Crystal Reporting against SAP function modules
I am relatively new to the SAP environment and I have created reports against SAP infosets before except for function modules.
I am trying to gauge the performance on reporting between infosets and function modules. I am able to view all the function modules in crystal reports and tried mapping the fields beginning with I_ IS( if i am right) to the design window and i don't see any records in the preview tab. The function module in question is also RFC enabled.
The function module is /RPM/ITEM_GETLIST ( SAP xRPM) which gives me the list of all portfolio items.
Is there any documentation I can refer to on how i can carry out reporting against function modules and web services? I would also like to know your opinions on the performances regarding these approaches. I would appreciate your help and expertise in this topic. Thanks a lot.
PS:- Do let me know if i need to post this question in other forums.
