I was creating the schedule records in SAP for year 2017. After successful creation of schedule records, I tried creating a MRO and entering reads through EL28 but I was getting message " ISU_DB_EGER_SELECT_CUTOFF called" while entering reads. Is it due to some error while creating schedule records? I checked in other SAP system, I am not getting this message while entering reads. Once the schedule records of 2017 got overlapped with 2016 calender year but I deleted them and recreated those entries.Please suggest.
