• What is the cause and solution for SAP error message MSR_MM026 - Replacement material cannot be requested when ERS is active ?

  The SAP error message MSR_MM026 indicates that a replacement material cannot be requested when the Evaluated Receipt Settlement (ERS) is active. This error typically arises in the context of materials management and procurement processes within SAP.
  Cause:
  The error occurs because when ERS is enabled for a purchasing document, the system does not allow the use of replacement materials. ERS is a process that allows for automatic invoice creation based on goods receipt data, and it is designed to streamline the procurement process. However, when ERS is active, the system expects that the original material is being processed, and it does not support the replacement of materials in this context.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Disable ERS for the Purchase Order: If the replacement material is necessary, you may need to disable ERS for the specific purchase order. This can be done by changing the settings in the purchase order or by consulting with your SAP administrator to adjust the ERS settings.
  
  
  Use the Original Material: If possible, continue with the original material instead of attempting to replace it. This will allow the process to proceed without triggering the error.
  
  
  Create a New Purchase Order: If the replacement material is essential, consider creating a new purchase order specifically for the replacement material without ERS enabled.
  
  
  Consult Documentation: Review SAP documentation or consult with your SAP support team for specific configurations related to ERS and replacement materials. There may be specific settings or configurations that can be adjusted to accommodate your business needs.
  
  
  Check Material Master Data: Ensure that the material master data for both the original and replacement materials is correctly configured. Sometimes, issues in the material master can lead to errors in procurement processes.
  
  
  Related Information:
  
  ERS Configuration: Understanding how ERS is configured in your SAP system can help in troubleshooting this error. Check the settings in the purchasing view of the material master and the purchasing documents.
  SAP Notes: Look for relevant SAP Notes that may address this specific error or provide additional guidance on handling replacement materials with ERS.
  User Exits or BAdIs: In some cases, custom logic may be implemented through user exits or Business Add-Ins (BAdIs) to handle specific business scenarios involving ERS and replacement materials.
  
  If the issue persists after trying the above solutions, it may be beneficial to engage with your SAP support team or a consultant who specializes in SAP MM (Materials Management) for further assistance.
