Mosaic’s working as intended, but you’ll need to read on and do a couple of checks to confirm that.
Customers often see one of the two scenarios above because they entered the invoices manually into the system.
If you didn’t record a purchase order against the Invoice ID at the time of entry, you can’t search for it using the purchase order number in the ‘Find Invoice/Credit Note’ screen, and the purchase order number won’t show on the ‘Invoice details’ screen.
Invoices can have a null purchase order because they can hold multiple purchase orders on one invoice. You’ll set this in the Invoice screens at the top left when you click the Amend button on the ‘Invoice details’ screen to go inside the invoice.
Check out the screenshot below and note that all the names are dummy persons from our test instance:
When you're searching for an invoice, the purchase order number field on advanced find only looks at the header. If you've set it for multiple purchase orders on the invoice, there won't be a match since advanced find looks for a specific purchase order on a specific invoice.
So, if you can check the invoice where you expect to see a purchase order ID, or if you search via a different means in Advanced Find and see it was added as 'Multiple', then Mosaic's working as designed in this context.
If you attached your invoice to a specific purchase order ID and see an empty widget on the Invoice details screen, or you can't find it when searching via the 'Find Invoice/Credit Note' screen, please raise a new case online and reference the title of this article with the following:
Provide a fully redacted screenshot of the Invoice (like the example above).
Explain how and where the system's not behaving as you'd expect.
