Hi,

Yes you can you can simple copy it as an RFC enabled FM by coping it in your z FM ans assign it to the same FG.

Hi Vinay,

Yes, this will work. Select RFC radio button in the Processing type in the attributes in FM screen.

Hope this helps you. Reply for queries, shall post the updates.

Please don't copy the READ_TEXT function module - just write a "Z" function module that is a wrapper around the standard functionality, and then RFC-enable your "Z" function.

This way, if SAP delivers corrections and enhancements to the READ_TEXT functionality your code will still be up-to-date... if you take a copy, then your code will fall behind SAP's version.

Create a new function module in SE37, e.g. Z_RFC_READ_TEXT and tick that it is RFC enabled. The Import, Export, and Tables parameters should mirror those in READ_TEXT, but you might like to add another table so you can return any exception messages to the caller (e.g. "OT_RETURN" with a structure like BAPIRET2)... you might also have local standard for naming parameters in custom code which you may need to follow. Inside your "Z" function module you just call 'READ_TEXT' using the parameters of the "Z" function. Any exceptions from 'READ_TEXT' should be added into OT_RETURN so that the external caller can be advised of the problem.
