iProcurement 11.5.8 - How to revise BPA buyer name and expiry date

Hi all,

On iProcurement 11.5.8, how could we revise (1) BPA buyer name and (2) expiry date for approved BPA?

(1) BPA buyer name

The original buyer has left the organization, so we want to update the buyer name.

Have checked solution such as Mass Update of Purchasing Documents, but it seems not available on 11.5.0.

(2) Expiry date

And for expiry date, since the BPA has expired, so it could not be called out as PO to change its expiry date.

Thanks a lot.
