• What is the cause and solution for SAP error message WRF_PRC_BAS027 - Hierarchy level of material hierarchy is not filled ?

  Certainly! Here's a detailed explanation for the SAP error message WRF_PRC_BAS027: Hierarchy level of material hierarchy is not filled:
  
  Error Message
  WRF_PRC_BAS027: Hierarchy level of material hierarchy is not filled
  
  Cause
  This error occurs when the system expects a material hierarchy to be fully defined, but one or more hierarchy levels are missing or not maintained for the material in question. In SAP, material hierarchies are used to classify materials in a structured way, often for reporting, pricing, or classification purposes.
  Specifically, the error indicates that the hierarchy level(s) in the material hierarchy structure have not been filled or maintained properly. This can happen if:
  
  The material hierarchy is incomplete or partially maintained.
  The material master record does not have the required hierarchy levels assigned.
  The hierarchy node or level is missing in the configuration or master data.
  The process or transaction expects a fully maintained hierarchy but encounters missing data.
  
  
  Where It Occurs
  
  During pricing procedures or condition record maintenance where material hierarchies are used.
  When creating or changing material master data if hierarchy levels are mandatory.
  In custom programs or reports that rely on material hierarchy data.
  In sales documents or pricing where material hierarchy is part of the condition technique.
  
  
  Solution
  
  
  Check Material Hierarchy Maintenance:
  
  Go to transaction MMH1 (Create Material Hierarchy) or MMH2 (Change Material Hierarchy).
  Verify that the material hierarchy is fully maintained for all required levels.
  Ensure that the hierarchy nodes exist and are correctly assigned.
  
  
  
  Maintain Material Master Data:
  
  Use transaction MM02 (Change Material) to check the material master.
  Navigate to the relevant views (e.g., Sales: Sales Org. 1 or Classification) and ensure the material hierarchy fields are filled.
  If the material hierarchy is used in pricing, ensure the hierarchy levels are assigned in the material master.
  
  
  
  Check Pricing Condition Records:
  
  Use transaction VK11/VK12 to check condition records that use material hierarchy.
  Ensure that the hierarchy levels used in condition tables are properly maintained.
  
  
  
  Verify Configuration:
  
  Check the configuration of material hierarchy levels in IMG under:
  Logistics - General > Material Master > Settings for Key Fields > Define Material Hierarchy
  Confirm that the hierarchy levels are defined and active.
  
  
  
  Custom Code or User Exits:
  
  If the error occurs in custom programs or user exits, check the logic that reads or processes material hierarchy.
  Ensure that the program handles missing hierarchy levels gracefully or that the data is complete.
  
  
  
  
  Additional Information
  
  Material Hierarchy is a classification tool that allows grouping materials into a hierarchical structure (up to 10 levels).
  It is often used in pricing to apply conditions based on material groups.
  Missing hierarchy levels can cause issues in pricing, reporting, and master data consistency.
  Always ensure that the hierarchy is maintained consistently across all relevant materials.

  Error
  WRF_PRC_BAS027: Hierarchy level of material hierarchy is not filled
  
  
  Cause
  Missing or incomplete material hierarchy levels for the material
  
  
  Solution
  Maintain complete material hierarchy via MMH1/MMH2, update material master (MM02), check pricing condition records, and verify configuration
  
  
  Transactions
  MMH1, MMH2, MM02, VK11, VK12
  
  
  Notes
  Ensure hierarchy levels are consistent and complete to avoid pricing and reporting errors
