How to fix negative quantity on hand without location, in Inventory OPM

We are doing the migration to R12.

There are some items with negative on-hand quantities without locators in OPM Inventory.

These issues come from batches had been closed. In those batches, some the ingredients have not been assigned correctly. .

Batches can not be re-open to change the assignement them because the periods were closed and batches has been posted.

How can fix that?

We want to adjust the inventory before to do the migration.

I have been attached a file with example.

Thanks in advance.
