v2023r1--sharing the version because I’m thinking this may be a bug fixed in a later release.
I’ve had a couple of invoices lately brought to my attention where the Bill-To Contact and Address on the sales order (and ultimately the invoice) has a different customer’s details than what is on the customer record. The “Override” checkboxes are not checked.
My best guess is that an order is started for Customer A, and part way in the order taker realizes that they selected the wrong customer and updated it to Customer B. The Ship To Contact details are updated, but the Bill To is not. Unfortunately I haven’t been able to reliably duplicate it (I was able to duplicate it once in our Sandbox, but then following the same steps again it updated the Bill To contacts).
I’m curious if others have run into this or if anyone knows if it may be something addressed in future versions.
