input parameter changes upon function module execution

[rangerlet_mesee]

Hi,

For a Z function module, I am providing an importing parameter UOM..

When I provide a value and execute the FM, it is working fine..

But when I change the UOM input parameter value, upon execution of the FM and coming back to the test screen, I see the old UOM value...

Which means that I am unable to provide a value for UOM parameter as it is taking previous entry or becoming empty..

May I have a clue regarding this issue?

Dear Rangerlet,

   Are you passing by value or by reference. If you are passing value where are you caputuring the returned value. Please check that. can you show as the code.You should also check this in pbo module of your screen.
