AWE Purchase Order Approval "Hold" option

Hello!

I am looking for information about the Hold option on a purchase order approval page. What functionality it is supposed to provide and how it is intented to work.

We are currently encountering an issue where an approver of a purchase order selects the hold option which appears to insert an information request back to the previous or initial approver. When this happens, the next time PODISP runs, the PO is dispatched to the Supplier via Email.

I would have thought that by selecting hold on the approval page, this would stop further processing. The PO wasn't actually approved.
