Using JCA to call RFM/BAPI's looked very very interesting.
First tried to deploy and run the sample provided. It worked fine and everyone in the team was very excited.
Then we tried to call a RFM to which we needed to pass a Internal Table we tried a lot but couldnt figure out how to do this. JCO's API's were more intutive and easy to learn.
Have anyone tried something similar, If yes please post some sample code.
