CALL CUSTOMER-FUNCTION
Obsolete 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 three-character name function_exit must be specified directly and included in single quotes ('). A function module exit is specified by SAP using the transaction SMOD and can be activated using the transaction CMOD in customer systems.
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 fill the interface dynamically.
System fields
If the function module exit is not active, sy-subrc retains its previous
value. If the function module exit is active, sy-subrc is set as in CALL FUNCTION.
