Migrating PO with Charge account in FBDI for destination Type as Inventory

Summary:

We need to migrate PO for Destination type as Inventory. While migrating PO we need to provide PO charge of account in FBDI.

When we pass charge account in FBDI this gets overridden and accounts are generated by TAB.For migration PO we do not want same and would like system to honor the accounts provided in FBDI.

For expense destination type it is working as expected but for Destination type as Inventory it does not honor FBDI passed accounts but derives as per TAB setting.

I checked few documents where they are saying populate in DFF and write TAB to derive values as per DFF.However we do not want to open DFF which would only be used for migration.
