  Error Message
  WRF_DISPRO081: Specify a planning calendar
  
  Cause
  This error occurs when a planning calendar is required but has not been specified in the configuration or master data during production planning or scheduling processes. The planning calendar defines the working and non-working days for a work center, production line, or resource, and is essential for accurate scheduling and capacity planning.
  Common scenarios causing this error:
  
  The work center or resource does not have an assigned planning calendar.
  The production order or routing requires a planning calendar but none is maintained.
  The system cannot determine the calendar to use for scheduling due to missing or incomplete data.
  
  
  Solution
  To resolve the error, you need to specify or assign a valid planning calendar in the relevant master data or configuration:
  
  
  Assign a Planning Calendar to the Work Center:
  
  Transaction: CR02 (Change Work Center)
  Navigate to the Scheduling tab.
  In the Capacity section, assign the appropriate Planning Calendar.
  Save the changes.
  
  
  
  Check the Routing or Production Order:
  
  Ensure that the routing or production order references a work center with a valid planning calendar.
  If necessary, update the routing or work center master data.
  
  
  
  Maintain Planning Calendars:
  
  Transaction: SCAL (Maintain Factory Calendars)
  Verify that the planning calendar exists and correctly reflects working/non-working days.
  Create or adjust the calendar if needed.
  
  
  
  Check Configuration:
  
  In some cases, the error may arise due to missing configuration in the production scheduling profile or capacity planning settings.
  Verify that the scheduling profile and related settings are correctly maintained.
  
  
  
  
  Additional Information
  
  The planning calendar is crucial for capacity planning and scheduling to avoid scheduling work on non-working days.
  If multiple calendars exist, ensure the correct one is assigned based on the plant, work center, or resource.
  This error is common in discrete manufacturing and repetitive manufacturing scenarios where scheduling precision is required.
  Always test changes in a development or quality system before applying to production.
