Hello Gurus!
We are facing an issue which is inconsistent and were hoping that one of you may have faced it in the past (we sure haven't and it is quite confusing).
Basically, the Order Management team creates an order. They can select the customer, the bill-to and the ship-to. Once processed and shipped, the AR team runs AutoInvoice to create a bill as always.
For some reason, the customer information is not being populated into the interface tables and we obtain the following error but only for some specific customers (the majority of them go through just fine).
