• What is the cause and solution for SAP error message ISX_MD_CUST020 - Structure &1 for replication object &2 does not exist ?

  The SAP error message ISX_MD_CUST020 indicates that a specific structure related to a replication object does not exist in the system. This error typically arises in the context of data replication processes, such as those involving SAP Master Data Governance (MDG) or SAP Data Services.
  Cause:
  
  
  Missing Structure: The structure referenced in the error message (denoted as &1) is not defined in the system for the specified replication object (denoted as &2). This could be due to:
  
  The structure not being created or activated.
  The structure being deleted or not transported correctly from a development environment to a production environment.
  A mismatch in the configuration or setup of the replication object.
  
  
  
  Configuration Issues: There may be issues in the configuration settings for the replication object, leading to the system not recognizing the required structure.
  
  
  Transport Issues: If the system is part of a landscape with multiple environments (development, quality, production), the structure may not have been transported correctly.
  
  
  Solution:
  
  
  Check Structure Existence:
  
  Use transaction SE11 (Data Dictionary) to check if the structure exists. Enter the name of the structure (as indicated in the error message) and see if it is defined.
  If it does not exist, you may need to create it or ensure it is properly defined in the system.
  
  
  
  Review Replication Object Configuration:
  
  Go to the relevant configuration settings for the replication object (this could be in transaction MDGIMG or similar, depending on your setup).
  Ensure that the replication object is correctly configured and that all necessary structures are included.
  
  
  
  Transport Check:
  
  If you suspect that the structure is missing due to transport issues, check the transport logs to ensure that all necessary objects were transported correctly.
  If the structure was recently created or modified, ensure that the transport request has been released and imported into the target system.
  
  
  
  Recreate or Adjust the Structure:
  
  If the structure is indeed missing and you have the necessary specifications, you may need to recreate it.
  Ensure that the structure aligns with the requirements of the replication object.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific replication object and structure to ensure compliance with best practices.
  
  
  
  Contact SAP Support:
  
  If the issue persists after checking the above points, consider reaching out to SAP support for further assistance, especially if this is a critical issue affecting business processes.
