[13.0] Purchase: Do not add lines from same PO multiple times on the Vendor Bill

[sswapnesh]

Impacted versions: 13.0

Steps to reproduce:

• Select PO on Vendor Bills (It add new Line in Invoice Lines)
• Select Same PO Reference

Current behavior: It adds Same lines multiple times

Expected behavior: Same as v12 where Lines were not duplicated

This would be purchase, not account. I think this is done on purpose for allowing you to repeat data if you want.

@pedrobaeza Title Updated. Not sure and I could not find the Detailed PR message about this one

Maybe some regression as it is pointing to purchase.bill.union not purchase.order

[pedrobaeza]

That's because now it allows to select an old invoice or a pending purchase, but that "pending" thing is relative.

@pedrobaeza I think this is a mistake, it is an error, see the behavior only happen in a very specific situation (video with the PoC).

Why do I think it is a mistake?

1. It does not behave in the same way when quantities are the same as the Po.
2. it is only when no shipping done at least on my example.
3. it is ignored (the second time I used the same PO) as it should do.

I think it is a combination of steps that are doing the bug, related with the messy onchange stuff.

Thanks for your bug report @sswapnesh

OK, then let's put all tags and wait for an answer from the corresponding team.
