I want to populate "Gen. Posting Type" field with values: Purchase or Sale on Gen Ledger Entries, the system does not allow me to do so, can anyone help me with this?
Is this what you are talking about:
This field is populated when the user creates a Journal Entry:
The user must populate the filed at that time.......
If they did not, then you will need to reach out to a developer and have the field populated via SQL script.
