We have a requirement to configure IDOC's for Cost Center (COSMAS) and Projects (PROJECT). We need to be able to generate IDOC files (CSV format) and drop them under a specific folder under AL11. My Basis team says that since we are only dealing with one system and not sending out IDOC files to an external system, we don't need to use the Transactional RFC port under WE21 T-Code. Attached are the instructions we followed to configure the IDOC's but I feel like something isn't correct. Can anyone please let me know how I can configure these two IDOC files?
