With reference to Lcs Issue927117:

When a vendor account is set on hold for ‘Purchase order’ and an existing purchase order is modified to add an extra line, no re-validation is performed, and confirmation is made, which is not expected.

As a daily process, purchase orders are amended regardless of the status. New lines will be added by users, who may not be aware that vendor account is on hold for any valid reason.

Introducing a change which will prevent the addition of lines while the vendor is placed on hold for ‘Purchase orders’, would greatly help avoiding any monetary implications which arise as well as any other undesired, directly triggered situation.
