How is the posting key determined?

Hi,

I have a general question about posting keys.

What is the logic behind the posting keys (customizing OB41)?

I think we have 2 possibilities:

With automatic postings, the posting keys are picked up from the "Account assignment" in Customizing (OMWB).

With manual postings, the posting key is selected manually when making the posting.

Do you have any more information about it?

Thank you for your feedback.

Kind regards,

Linda
