Validate PO receipt lines against vendor invoice lines

Hi All,

Atthe time of doing a PO receipt I need to validate the lines on the PO receipt against an vendor invoice.

Is there a synchronous event or receiving event that can validate all the receipt lines being saved?

Eg. If the vendor invoice has 5 lines and the PO receipt has just 2 selected then the receipt should not get saved.

The when-validate-record in CUSTOM.pll will only fire for lines that are selected. So if an invoice has 5 lines and the user selects 2, the when-validate-record will just validate the 2 selected and not the other 3 which weren't selected.

Thx!
