CALL CUSTOMER-FUNCTION

Short Reference

Syntax

CALL CUSTOMER-FUNCTION function_exit parameter_list.

Effect

This statement can be used in programs delivered by SAP. It includes the function module exit specified in function_exit. The function module exit is a customer exit. In an SAP program, it enables you to call a function module provided by SAP and implemented by the customer.

The indicator function_exit must be a three-digit text field literal. A function module exit is specified by SAP using the transaction SMOD and can be activated using the transaction CMOD in customer systems.

• Specifications by SAP
  An empty or partly implemented function module must be assigned to the function module exit using the transaction SMOD. The name of the function module consists of EXIT_, the program name, which contains the statement CALL CUSTOMER-FUNCTION, and the three-digit indicator in function_exit. The interface of the function module is completely defined by SAP.
  
  
• Activation in the customer system
  The transaction CMOD enables the customer to implement the source code of the function module within an enhancement project and to activate the function module exit. If the function module exit is not activated, the statement CALL CUSTOMER-FUNCTION is ignored. If the function module is activated, the corresponding function module is called in the same way as the general function module call.
  

Syntax and meaning of the parameter_list for the assignment of the actual parameters to formal parameters and for the exception handling are the same as in a general function module call. It is not possible to dynamically fill the interface.

Note

As of release 4.6, the function module exits are replaced with class-based Business Add-Ins(BADIs). They do not require their own ABAP statements.
