When filling out a purchase requisition a user is able to close/cancel the PrePostiingWithSourceAssistant without filling out the mandatory fields.

`PurchaseRequisition.client`

As this is an after command on a list, a new line is saved anyways.

`PurchaseReqLineNoPartTab.fragment`

`PurchaseReqLinePartTab.fragment`

Is there any way to incorporate some sort of client side Do While loop for a command?

Are there any other suggestions for this issue?

My last option is to prevent the release of the purchase req, but don’t really want to handle communicating to the users what is missing for potentially multiple lines.
