• What is the cause and solution for SAP error message DMC_RT_MSG621 - System types of the test and production systems are not identical ?

  The SAP error message DMC_RT_MSG621 indicates that there is a mismatch between the system types of the test and production systems in the context of Data Migration Cockpit (DMC) or related data migration processes. This error typically arises when the source and target systems are not configured identically, which can lead to issues during data migration.
  Cause:
  
  Different System Types: The test and production systems may be set up as different types (e.g., one might be a development system while the other is a production system).
  Configuration Mismatches: There may be differences in the configuration settings, such as different versions of SAP, different modules installed, or different data structures.
  Inconsistent Data Models: The data models in the test and production systems may not align, leading to incompatibility during data transfer.
  
  Solution:
  
  Verify System Types: Check the system types of both the test and production environments. Ensure that they are both set up as the same type (e.g., both should be production systems).
  Align Configurations: Review the configurations of both systems and make necessary adjustments to ensure they match. This may involve aligning versions, installed components, or other configuration settings.
  Data Model Consistency: Ensure that the data models in both systems are consistent. This may involve checking for any custom fields, tables, or structures that may differ between the two systems.
  Use the Same Migration Template: Ensure that the same migration template is being used in both systems, as differences in templates can lead to mismatches.
  Consult Documentation: Refer to SAP documentation or support for specific guidelines on aligning system types and configurations.
