RFC Call not Returning Values

Hello Experts,

I have created RFC enabled function module and calling from another system. RFC connection is working perfectly fine.

This RFC function module don't return anthing when it is being called from system, but when this RFC FM is being called from same system and same parameter it returns correct value.

Is there is any setting that i am missing? Please suggest

Thanks,

Pritam

Code Sample

EXPORTING

port = port

idoc_num = lt_idoc_number

TABLES

idoc_status = idoc_record.
