I up-sized a 2010 mdb Front-End to 2016 Accde but the Back-end is still mdb format.
it was working fine for four weeks.
Now my customer calls me that they are loosing Detail records from the Invoice table.
i checked and checked for any possibilities that we might be changing that can cause to delete records.
But i don't see anything, i also checked the Advanced Options it's the same as the 2010, Record level-locking etc.
Does anybody have an idea what it could be because it's a big problem?
Thanks in advance
