  SAP Error Message:
  WPS01135 Root task list key &1 / ext. ID &2: Different equipments within hierarchy
  
  Meaning / Cause:
  This error occurs when you try to create or use a task list (usually a maintenance task list) that is assigned to a root task list key or external ID, but the equipment hierarchy involved contains different equipment numbers that are inconsistent or conflicting within the task list structure.
  In other words, the system expects the task list to be associated with a single equipment or a consistent equipment hierarchy, but it detects multiple different equipment numbers within the hierarchy, which is not allowed.
  This typically happens when:
  
  You try to assign a task list to a root task list key that is linked to multiple different equipment numbers.
  The equipment hierarchy in the task list is inconsistent or incorrectly maintained.
  There is a mismatch between the equipment assigned to the task list and the equipment in the hierarchy.
  
  
  When does it occur?
  
  During creation or change of a task list (especially maintenance task lists).
  When assigning or referencing a root task list key or external ID.
  When the system validates the equipment hierarchy linked to the task list.
  
  
  Solution / How to fix:
  
  
  Check Equipment Hierarchy:
  
  Verify the equipment numbers assigned within the task list hierarchy.
  Ensure that the equipment hierarchy is consistent and does not contain conflicting equipment numbers.
  
  
  
  Review Root Task List Key:
  
  Check the root task list key or external ID &2 mentioned in the error.
  Confirm that it is assigned to a single equipment or a consistent equipment hierarchy.
  
  
  
  Correct Equipment Assignments:
  
  If multiple different equipment numbers are assigned incorrectly, correct the assignments.
  Use transaction codes like IL02 (Change Equipment) or IA02 (Change Functional Location) to verify and correct equipment data.
  
  
  
  Task List Maintenance:
  
  Use transaction IA05 or IA06 to check and maintain task lists.
  Ensure that the task list is created for the correct equipment or functional location.
