How to transfer a PO attribute onto the GL JE lines of the receipt accounting.

Hello everyone, I need to bring onto the accounting records an attribute present on the header of the purchase order. When the PO is received, and the receipts are accounted for, this attribute should be inherited onto the lines of the receipt accounting entry.

To do this, I have created a Supporting Reference with the following source:

• Subledger Application = receipt Accounting
• Event Class = Receiving
• Source = PO Header Flexfield Attribute 6

Subsequently, I accounted for a receipt of a Purchase Order and the attribute value was transferred into XLA in the SR6 field of table XLA_AE_LINES, but not into GL.
