ABAP CALL FUNCTION GENERAL Statement syntax and functionality in SAP

CALL FUNCTION func

Short Reference

ABAP Syntax CALL FUNCTION func { parameter_list
|
parameter_tables }.

What does it do? This statement calls the
function module specified in func . The name func must be a character-like data object containing the name of a function module permitted by the package check in uppercase letters when the statement is executed. Each function module in AS ABAP has a unique name, which is why do not need to specify the function group.
The additions parameter_list
or parameter_tables are used to assign (statically or dynamically) actual parameters to the formal parameters of the function module and return codes to the non-class-based exceptions.

Latest notes: If the name of a function module is specified by a constant or as a character literal, the specified function module is checked. If the function module does not exist, the extended program check reports an error. See Dynamic Calls .
