• What is the cause and solution for SAP error message /SAPAPO/CAL222 - From-time of shift #1 precedes to-time of previous day ?

  The SAP error message /SAPAPO/CAL222 indicates that there is a problem with the time intervals defined for a shift in the Advanced Planning and Optimization (APO) module. Specifically, the error states that the "From-time of shift #1 precedes to-time of previous day," which means that the starting time of the current shift overlaps or is incorrectly defined in relation to the ending time of the previous day's shift.
  Cause:
  
  Shift Configuration: The shift times may be incorrectly configured in the system. For example, if the first shift of a day starts before the last shift of the previous day ends, this will trigger the error.
  Time Overlap: There may be an overlap in the defined time intervals for shifts, leading to conflicts in scheduling.
  Incorrect Date Settings: The date settings for the shifts may not be aligned correctly, causing the system to interpret the times incorrectly.
  
  Solution:
  
  Review Shift Definitions: Go to the shift definitions in the APO system and check the start and end times for each shift. Ensure that the end time of the last shift of the previous day does not exceed the start time of the first shift of the current day.
  Adjust Time Intervals: If there is an overlap, adjust the time intervals so that they are sequential and do not conflict. For example, if Shift #1 starts at 08:00 and Shift #2 ends at 07:00, you need to adjust the times accordingly.
  Check Calendar Settings: Ensure that the calendar settings for the shifts are correctly defined. This includes checking for any holidays or non-working days that may affect the shift timings.
  Test Changes: After making adjustments, test the changes by trying to create or modify a planning scenario that uses the shifts to ensure that the error no longer occurs.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like /SAPAPO/SHIFT to access and modify shift definitions.
  Documentation: Refer to SAP documentation or help files for detailed instructions on configuring shifts in APO.
  Support: If the issue persists after making adjustments, consider reaching out to SAP support or consulting with an SAP APO expert for further assistance.
  
  By following these steps, you should be able to resolve the error message /SAPAPO/CAL222 and ensure that your shift configurations are correctly set up in the system.
