I am trying to investigate how a particular material document is being created. I went into se16n and got a list of material documents in table MKPF. I can see that the transaction code used to create these material documents is MFBF or MB26 but, I am not sure how these documents were created. Whether they were created manually by going to that particular t-code or whether they were created by some back job. Is there is a way to find out the process through which these documents were created.
