• What is the cause and solution for SAP error message WS105 - Calendar & insufficiently maintained (please maintain) ?

  SAP Error Message:
  
  WS105 Calendar & insufficiently maintained (please maintain)
  
  Cause:
  This error occurs when the system tries to process a transaction or operation that requires a work calendar, but the relevant calendar is either not maintained or incomplete in the system. The calendar might be missing key data such as public holidays, factory holidays, or working/non-working days, which are essential for scheduling, time evaluation, production planning, or other time-dependent processes.
  
  Where it typically occurs:
  
  Time management (e.g., personnel time evaluation)
  Production planning and scheduling
  Work scheduling in Plant Maintenance or Project System
  Any process that depends on factory or public holiday calendars
  
  
  Solution:
  
  
  Identify the Calendar:
  
  Determine which calendar is causing the issue. This is usually the factory calendar or public holiday calendar assigned to the relevant plant, personnel area, or work center.
  
  
  Maintain the Calendar:
  
  Go to transaction SCAL (Factory Calendar Maintenance).
  Select the relevant calendar.
  Check if the calendar is created and active.
  Maintain the public holidays, factory holidays, and weekly work schedules.
  Ensure that the calendar covers the relevant time period (e.g., the fiscal year or the period for which the process is running).
  
  
  
  Assign the Calendar Correctly:
  
  Verify that the calendar is correctly assigned to the organizational units (plants, personnel areas, work centers).
  For personnel time management, check the assignment in Infotype 0007 (Planned Working Time).
  For production/work scheduling, check the work center or plant master data.
  
  
  
  Re-run the Process:
  After maintaining the calendar, re-execute the process that triggered the error.
  
  
  
  Additional Information:
  
  Transaction SCAL: Central transaction for maintaining factory calendars and public holidays.
  Factory Calendar: Defines working and non-working days for a plant or organizational unit.
  Public Holidays: Must be maintained for each country and region as applicable.
  Integration: Many SAP modules rely on accurate calendar data for correct time calculations.
  Common Mistake: Sometimes calendars are created but not assigned or not maintained for the relevant period.
