• What is the cause and solution for SAP error message MDC_HDB_MTC030 - Source and target match configurations cannot be the same ?

  The SAP error message MDC_HDB_MTC030, which states "Source and target match configurations cannot be the same," typically occurs in the context of data replication or data transfer processes within SAP HANA, particularly when using the Multi-Target Data Replication (MDC) feature.
  Cause:
  This error arises when the source and target configurations for a data transfer or replication process are identical. In other words, the system is trying to replicate data from a source to a target that is configured in the same way, which is not allowed. This can happen if:
  
  The same database or schema is mistakenly set as both the source and target.
  There is a misconfiguration in the data transfer settings.
  The replication job is incorrectly defined, leading to a conflict in the source and target definitions.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Configuration Settings: Review the source and target configurations in your data replication setup. Ensure that they are not set to the same database or schema.
  
  
  Modify the Target Configuration: If you find that the source and target are indeed the same, change the target configuration to point to a different database or schema that is intended for the data transfer.
  
  
  Review Replication Jobs: If you are using replication jobs, check the job definitions to ensure that they are correctly set up with distinct source and target configurations.
  
  
  Consult Documentation: Refer to the SAP HANA documentation for Multi-Target Data Replication to understand the requirements and limitations regarding source and target configurations.
  
  
  Testing: After making the necessary changes, test the replication process again to ensure that the error is resolved.
