Working with SRM 5.0 or 5.5 the use of XI for integration with ECC is not mandatory because when we send any document from ECC to SRM like requisitions (to convert them in shopping cards) or when we send any document from SRM to ECC like shopping cards, PO´s, contracts, we only use the RFC´s and the abap programs.
Is the same behavior with SRM 7.0?????
Could the integration from SRM 7 with ECC 6 work with RFC´S without XI or for this vertions is XI mandatory?????
