I'm new to SAP and CRM. I'm from Java/J2EE background with knowledge about CRM but i want to move into SAP CRM technical side. I want to learn ABAP first. If anyone has any ABAP development guides please send it to me. I'm basically looking at creating some simple tables, and RFCs to set and get data from these tables in SAP CRM.
Also, any documents on how to code custom BAPIs/IDOCs and user exits/BADIs.
Thanks,
