Definitions 1

Business Object (BO):

Smallest unit of an object model with exclusively unstructured attributes. Each BO is assigned a unique name. A BO can be either an access object, a dependent object or a query object.

BO instance:

Instance of a BO that is uniquely identified by the name of the BO and an identifier (ID).

Relation:

A relationship between two BOs that is assigned a unique,

cross-component name. The relation is assigned “a cardinality value” for each BO. The navigation direction is a characteristic of the relation.

Object model:

(18)

Definitions 2

Access Object:

An access object is a special type of BO, whose ID can be used to determine both the attributes of the access object itself and those of its dependent objects.

Dependent Object:

A dependent object is a special type of BO, whose attributes cannot be determined solely from the ID of this BO, but instead, only or together with the ID of the superior access object.

Root object:

A root object is a special element within a group of objects that are linked to one another in a hierarchy structure via aggregations. The root object is the only object within this structure that is assigned as a superior object to all other objects. Each root object is also an access object.

Search-Object:

A query object is a special type of BO whose attributes are the parameters of a search request.

Dynamic Search-Object:

A dynamic query object is a type of BO whose attributes are the parameters of a search request. It is possible to create select options for these parameters.

Search Result Object:

The result object of a search request is an associated access object at the uppermost level of the hierarchy.

Transaction: SPRO ->IMG -> Customer Relationship Management -> CRM Cross-Application Components -> Generic Interaction Layer/Object Layer -> Basic Settings

(20)

Definitions 3

Component:

A component is an ABAP OO class which implements the

component interface. It exposes a set of CRM business objects to

the Generic IL, which form an aggregation hierarchy. Each

component must have a unique root object.

Component Set

A component set is a collection of components that build a

business context for a specific application that uses the business

layer as its framework.

BOL Services

„

Buffering service

any data is only read once until it is changed

all changes are buffered and will be send together

automatic buffer synchronization in almost all cases

„

Transaction service

objects may be saved individually or all together

all changed/created object will be saved or reverted

„

Query services

– New Query service for dynamic searches with CRM 2006

„

Simple sorting and filtering on object lists (collections)

„

Attribute properties

for each attribute of an entity a property is available

(23)

©SAP AG 2007, SAP Skills 2007 Conference / F4 / 23

BOL Transaction Model

„

The transactional behavior of BOL objects is modeled in the

transaction context. A transaction context is created:

when an entity is locked, or

if it is requested, but not yet existing.

„

A transaction context can have several kinds of granularity

The smallest granularity of a transaction context is a root entity

instance

The biggest granularity are all changed/created entity instances

The custom transaction context allows any granularity in between

„

Each transaction context has a defined life cycle. Once it was

created it ends with either

Saving all covered entities, or

(24)

BOL Transaction Model 2

„

Data is always saved synchronously. Either within the dialog

process (local update), or, if this is not possible, with COMMIT

WORK and WAIT

„

After saving the BOL buffer is invalidated and refreshed on the

next access

(25)

BOL Services –

Message Service

Message Service

„ There is one message protocol/container per root object instance and the message container manager handles them all. Additionally one global message container exists were all non-business object (BO) instance-related messages should go to.

New Component Concept

A Component...

„ …is a meaningful bundle of view sets, views and custom controllers

„ …is a self-contained reusable unit

black box approach:

- Own runtime repository

- Exposes clear interface to the outside: - windows (as interface views) - public context nodes

„ … can have multiple instances at runtime

„ … technically is mapped to a BSP application

thus it is the organizational unit in the development logistic that is assigned to a package

With the new CRM UI Framework a new concept is introduced valid for all Applications which are based on this Framework.

(33)

©SAP AG 2007, SAP Skills 2007 Conference / F4 / 33

New Window Concept

A Window...

„ … is part of a component and defines a root for a hierarchy of view sets and views in the runtime repository

A viewsetor view can only be part of exactly

onewindow (still no direct reuse of views)

Navigation between views is only possible

withina single window

„ …. mediates between the embedding and the embedded component during runtime

has the character of a view to the inside (window aspect)

has the character of a simple view to the outside (interface view aspect)

Each component must have one or more windows which are hosting the views

Runtime Repository

Each component has its own runtime repository file

„ It acts a a catalogue containing

views, viewsets and the composition of views within viewsets

Navigational links (with target and source view)

Inbound and outbound plugs definitions

etc.

„ Technically stored as .xml file

CRM Web Client: View Details

Each configurable view is based on: „ A page type related configuration tag

„ Structural setters/getters

Specific implementations possible via: „ Dedicated setter/getter

implementation

„ Additional usage of base tags

In contrast to former implementations the CRM Web Client views can be based on a minimal amount of coding

New Component Concept: Inside and Outside View

Inside perspective

„ A component is represented by a component controller – has a context that is partially public to the outside

„ A component consists of custom controllers and one or more windows that host the views

Outside perspective

„ A component can be (re-)used by one or more other components

„ The embedding component defines a component usage in it’s runtime repository to formally declare the dependency

„ Also at runtime the component has access to the component usage to get access to the Interface of the embedded component

„ Each component usage gets it’s own component instance at runtime Each component could be looked at from the inside as well as from

(44)

Component Controller

„ highest level of all controllers

„ is loaded at initial load of component „ can serve as data container

„ manages binding of usages

„ manages data transfer between components

„ Binding of Context Node from custom controller to component controller

(45)

©SAP AG 2007, SAP Skills 2007 Conference / F4 / 45

New Window Concept: Inside and Outside View

Inside: (window aspect)

„ Technically a window is a special type of view

hosts (serves as root viewset ) views and viewsets of the component

has a context that contained views and viewsets can bind to

can trigger navigation inside the window

Outside: (Interface view aspect)

„ has inbound and outbound plugs as entry and exit points from the view of the embedding component

inbound plugs are called when the embedding component navigates to the view

can fire an outbound plugs (e.g. if view request so) to request navigation on the level of the embedding component -> navigation destination is determined by embedding component (runtime repository)

Each Window can as well be seen from the inside as well as from the out-side.

(46)

Component Interface

Needs to be defined if a

component shall be reusable

„ is defined in the runtime repository editor

„ Context nodes of component controller are made visible to outside

(47)

©SAP AG 2007, SAP Skills 2007 Conference / F4 / 47

Component Usage(1)

„ Components with a

component interface can be included in other components (reuse)

„ usages are defined in the runtime repository editor

(48)

Component Usage(2)

„ Component controllers need to be bound against each other

„ this is done in method WD_USAGE_INITIALIZE of the component controller class
