Declaration with LIKE is the correct one...

Please check your Import and Export Parameters , checked on check-box "Pass by value".

Activating RFC .

1: Click on Display Object List icon (Ctrl+shift+F5)

Hi,

I just tried creating a sample RFC FM with tables parameter in the same way as you have done and the FM got successfully activated without the information pop up which you have shown. I used LIKE for the dictionary structure.

I would suggest you click on the 'question mark' icon on your information pop up message to know the reason behind. Thanks.

Hi Kumud,

is yor RFC having any import and export parameter without Checked on "Pass Value" , then you try to active ur RFC then you find above information "Reference parameters are not allowed with RFC"

Hi Smruti,

Thanks

I resolved the message 'Reference parameters are not allowed with RFC' by selecting the option 'Pass by Value' which is also the right way of using Import parameters in FM.

Hi Rier,

Try to activate the whole function group in SE80.

Look at TOP include (LZBAPIFGRPTOP) it MUST begin with "FUNCTION-POOL zbapifgrp". Just add some global data here, but don't remove generated lines. Of course don't remove the "INCLUDE lzbapifgrptop." statement from main program. It is good practice to immediately activate any new function group created before creating the FM.

Raymond

Hi Rier werl,

Default parameters of a FM are passed by reference. This is very efficient because instead of passing the values you are referring to the memory address of variable.

But when you are referring to the Remote Function Modules you have to mark the Pass by Value check box in Import and Export parameters since RFC can be called from anywhere also direct access is not possible so call be reference doesn't work.

So check the pass by value and test it.

Hi Rier,

In RFC Function module we cannot use pass bye reference, it should be pass by value.

So please tick the check box and try again.

Hope this will help you.

Thanks,
