• What is the cause and solution for SAP error message WS213 - Material group & differs from that (&) of material & ?

  SAP Error Message:
  
  WS213: Material group & differs from that (&) of material &
  
  Cause:
  This error occurs when you try to perform a transaction (such as creating or changing a material, or creating a document involving materials) where the material group assigned to a material does not match the material group expected or assigned in the context of the transaction or document.
  For example, if you are creating a purchase order or a goods movement and the material group of the material you enter differs from the material group expected or previously assigned in the document or master data, SAP throws this error to prevent inconsistencies.
  
  Explanation:
  
  Material Group is a classification key used to group materials with similar attributes or usage.
  The system expects consistency in material groups when materials are referenced or combined in certain transactions.
  If the material group of the material you enter differs from the material group already assigned or expected, the system raises this error to avoid data inconsistencies.
  
  
  Common Scenarios:
  
  Creating or changing a material where the material group entered differs from the existing material group.
  Entering a material in a document (e.g., purchase order, production order) where the material group conflicts with the group assigned to other materials or the document header.
  Copying or referencing materials where the material group is inconsistent.
  
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to transaction MM03 (Display Material).
  Verify the material group assigned to the material.
  If the material group is incorrect, and you have authorization, change it in MM02 (Change Material).
  
  
  
  Check Document or Transaction Data:
  
  If the error occurs during document creation (e.g., purchase order, production order), check the material groups of all materials involved.
  Ensure that the material groups are consistent or as expected by the business process.
  
  
  
  Adjust Material Group:
  
  If the material group is incorrect or inconsistent, correct it either in the material master or in the document, depending on the business requirement.
  
  
  
  Consult Business Process:
  
  Sometimes, the error indicates a business rule violation. Confirm with the business team whether the material group should be changed or if a different material should be used.
  
  
  
  Check Customizing:
  
  In some cases, the system may have validations or user-exits that enforce material group consistency.
  Review any custom code or configuration that might cause this check.
