We are running World A7.3 and in the process of migrating to 9.3. We have an occasional problem that creates big issues for us. We have a random record show up in the f4105 that has a zero cost. We use 07 std cost and this record looks just like our current std cost, but it is zero. The last program show to have updated or created the record is xt4102z1. Anyone else experienced this problem? Thanks.
