Line-Level EFF Required Only for Consignment Sales

Hi all,
I’m working in Oracle Fusion Cloud Order Management (Create Orders / Manage Orders) and need to enforce a conditional mandatory rule for a line-level Extensible Flexfield (EFF).

• UI path: Create Order → Lines → Additional Information
• EFF: DOO_FULFILL_LINES_ADD_INFO (Fulfillment Line Additional Information)
• Context: Aprobaciones
• Segment/Field: OrderTransferencia
• Rule: The field must be required only when orderTypeCode = “VENTA CONS”. For all other Order Types it must remain optional.

I implemented an Order Management Groovy validation extension on On Start of Submission Request to validate the field per line. When submitting the order, I get:

DOO-2685874 ... Could not complete extension <OrderTransferencia8> during On Start of Submission Request
