Access PO_ReceiptReturnMatRqByPO

How can I access the table object PO_ReceiptReturnMatRqByPO? I need to delete a record from this table which refers to a ghost receipt and locks my PO.

There isn't a file with _bus or _svc, so using NewObject returns "NewObject Error 90".

When I go to the folder C:\Sage\Sage 100 Standard\MAS90\PO, I can't see this table. It only exists inside the companies folder like "MAS_ABX".
Does anyone know?
