When I try to load time in CATS or directly in IT2002 using PA30, I am getting warnings - "Attendance/absence 01/18/2012 - 01/18/2012 during non-working period (att./abs.type 0800)" and "First day 01/18/2012 of attendance/absence is a day off (att./absence type 0800)". The system is up and running since long. At the start of this year also, we generated the Work schedules for the year 2012. Even I have checked that the work schedule for the PERNR is correct. The day we are trying to enter time is not a Day off. In fact, we are getting this error for every day we try to enter the attendance for. Please advise what could be cause of this issue, and how to resolve it?
