• What is the cause and solution for SAP error message /SAPAPO/CAL220 - To-time of shift &1 exceeds from-time of shift &2 ?

  The SAP error message /SAPAPO/CAL220 indicates that there is a problem with the time settings of a shift in the Advanced Planning and Optimization (APO) module. Specifically, the error states that the "To-time of shift &1 exceeds from-time of shift &2." This typically means that the end time of one shift is set to be earlier than the start time of another shift, which is logically inconsistent.
  Cause:
  
  Incorrect Shift Configuration: The shifts may have been configured incorrectly in the system, leading to overlapping or improperly sequenced times.
  Data Entry Error: There may have been a mistake during data entry, where the end time of a shift was entered incorrectly.
  Time Zone Issues: If the system is set up to handle multiple time zones, there may be discrepancies in how times are interpreted.
  Shift Overlap: There may be an overlap in the defined shifts, causing the system to throw this error.
  
  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 one shift does not overlap or precede the start time of another shift.
  Correct Time Entries: If you find any discrepancies in the time entries, correct them to ensure that the "To-time" of a shift is always later than the "From-time" of the subsequent shift.
  Check for Overlaps: Ensure that there are no overlapping shifts defined in the system. Each shift should have a clear and distinct time range.
  Consult Documentation: If you are unsure about the correct configuration, refer to the SAP documentation or consult with a functional consultant who specializes in SAP APO.
  Testing: After making changes, test the configuration to ensure that the error does not reoccur.
