Update Line Description of the migrated PO's using API

Summary:

We've migrated the PO's via FBDI and post migration we tried to update the line description using rest API and got the below error but we can able to update the line description for the PO's which are directly created in Fusion.

Error - The line description for the specified line item can't deviate from the standard description of the item. (PO-2055274) -

On Further Analysis, I have compared the migrated PO's and direct PO's from backend in PO_lines_ALL table and observed that "ALLOW_DESCRIPTION_UPDATE_FLAG" is set as N for Migrated PO#.

In the FBDI ,we cant see a similar field
