We implemented an iSeries v7r1 over the weekend . In a particular display the user enters records in a subfile in last name order, when he/she pages down to another screen in the subfile the records change to a different order. The display, physical, logicals and programs have not been changed since 2012. This only started to happen after we upgraded to the new machine (power system v7r1. Does anyone know if there are any release notes regarding this problem?
