• What is the cause and solution for SAP error message WPS01134 - Root t.l. key &1 / ext. ID &2: Invalid mix of equi and f.loc. task lists ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WPS01134 Root t.l. key &1 / ext. ID &2: Invalid mix of equi and f.loc. task lists
  
  Meaning / Cause:
  This error occurs when there is an attempt to create or use a task list that mixes equipment (equi) and functional location (f.loc.) task lists in a way that is not allowed.
  
  In SAP Plant Maintenance (PM), task lists can be created for either equipment or functional locations.
  A task list is a sequence of operations or maintenance tasks.
  The system expects consistency: a task list assigned to a root task list key must be either all equipment-related or all functional location-related.
  Mixing these two types (equipment and functional location task lists) under the same root task list key or external ID is invalid and causes this error.
  
  
  When does it occur?
  
  When creating or changing task lists.
  When assigning task lists to maintenance plans or orders.
  When copying or referencing task lists.
  When the system detects that the root task list key or external ID is linked to both equipment and functional location task lists.
  
  
  Solution:
  
  
  Check the task list types:
  
  Verify whether the task lists involved are for equipment or functional locations.
  Use transaction codes like IA05 (Change Task List) or IA06 (Display Task List) to check the task list type.
  
  
  
  Ensure consistency:
  
  Make sure that the root task list key or external ID is used only for one type of task list (either equipment or functional location).
  Do not mix equipment and functional location task lists under the same root task list key.
  
  
  
  Correct the task list assignment:
  
  If you find that a root task list key is linked to both types, you need to separate them.
  Create separate root task list keys for equipment and functional location task lists.
  
  
  
  Check maintenance plans or orders:
  
  If the error occurs during maintenance plan processing, check the task list assigned to the plan.
  Ensure the task list type matches the object type (equipment or functional location) of the maintenance plan.
  
  
  
  Data cleanup:
  
  If inconsistent data exists, you may need to clean up or correct the task list assignments in the database.
  Consult with your SAP PM functional consultant or basis team if necessary.
