Checking optional tables parameter in function

Former Member — Wed, 17 Aug 2005 10:02:34 GMT

Hi!

is there any possibility to check whether an optional tables parameter has actually been passed to a function?

e.g.

function xxx

TABLES tab1 OPTIONAL

how do I know within the function code if the parameter tab1 has been specified when calling the function?

thanks for help.

Welcome to SDN,

yes you can do it, IS SUPPLIED is the key word.

if tab1 <b>IS SUPPLIED</b>.

do something

endif .

docuementation from ABAP key word documenataion.

log_exp - IS SUPPLIED

Syntax

... p IS [NOT] SUPPLIED ...

Effect

The logical expression checks whether a formal parameter p 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 logical expression is possible only in function modules and methods. For p, 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.

Note

The logical expression with IS SUPPLIED cannot be used in function modules that are called with

CALL FUNCTION ... IN UPDATE TASK ...

CALL FUNCTION ... STARTING NEW TASK ...

For function modules called with Remote Function Call, the application servers of calling and called program must have at least release 4.6.

Hope this helps.

Hi,

When you pass an internal table to your FM and if it has some entries in that table then inside FM code you can check for if that parameter is initial. If it is initial then it means nothing is passed to optional table parameter.

i guess the poster has asked whether a particular optional parameter is passed or not

NOT

the parameter holds a value or not

Hi Angelika,

You can also use the code as follows.

IF ITAB[] IS NOT INITIAL.

**DO SOMETHING

ELSE.

**DO SOMETHING

ENDIF.

Cheers,

Sam
