• What is the cause and solution for SAP error message RD185 - DataSource &1 is defined for a different type of delta processing ?

  The SAP error message RD185 indicates that there is a mismatch in the delta processing type for a DataSource. This typically occurs when you attempt to use a DataSource that is configured for a specific type of delta processing (e.g., "full" or "delta") in a way that is not compatible with its configuration.
  Cause:
  The error can arise from several scenarios:
  
  Incorrect Delta Type Configuration: The DataSource is set up for a different type of delta processing than what is being attempted. For example, if the DataSource is configured for "initial load" but you are trying to perform a delta load.
  Inconsistent Delta Handling: If the DataSource was changed or reconfigured after it was initially set up, it may lead to inconsistencies in how delta processing is handled.
  DataSource Activation Issues: If the DataSource has not been activated properly after changes, it may lead to this error.
  Source System Changes: Changes in the source system that affect the DataSource configuration can also lead to this error.
  
  Solution:
  To resolve the RD185 error, you can take the following steps:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP system (transaction code RSA1).
  Verify the delta type configuration of the DataSource. Ensure that it matches the type of delta processing you are trying to perform.
  
  
  
  Re-activate the DataSource:
  
  If there have been changes to the DataSource, try reactivating it. This can be done in the DataSource maintenance screen.
  After reactivation, check if the error persists.
  
  
  
  Review Delta Process:
  
  Ensure that you are using the correct delta process for the DataSource. If it is set for "full" load, you should not attempt to run a delta load.
  
  
  
  Check for Source System Changes:
  
  If there have been changes in the source system (like changes in the underlying tables or structures), ensure that the DataSource is still valid and correctly configured.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation for the specific DataSource to understand its delta processing capabilities and limitations.
  
  
  
  Contact SAP Support:
  
  If the issue persists after checking the above points, consider reaching out to SAP support for further assistance.
  
  
  
  Related Information:
  
  Delta Processing Types: Understand the different types of delta processing (e.g., full, delta, and real-time) and how they apply to your DataSource.
  DataSource Activation: Familiarize yourself with the process of activating DataSources in SAP BW/4HANA or SAP BW systems.
  Transaction Codes: Use transaction codes like RSA1 for DataSource management and RSC3 for monitoring delta queues.
  
  By following these steps, you should be able to identify and resolve the RD185 error effectively.
