Naming the Function Module and the Function Module Group (SAP Library - BAPI Programming Guide Reference (CA-BFA))

Naming the Function Module and the Function Module Group

Purpose

Here you specify the name of the function module the BAPI is based on.

You must also specify the function group that you want to assign this function module to. If there is not an appropriate function group, you have to specify a name for a new function group.

Process Flow

Assigning a Name to the Function Module

Choose a name for the function module which gives an indication of what the BAPI is used for.

The naming convention for BAPIs is BAPI_<Name of object type>_<method name>. You cannot exceed the maximum length of 30 characters. If need be, abbreviate the name of the method so that the assignment to the business object and to the BAPI is retained.

Example

In the case of a GetDetail() BAPI, which reads details for the object type Flight, the name of the associated function module is BAPI_FLIGHT_GETDETAIL.

Specifying the Function Group

All BAPIs belonging to one SAP business object type should be created in one function group, if possible. BAPIs belonging to different SAP business object types must not be created in the same function group.

Ascertain whether a function group has already been created for the BAPIs of the SAP business object type in question. If a function group does not already exist, specify a name for one to be created.

As the basis for naming the function group, you can use either the default technical name (object type) of the SAP business object type or its object name.

The technical name (object type) of an SAP business object type usually takes the form of BUSnnnn, where n is a number. Use the suffix "nnnn" as the technical name of the function group. For example, if the technical name of the object type is BUS1008, then the associated BAPI function group is called 1008.

To find out the technical name of the business object type, open the object type in the Business Object Repository (BOR), as described in the section Determining the Object Type and Its Key Fields. To display further details (the technical name, for example), double-click the name of the business object type.

The object name of an SAP business object type can be used for the name of the function group. For example, all BAPIs associated with the business object type, CompanyCode, could be stored in a function group called Companycode.
