the source list could be created automatically?
If yes what does it mean create source list "automatically"?
I usually create source lists manually with trx ME01
source list can be genarated autonmatically while craeting PO, Scheduling agreement, contract, quatation etc by going to the menu and selecting environment and then mainatain source list from there.
you can also generate automatically thru ME05,which will consider all the existing docum,ents
hope it helps
reward if useful
