• What is the cause and solution for SAP error message WPS01136 - Root t.l. key &1 / ext. ID &2: Different func. locations within hierarchy ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WPS01136 Root t.l. key &1 / ext. ID &2: Different func. locations within hierarchy
  
  Meaning / Cause:
  This error occurs in the context of Plant Maintenance (PM) or Project System (PS) when working with functional locations (technical locations) in a hierarchy.
  
  The message indicates that the root technical location key (&1) and the external ID (&2) refer to functional locations that are not consistent within the same hierarchy.
  In other words, the system expects all functional locations within a hierarchy to be related or aligned under the same root or parent location.
  If you try to assign or link functional locations that belong to different hierarchies or have different root locations, this error is triggered.
  
  
  Typical Scenarios:
  
  When creating or changing a functional location structure.
  When assigning equipment or objects to functional locations.
  When integrating external data or IDs that do not match the existing hierarchy.
  During data migration or interface processing where external IDs are used.
  
  
  Solution / How to Fix:
  
  
  Check the Functional Location Hierarchy:
  
  Verify that the functional locations involved belong to the same root or parent location.
  Use transaction IL03 (Display Functional Location) to check the hierarchy and root location.
  
  
  
  Correct the Root Location or External ID:
  
  Ensure that the external ID (&2) corresponds to a functional location under the root technical location key (&1).
  If the external ID is incorrect or belongs to a different hierarchy, correct it.
  
  
  
  Adjust the Assignment:
  
  If you are assigning equipment or objects, make sure they are assigned to functional locations within the same hierarchy.
  Avoid mixing functional locations from different hierarchies in the same structure.
  
  
  
  Data Consistency Check:
  
  Run consistency checks or reports to identify functional locations with inconsistent hierarchy assignments.
  Use transaction IL05 (Functional Location List) or custom reports.
  
  
  
  Consult Master Data or Integration Teams:
  
  If the error arises during data import or interface processing, verify the mapping and data consistency.
  Ensure that external systems provide correct and consistent functional location IDs.
  
  
  
  
  Additional Information:
  
  Functional locations in SAP PM are organized in a hierarchical structure to represent the technical system or plant structure.
  The root technical location key is the top-level node in this hierarchy.
  External IDs are often used for integration with other systems or for referencing functional locations uniquely.
  Maintaining consistent hierarchies is crucial for reporting, maintenance planning, and system integrity.

  Error Message
  WPS01136 Root t.l. key &1 / ext. ID &2: Different func. locations within hierarchy
  
  
  Cause
  Functional locations belong to different hierarchies; root key and external ID mismatch
  
  
  Solution
  Verify and correct functional location hierarchy; ensure root and external IDs align
  
  
  Transactions
  IL03 (Display FL), IL05 (List FL), maintenance/change transactions
