Dynamics NAV "You donot have permissions to modify Item Ledger Entry table"

Hello, one the users for the client i support came up with a crazy request for change. They wanted some data to be added to the external document number from Posted Purchase Invoice for Purchase Receipts.
I had to create a process only report & run it as a batch job to do it.
However on running the report, i received an error above.
The user i was using had super rights in the user permission set.

I looked up the web for some solutions.

The solution is to explicitly add the permission to the object via the object permissions property.
