function module exit
Customer exit for
ABAP programs in the form of empty or partially implemented
function modules delivered
with the standard SAP system. Incorporated in ABAP programs using the statement CALL CUSTOMER-FUNCTION. The function module
interfaces are predefined by SAP. The implementation can be empty or partially predefined. The customer must fully implement and activate them using
transaction CMOD. We recommend replacing function module exits by
BAdIs.
