PO: Release Creation Tolerance For Expired Blankets; in Days

Dear SCM Gurus,

For the above profile option the local BPA - in the release form works perfectly as expected.

But in the global method:

1) if the GBPA is expired, it is not even available for selection in the catalog function which is available in the PO form!

2) if the GBPA expiry date is 31-dec-2019,selected from the catalog and  when i insert a need by date greater than the expiry date, the line referred by the source document type and document and line details get vanished.

My question is -

1) is the above profile option only for release and not for standard PO referring a GBPA?
