I am integrating CRM with ECC. In the integration guide it is written that a RFC USER needs to be created in ECC & CRM for R & R.
I have created RFC user in CRM and now BDOCs for Customer Master download are working fine, i.e. smw01 status is shown as green.
I have one query what is the use of creating RFC user in ECC since I am not assigning it to anything. And what are the repurcussions if I don't create one.
Thanks in advance
