  Meaning / Cause:
  This error occurs during the conversion or migration of task lists (e.g., from an older system or during a system upgrade) when the system tries to convert or map a work center but cannot find a corresponding conversion rule for the specified work center.
  
  Task list &1: The task list number or identifier being processed.
  Work center &2: The work center for which no conversion rule exists.
  
  In other words, the system is trying to convert or interpret the work center data in the task list, but there is no defined rule or mapping that tells the system how to handle this particular work center during the conversion process.
