (active)

Type: US

Language: EN or DE

ID: Your user ID

4. Save your data and choose F3 or Back to return to the IDoc inbound processing:

Preparations screen.

Checking the Workflow Customizing

Use

Workflow Customizing defines the requirements for using IDoc inbound processing. Prerequisites

the IDoc inbound processing: Preparations screen is displayed. Procedure

...

1. Choose Workflow customizing.

The Workflow Customizing screen appears.

2. Choose Perform Automatic Workflow Customizing. The auto customizing log for the runtime system is displayed. 3. Check the entries.

The following entries of the workflow runtime system must have a green checkmark assigned to them:

– Maintain System Administrator for Workflow.

– Configure RFC Destination.

– Classify Decision Task as General.

– Activate Send to Objects and HR Objects.

Maintain Object Attributes

(10)

Se da click al botón y se selecciona la opción Business Object Method (BAPI)

En el campo Business Object se selecciona el objeto, para este ejemplo utilizare BUS1001006, para crear material estandar

Una vez seleccionado, en el campo Method, se selecciona la BAPI que se desea utilizar

(11)

Y se puede grabar el primer paso.

Maintain Source Structures

(12)

Se da click al boton de modificar y luego al de crear. Cuando se genera una

estructura para una grabación en batch, se crea una estructura única; para el caso de las bapis se deben crear mas estructuras; esto depende de las estructuras de import que maneja la BAPI.

Para este ejemplo se manejan dos estructuras. Se crea la estructura de cabecera

(13)

Maintain Source Fields

Se deben indicar los campos del layout; lo que diferencia este proceso con BAPI al del BATCH es que se debe generar un indicador para la cabecera y las posiciones en la BAPI.

(14)

Indicador para cabecera

Indicador para posición

Debido a que se generan dos estructuras, el layout contempla dos líneas para cada dato maestro que se desea generar.

(15)

BAPI.xlsx

Maintain Structure Relations

Se da click a la opción Maintain Structure Relations

Se da click al botón de modificar y se asignan las estrucutras de origen con las estructuras de la BAPI.

(16)

Maintain Field Mapping and Conversion Rules

(17)

Se debe considerar que algunas de las bapis tienen estructuras de confirmación, ejemplo:

Los datos capturados en la bapi E1BP_MARC deben ser confirmados con una X en al estructura E1BP_MARCX, de lo contrario no se actualizaran.

En este punto es imprescindible entrar a la transacción SE37 para validar el trabajo estándar de la BAPI, una vez conociendo su funcionamiento, es más fácil generar su LSMW

Specify Files

(18)

Se debe tener cuidado en seleccionar la opción de datos para multiples estructuras de origen

Este es el archivo que se cargara en el ejemplo

BAPI.txt

Assign Files

Aquí se asigna el archivo dos veces, una por cada estructura, solo se puede hacer si existen 2 estructuras de origen y si se selecciono la opción indicada en el punto 8.

Read Data

Se ejecuta la opción de manera normal

(21)

Cada línea verde representa un documento generado y abajo las estructuras que se ocupan para el envío de datos.

Start IDoc Generation

(22)

El proceso genera un IDOC por cada registro que se va crear

Start IDoc Processing

(24)

Create IDoc Overview

Se ejecuta la opción de manera normal; esta opción permite visualizar los mensajes de los IDOCS ejecutados

(25)

Recomendaciones

Buscar la bapi y ejecutarla en la transacción se37, el objetivo es conocerla y saber la totalidad de campos0020a llenar y la estructura de labapi.
