Hi All,
I realise this is a bit of an open ended question but I've been struggling with this issue for a while now so thought I'd put it to the community for some advice.
We have an ecommerce platform which inserts sales orders into Business Central and populates the External Document Number. I have a copy of what was inserted at the time the sales order was created. It appears that at the invoicing step the external document number changes to a previously used external document number by that customer, I cannot confirm 100% that it's at the invoice step but I fixed a number of them and the next day they had reverted back and the only thing that happened was that they were invoiced. I can compare the external document number that was inserted versus what is on the sales order and accompanying invoice and in many situations they are different, it appears that this has been happening to sales orders/invoices since the early days of our Business Central Instance.
Our Microsoft partner assures me that this field is not referenced in any of our customisations. How would I go about finding the issue? Are there any logs in BC that can be searched to see what is happening to a sales order/invoice as it is acted on? Or is this perhaps a known bug in Business Central (I would find this hard to believe)?
Any advice would be helpful.
Cheers,
Gareth
