Duplicate supplier reference

Hi is there any way of finding a duplicated supplier reference id for a receipt entered. The system warned of a duplicated supplier reference id but does not show which one it is related too.
Is there a section to show duplicated supplier reference id

you could search the supplier ref number. Go to your Supplier page and click Search at the top.

Hope this helps.

It came up when I was saving a load of invoices in bulk purchase entry about 100 from one supplier. But did not say which invoices have the same supplier reference number or even highlighted them. I have looked through the invoices and no amounts are the same.
It would be good if they could make it so it shows the duplicated ones just so you can check what is right from wrong.

Thanks for your help
