Read optional table explicitly from an RFC-Call

[Former Member]

Hello Guru,

I'm having a Problem with RFC-Function-Module.

In my function module I read an optional table called myops_table like this way

Read table myops_table

IF myops_table IS NOT INITIAL

• DO something

ENDIF.

The problem that I removed the instruction "Read table myops_table" and after calling the function module with an external program using RFC, the table is INITIAL and the program is not working correctly.

But, if I do this in SAP, the program works fine without having the read-instruction.

Has this to do that the optional table is not buffered and that man need to read it first.

Best Regards,

Hello,

You might have to try like this

IF myops_table[] IS NOT INITIAL.
* DO something
ENDIF.

IF myops_table  IS NOT INITIAL. "it refers only the header and not the actual data.

Thanks Vikranth.

Now, I'm aware about it.

But could you explain me why it works fine in SAP and not well by an RFC-Call.

Is this has to do of the fact that the table optional. So, the header is not set by an RFC-Call when this table is optional. By it's set on a direct call.

Should I do this by all the tables whether they are optional or not.

Hello Kias,

Not really sure why its not working in a RFC call. Could be that the headers are getting intitialized automatically during a RFC and not when running within SAP. But i dont think this has anything to do with tables parameter being a optional or mandatory.

The correct method to check if a table is initial or not is only by specifying []. You will have to do this to all tables to avoid any inconsistencies.
