• What is the cause and solution for SAP error message WS104 - Active version of calendar & does not currently exist in system ?

  SAP Error Message:
  
  WS104 - Active version of calendar & does not currently exist in system
  
  Cause:
  This error occurs when the system tries to access or use a public holiday calendar or factory calendar version that is marked as active but does not actually exist in the system. In other words, the system expects an active version of a calendar (e.g., factory calendar or holiday calendar) to be present, but it cannot find it in the database.
  Common scenarios include:
  
  The calendar version was deleted or never created.
  The calendar version is inactive or not maintained properly.
  The system is referencing a calendar version that is not valid for the current date or context.
  
  
  Explanation:
  In SAP, calendars (factory calendars, public holiday calendars) are maintained with versions. Each version is valid for a certain period and can be active or inactive. When scheduling or time evaluation processes run, they look for the active calendar version valid for the date in question.
  If the system cannot find an active version, it throws the WS104 error.
  
  Solution:
  
  
  Check Calendar Versions:
  
  Go to transaction SCAL (Factory Calendar Maintenance).
  Select the relevant calendar.
  Check the versions tab to see if there is an active version valid for the date in question.
  If no active version exists, create a new version or activate an existing one.
  
  
  
  Create or Activate Calendar Version:
  
  If no version exists, create a new version by copying an existing one or creating from scratch.
  Set the validity period correctly.
  Mark the version as active.
  
  
  
  Check Integration Points:
  
  Verify if the calendar is correctly assigned in the relevant configuration (e.g., in work center, personnel planning, or time evaluation).
  Ensure that the calendar referenced in the configuration matches the calendar with an active version.
  
  
  
  Transport Issues:
  
  Sometimes, calendar versions are not transported properly between systems (e.g., from development to production).
  Check if the calendar version exists in the target system.
  Transport the calendar version if missing.
  
  
  
  Check Date Context:
  
  Ensure that the date for which the calendar is being accessed falls within the validity period of the active calendar version.
