• What is the cause and solution for SAP error message WM136 - Material & is a generic material, please enter variant ?

  The SAP error message WM136 ("Material & is a generic material, please enter variant") typically occurs in the Warehouse Management (WM) module when you are trying to process a generic material without specifying a specific variant. Generic materials are used in scenarios where multiple variants of a product exist, and the system requires you to specify which variant you are referring to in order to proceed with the transaction.
  Cause:
  
  Generic Material: The material you are trying to use is defined as a generic material in the system. This means it does not have a specific configuration or variant assigned to it.
  Missing Variant: The transaction you are attempting to perform requires a specific variant of the generic material, but you have not provided one.
  
  Solution:
  To resolve this error, you need to specify the variant of the generic material you are trying to use. Here are the steps you can take:
  
  
  Identify the Variant: Determine which specific variant of the generic material you need to use. This may involve checking the material master data or consulting with your inventory or production team.
  
  
  Enter the Variant: When prompted for the material, enter the specific variant instead of the generic material. This may involve selecting from a list of available variants or entering the variant number directly.
  
  
  Check Material Master: If you are unsure about the variants available for the generic material, you can check the material master record in SAP. Use transaction code MM03 to view the material details and see the variants associated with it.
  
  
  Consult Documentation: If you are still having trouble, refer to your organization's documentation or SAP help resources for guidance on how to handle generic materials and their variants.
  
  
  Related Information:
  
  Material Master Data: Understanding how materials are defined in SAP, including the distinction between generic materials and their variants, is crucial for effective inventory management.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM01 (Create Material), MM02 (Change Material), and MM03 (Display Material) to manage material data.
  Warehouse Management Processes: Knowledge of how warehouse processes work in SAP WM, including picking, putaway, and inventory management, can help you navigate issues related to materials and variants.
  
  If the problem persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in WM for further assistance.
