• What is the cause and solution for SAP error message PLMDISCALC054 - Low-level code of &1 materials/classes was not determined (recursion) ?

  The SAP error message PLMDISCALC054 indicates that the system was unable to determine the low-level code for certain materials or classes due to a recursion issue. This typically occurs in the context of Product Lifecycle Management (PLM) or when dealing with material master data and their hierarchical structures.
  Cause:
  
  Recursion in BOM or Hierarchy: The error often arises when there is a circular reference in the Bill of Materials (BOM) or in the material hierarchy. This means that the system is trying to resolve a low-level code but encounters a loop in the relationships between materials or classes.
  Missing Data: There may be missing or incomplete data in the material master records or BOMs that prevents the system from determining the low-level code.
  Configuration Issues: Incorrect configuration settings in the material management or PLM modules can lead to this error.
  
  Solution:
  
  Check BOM and Material Hierarchies: Review the BOMs and material hierarchies for circular references. Ensure that there are no loops in the relationships between materials.
  Data Consistency: Verify that all relevant material master data is complete and consistent. Check for any missing components or incorrect settings in the material records.
  Use Transaction Codes: Utilize transaction codes like CS03 (Display BOM) or MM03 (Display Material) to inspect the BOM and material details for any inconsistencies.
  Debugging: If you have access to technical resources, consider debugging the process to identify where the recursion is occurring. This may involve looking at the function modules or methods that are being called during the low-level code determination.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error. There may be patches or updates that resolve known issues related to low-level code determination.
  Consult Documentation: Review SAP documentation related to PLM and material management for best practices on structuring BOMs and material hierarchies.
  
  Related Information:
  
  Low-Level Code: The low-level code is a number that indicates the level of a material in a BOM hierarchy. It is used for planning and production purposes.
  Material Master Data: This is a central repository of information about materials that an organization uses. It includes data such as descriptions, units of measure, and BOMs.
  BOM (Bill of Materials): A BOM is a comprehensive list of materials, components, and assemblies required to manufacture a product.
  
  If the issue persists after checking the above points, it may be beneficial to engage with SAP support or a consultant who specializes in SAP PLM for further assistance.
