Sage 200 UKI Ideas Portal

Just starting out using Sage For Education (Sage 200c), and am amazed that there is no automatic checking for duplicate supplier invoices being entered. When entering the invoice information, invoice date, invoice number, you get the tick on the right hand side of the reference box which goes green. We assumed that this meant that the invoice was unique, and continued to enter the details and nominal codes, and posted it. However, the green tick apparently means that it is OK to click on the green tick to manually check that the invoice is unique. This is very misleading to the AP team, who have been entering invoices on, seeing the tick go green, and carrying on. Can I suggest in the next round of improvements that this is looked at, and instead of manually having to check that the invoice is unique, the system tells you automatically, like it does in all the previous accounting software packages I&ve used? This is a significant flaw, and should be a really easy fix to do. Fortunately, the duplicate invoice which was entered was not for a high value, and we picked it up before payment was raised. it could have been a lot different however. Cheers, Ian
