I found this community post [https://community.quickfile.co.uk/t/moving-a-suppliers-invoice-between-suppliers/36332](https://Post 36322)
… that shows how to alter the supplier using a (Modify) link after posting a purchase.
I wonder whether this is a function that has been removed (see screenshot below) or a setting that I haven’t set as I don’t get a link that would save me having to delete and re-enter the transaction (created because two suppliers have similar names that start the same way).
