  The SAP error message DRF_COMMON021 indicates that there is an inconsistency in the Application Link Enabling (ALE) configuration for the target system and the specified message type. This error typically arises in the context of SAP's Data Replication Framework (DRF) when trying to replicate data between systems.
  Cause:
  The error can be caused by several factors, including:
  
  
  Missing or Incorrect ALE Configuration: The target system may not have the necessary ALE configuration set up for the specified message type. This includes settings related to logical systems, distribution model, and message types.
  
  
  Inconsistent Message Type Settings: The message type specified may not be correctly defined in the target system or may not be included in the distribution model.
  
  
  Logical System Issues: The logical system for the target system may not be correctly defined or may not match the expected configuration.
  
  
  Transport Issues: If the configuration was recently transported from one system to another, there may be inconsistencies due to missing or incomplete transport requests.
  
  
  Solution:
  To resolve the DRF_COMMON021 error, follow these steps:
  
  
  Check ALE Configuration:
  
  Go to transaction BD64 (Distribution Model) and verify that the message type is included in the distribution model for the target system.
  Ensure that the logical system for the target system is correctly defined in transaction BD54 (Logical Systems).
  
  
  
  Verify Message Type Settings:
  
  Check the message type configuration in transaction WE81 (Message Types) to ensure that the message type is correctly defined.
  Ensure that the message type is active and properly configured for the target system.
  
  
  
  Review Partner Profiles:
  
  Use transaction WE20 (Partner Profiles) to check the partner profiles for the target system. Ensure that the necessary settings for the message type are correctly configured.
  
  
  
  Check for Transport Issues:
  
  If the configuration was recently transported, ensure that all necessary transport requests were successfully imported and that there are no missing objects.
  
  
  
  Test the Configuration:
  
  After making the necessary adjustments, test the configuration by attempting to replicate data again to see if the error persists.
