User Defined Attributes in supplier program not accruing.

Summary:

I defined the UDA (PIM Level) and assigned the value to the item as expected. I then created a Supplier Rebate Program with the same UDA Code as the one assigned to the item (e.g., UDA Code 1006). This UDA Code 1006 is attached to both the item in PIM and the Supplier Program Product Rules.

I loaded the Supplier Invoice CSV file for accrual, and the invoice data was successfully loaded. After that, I ran the "Create Accruals for Channel Batch" ESS job for the specified file and batch number. The job completed successfully.

However, no accrual was generated for the UDA Code Program Line. How can I debug this issue further? I've attached screenshots of the item setup and program line setup for reference.
