• What is the cause and solution for SAP error message CNV_IUUC_DB_CONN129 - SLT Proxy &1 exists with different structure(used by other 1:N consumers) ?

  The SAP error message CNV_IUUC_DB_CONN129 typically occurs in the context of SAP Landscape Transformation (SLT) Replication Server when there is a mismatch in the structure of the database connection proxy. This error indicates that the SLT proxy you are trying to use is already associated with a different structure, which can happen when multiple consumers are trying to use the same proxy with different configurations.
  Cause:
  
  Proxy Structure Mismatch: The SLT proxy is already in use by another 1:N consumer with a different structure. This can happen if the same database connection is being used for different replication configurations that have incompatible structures.
  Configuration Changes: Changes made to the structure of the source or target tables after the initial setup can lead to this error if the SLT proxy is not updated accordingly.
  Multiple Replication Scenarios: If multiple SLT configurations are trying to replicate from the same source table to different target tables with different structures, this can lead to conflicts.
  
  Solution:
  
  Check Existing Proxies: Review the existing SLT proxies and their configurations. Ensure that the proxy you are trying to use is not already associated with a different structure.
  Create a New Proxy: If the existing proxy cannot be modified or is indeed being used by another consumer, consider creating a new SLT proxy specifically for your replication scenario.
  Update Configuration: If the structure of the source or target tables has changed, update the SLT configuration to reflect these changes. This may involve reconfiguring the replication settings.
  Consult Documentation: Refer to the SAP documentation for SLT to understand the specific requirements and limitations regarding proxy usage and structure compatibility.
  Check for Active Replications: Ensure that there are no active replications that might be causing the conflict. You may need to stop or adjust these replications before proceeding.
