Block Purchase Order Creation on Jobs
When a job is blocked for purchasing, it is no longer possible to create purchase orders.
If you have existing purchase orders on the job, you can still invoice them, but you cannot modify them.
When you create or update a purchase order from the Purchase Orders single dialog workspace, jobs that are blocked for purchasing do not appear in searches for creating or updating purchase orders in the system. An error message displays if you attempt to change the job number on the purchase order to that of a blocked job, or when you add or update a purchase order line related to the blocked job.
Additionally, when you create a job using a template that has enabled this feature, it is also automatically blocked for purchasing. This also happens when you copy a job that is blocked for purchasing.
To block purchase order creation, select the Purchasing option on the Blocked field in .
