Why is the PO FBDI Import validating the BPA item description against the master item description

Summary:

We are importing 1000s of POs from a legacy system every day. We have the item from the legacy system and from this we find the active BPA and line number in SaaS. This information is populated in the FBDI and used to load the PO against the correct BPA and line. However we are seeing errors when the item description on the BPA is out of sync with the item description in Product Hub. If the descriptions are out of synch, we cannot load the line and have to expire the item on the BPA with the old description
