rel_exp - IS SUPPLIED

Syntax
ABAP_KEY ... para IS [NOT] SUPPLIED ...

Effect
This predicate expression checks whether a formal parameter para of a procedure is filled or requested. The expression is true if at the call an actual parameter was assigned to the formal parameter.
This relational expression can be used only in function modules and methods. For para, you can specify all optional formal parameters.
With addition NOT, the expression is true if at the call no actual parameter was assigned to the formal parameter.
For function modules called with Remote Function Call, the application servers of the calling and called program must have at least release 4.6.

Notes
The predicate expression IS SUPPLIED is not evaluated in function modules that are called using
CALL FUNCTION ... IN UPDATE TASK ...
CALL FUNCTION ... STARTING NEW TASK ...
from an external RFC interface. . In these cases,IS SUPPLIED always returns the value true.
The predicate expression IS SUPPLIED includes the obsolete expression IS REQUESTED.

Example
The logical expression of the first IF statement in method m1 is true if at the call, an actual parameter is assigned to formal parameter p1. A check for the initial value would not be sufficient in this context, because this is the value of the replacement parameter specified with DEFAULT. The logical expression of the second IF statement is true if at the call no actual parameter is assigned to formal parameter p2. CLASS c1 DEFINITION.
