why can't i disable closed checkbox on purchase order by workflow

AI generated answer (using internal Slack threads):

The 'Closed' checkbox on a Purchase Order (PO) line might be disabled due to a few reasons: 1. The transaction is locked by a workflow. If a workflow is controlling the transaction, it might prevent changes to the 'Closed' checkbox. 2. There could be a permissions issue. Make sure you are using a role with Full Access or Admin privileges. 3. The custom form being used has the 'Closed' checkbox disabled. Try using the standard PO form instead. If a PO has been accidentally closed and you want to reopen it, you could use a script or workflow. This would iterate through the item lines and mark the 'Closed' checkbox to false. However, please note that this would require some knowledge of SuiteScript.
