How To Fix WRF_APC255 - Material &1 does not belong to hierarchy &2

SAP Error Message - Details

• Message type: E = Error

• Message class: WRF_APC - Messages for Operational Assortment Planning and Control

• Message number: 255

• Message text: Material &1 does not belong to hierarchy &2

What causes this issue?

Material &V1& does not belong to hierarchy ID &V2& and therefore cannot
be used by any purchasing list that uses this hierarchy ID.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Assign your material to the hierarchy ID/Node using transaction
WRF_MATGRP01 or WRF_MATGRP02, or else use another material that belongs
to the current hierarchy ID/Node.

• What is the cause and solution for SAP error message WRF_APC255 - Material &1 does not belong to hierarchy &2 ?

  The SAP error message:
  WRF_APC255 Material &1 does not belong to hierarchy &2
  typically occurs in the context of Product Costing, Profitability Analysis (CO-PA), or Variant Configuration where materials are assigned to specific hierarchies for reporting, costing, or planning purposes.
  
  Cause
  
  The material number (&1) you are trying to process or assign is not assigned to the specified hierarchy (&2).
  This means that the material master data or the related configuration does not include the material in the given hierarchy structure.
  Hierarchies are used in SAP to group materials for reporting, costing roll-ups, or planning. If a material is missing from the hierarchy, SAP cannot correctly process or aggregate data for it.
  This error often arises during:
  
  Costing runs where costing variants or cost component splits rely on hierarchies.
  Profitability Analysis where characteristic values are derived from hierarchies.
  Variant Configuration or classification where hierarchies define valid material groupings.
  
  
  
  
  Solution
  
  
  Check Material Assignment to Hierarchy:
  
  Verify if the material (&1) is assigned to the hierarchy (&2).
  Use transaction codes like:
  
  CKM3 (Material Cost Hierarchy)
  KE4I (Maintain Hierarchies in CO-PA)
  Or check the relevant customizing path depending on the module.
  
  
  
  
  
  Assign Material to Hierarchy:
  
  If the material is missing, assign it to the correct hierarchy.
  This can be done via:
  
  Master data maintenance (e.g., material master classification or hierarchy assignment).
  Customizing settings in SPRO under controlling or costing.
  
  
  
  
  
  Check Hierarchy Definition:
  
  Ensure the hierarchy (&2) is correctly defined and active.
  Sometimes hierarchies are outdated or incomplete.
  
  
  
  Data Consistency Check:
  
  Run consistency checks or reports to identify materials not assigned to hierarchies.
  Correct any inconsistencies found.
  
  
  
  Re-run the Process:
  
  After correcting the assignment, re-execute the costing, planning, or reporting process.
  
  
  
  
  Related Information
  
  Hierarchy in SAP: A hierarchy is a structured grouping of materials or cost objects used for aggregation and reporting.
  Material Master Data: The material must be correctly classified or assigned to the hierarchy in the material master or related configuration.
  Transaction Codes:
  
  CKM3: Display material cost hierarchy.
  KE4I: Maintain hierarchies in CO-PA.
  MM02: Change material master (check classification tab).
  
  
  Customizing Path (example for CO-PA hierarchies):
  
  SPRO ? Controlling ? Profitability Analysis ? Master Data ? Define Characteristics ? Define Hierarchies.
