• What is the cause and solution for SAP error message WM398 - No variants found for generic material number & ?

  The SAP error message WM398 ("No variants found for generic material number &") typically occurs in the Warehouse Management (WM) module when the system is unable to find a specific variant for a generic material number during a transaction. This can happen in various scenarios, such as during picking, putaway, or inventory management processes.
  Cause:
  
  Generic Material Number: The material number being used is a generic material number, which means it does not refer to a specific variant of the material.
  Missing Variants: There are no variants defined for the generic material number in the system. Variants are often used for materials that have different characteristics (like size, color, etc.).
  Configuration Issues: There may be configuration issues in the material master or warehouse management settings that prevent the system from recognizing the variants.
  Data Inconsistency: There could be inconsistencies in the data related to the material master or the warehouse management setup.
  
  Solution:
  
  
  Check Material Master: Verify the material master data for the generic material number. Ensure that the variants are correctly defined and that they exist in the system.
  
  Use transaction code MM03 to display the material master and check the "Basic Data" and "Sales" views for variant information.
  
  
  
  Define Variants: If no variants are defined, you may need to create them. This can be done by using transaction code MM01 to create new material variants under the generic material number.
  
  
  Check WM Configuration: Review the Warehouse Management configuration to ensure that it is set up correctly to handle generic materials and their variants.
  
  Use transaction code SPRO to access the configuration settings and navigate to the relevant sections for WM and material management.
  
  
  
  Check for Data Consistency: Run consistency checks to ensure that there are no data inconsistencies in the material master or WM settings. This can sometimes be done using transaction codes like MM02 for changes or MM17 for mass changes.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling generic materials and variants in your version of SAP.
  
  
  Contact Support: If the issue persists after checking the above points, consider reaching out to your SAP support team or consulting with SAP support for further assistance.
  
  
  Related Information:
