This is the result of discussions on the main forum. It's also my second attempt to post, I lost the first one due to timeout (my fault really). So here's a briefer post.
I'm discussing purchas...
Hi DaveLeonie,
I have done some testing on the invoice number warning and it does appear to be showing as soon as I tab from the Invoice number field for me.
I have tried giving you a call so we can investigate this further but it looks like I have missed you for the day. If you could send me a Private message with your best number and time to call, we would be happy to arrange this for you.
