Custom setup to populate GL Journal Line DFF with AP Invoice Attribute

Version: 23A

Hello - I wondered if it is possible to do this:

1. Create a DFF on GL Journal Lines e.g. Supplier Name, held in ATTRIBUTE1
2. When Payables Invoice generated via Create Accounting, configure the system to automatically populate the ATTRIBUTE1 DFF on the Journal Line with the Supplier Name from the AP Invoice for which that journal line is for.

I saw on this post that there is a "Manage Subledger Accounting Descriptive Flexfields" Task, but, in a reply, someone from Oracle said:

DFF can only be populated for manual subledger journals.

If you'd like to capture additional information from Accounting Hub data file, then you can implement supporting references instead.
