29655 - Details

• The SAP error message 29655, which states "Task list type & is already linked to another object type," typically occurs when you are trying to link a task list (such as a maintenance task list or a production task list) to an object type (like a piece of equipment or a functional location) that is already associated with a different object type. This can happen in various SAP modules, particularly in Plant Maintenance (PM) or Production Planning (PP).
  
  Cause:
  
  Existing Link: The task list you are trying to link is already associated with another object type. For example, if a maintenance task list is already linked to a piece of equipment, you cannot link it to a functional location or another piece of equipment without first removing the existing link.
  Data Integrity Rules: SAP enforces data integrity rules to prevent conflicts and ensure that task lists are not misused or incorrectly assigned.
