W_FIP_034 - BAdI: Access Retail Switch

SAP E-Book

This technical Business Add-In (BAdI) is part of a business abstraction layer used internally by SAP. It is not intended for reuse by customers. This technology enables individual functionality or complete applications to be called either by back-end functions or enterprise services. It is used to identify the system as either a standard system or a retail system.

This BAdI uses the following method:

  • READ_RETAIL_SWITCH

BAdI interface IF_EX_W_RETAILSYSTEM_IDENT is implemented or BAdI class CL_EX_W_RETAILSYSTEM_IDENT is in the system.

As with all BAdIs in the ES_FIP_BAL enhancement spot, a developer should never use the GET_BADI call to create an instance of this BAdI. Rather, the developer should first get an instance of the CL_FIP_BAL_FACTORY class and then use its GET_BADI method to instantiate the required BAdI.

Example - Instantiation of tFIhe FIP_BADI_RETAIL_SWITCH_BAL BAdI

DATA:

lo_bal_factory        TYPE REF TO cl_fip_bal_factory,

lo_badi_retail_switch TYPE REF TO fip_badi_retail_switch_bal.

  " Get instance of the BAL factory

  cl_fip_bal_factory=>get_instance(

    IMPORTING eo_factory = lo_bal_factory ).

  " Instantiate the FIP_BADI_RETAIL_SWITCH_BAL BAdI

  lo_badi_retail_switch ?= lo_bal_factory->get_badi(

      cl_fip_const=>gc_badi_def-retail_switch ).

This BAdI was designed to run only one BAdI implementation. It uses a filter named ACCESS_TYPE to determine which implementation is to be executed. Each implementation must have a different filter. In the GET_BADI call to the BAL factory, the value of ACCESS_TYPE is automatically determined and set.

All possible values of ACCESS_TYPE:

  • 0BA
Implementation using BAPIs and/or direct database access
  • 0ES
Implementation using enterprise services, which allows access to different back-ends in case used functionalities are available in different systems.
  • Cnn (where nn is a one-digit or two-digit number)
Customer implementation

The BAL factory class determines the value of the ACCESS_TYPE filter by going through the following process:

  1. Get the value from the FIP_C_BAL_BADI client-specific customizing table.
  2. If a value was not yet obtained, get the value from the FIP_C_BAL_CONF client-specific customizing table.
  3. If a value was not yet obtained, the default value as determined by the BAL factory will be used. In ERP 6.0 EHP4, this value is 0BA.

As of ERP 6.0 EHP4, only 0BA implementations exist for FIP_BADI_RETAIL_SWITCH BAdI that belongs to the ES_FIP_BALenhancement spot.

For information about the implementation of BAdIs in the context of the Enhancement Concept, see SAP Library for SAP NetWeaver under BAdIs - Embedding in the Enhancement Framework.
