• What is the cause and solution for SAP error message T0323 - At least one calendar is required for this working day rule ?

  The SAP error message T0323, "At least one calendar is required for this working day rule," typically occurs in the context of configuring working time rules in SAP, particularly in the Human Capital Management (HCM) module. This error indicates that a working day rule has been defined, but it lacks an associated calendar, which is necessary for the system to determine working days and hours.
  Cause:
  
  Missing Calendar Assignment: The working day rule you are trying to use does not have a calendar assigned to it. Calendars define the working days and hours for employees.
  Incorrect Configuration: The configuration of the working day rule may be incomplete or incorrect, leading to the absence of a calendar.
