• What is the cause and solution for SAP error message DG660 - Material &1 was exchanged for material &2 ?

  The SAP error message DG660 indicates that a material (identified as &1) has been exchanged for another material (identified as &2). This typically occurs in the context of material management and inventory processes, particularly when dealing with material substitutions or changes in material specifications.
  Cause:
  
  
  Material Substitution: The error often arises when a material that is being processed (e.g., in a sales order, purchase order, or production order) has been replaced or substituted with another material. This can happen due to various reasons such as:
  
  The original material is no longer available.
  The original material has been replaced by a new version or a different product.
  Changes in inventory management or procurement processes.
  
  
  
  Configuration Issues: There may be configuration settings in the material master or in the substitution settings that are causing the system to automatically substitute one material for another.
  
  
  Data Entry Errors: Incorrect data entry during the creation of orders or material master records can lead to this error.
  
  
  Solution:
  
  
  Review Material Master Records: Check the material master records for both materials involved. Ensure that the substitution settings are correctly configured and that the materials are set up properly.
  
  
  Check Substitution Settings: If material substitution is intended, verify the substitution settings in the system. This can be done in the material master under the "Basic Data" or "Sales" views, depending on the context.
  
  
  Update Orders: If the substitution is not intended, you may need to update the relevant orders or documents to reflect the correct material. This may involve changing the order line items or re-creating the order with the correct material.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling material substitutions and related error messages.
  
  
  Contact Support: If the issue persists and cannot be resolved through the above steps, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM03 (Display Material), ME21N (Create Purchase Order), or VA01 (Create Sales Order) to investigate the materials involved.
  Material Types: Understand the different material types in SAP (e.g., finished goods, raw materials, trading goods) and how they may affect substitution processes.
  User Exits and BAdIs: In some cases, custom logic may be implemented through user exits or Business Add-Ins (BAdIs) that could affect material substitution behavior.
  
  By following these steps, you should be able to identify the cause of the DG660 error and implement a suitable solution.
