Knowing in which table to look for a non-standard activity is a bit of a strange question to ask on this forum. The application administrator of your source system should know if this activity is recorded (because not all systems to record all the activities) and also if this activity is recorded with at least a timestamp

I am working with SAP ECC systems and want to know if there is any standard table used for recording the timestamp of the Payment Proposal Creation activity.

Some of the tables I have in mind are:

·      REGUA: Change of payment proposals (user and time)

·      REGUE: Line items from the settlement in the payment proposal

·      REGUH: Settlement data from payment program

·      REGUP: Processed items from the payment program

·      REGUS: Accounts blocked by payment proposal

But none of these tables has the timestamp.

REGUH should be the source for Payment Proposal Creation, you might need REGUP to link it to the invoices
