• What is the cause and solution for SAP error message RSDME185 - Error in INST/MERG due to inconsistent field mappings in D and M versions ?

  The SAP error message RSDME185 indicates that there is an inconsistency in field mappings between the Data (D) version and the Metadata (M) version of a DataStore Object (DSO) or InfoProvider. This error typically arises during the process of merging or installing data, where the system expects the field mappings to be consistent across the different versions.
  Cause:
  
  Inconsistent Field Mappings: The primary cause of this error is that the field mappings in the D version (the actual data version) do not match those in the M version (the metadata version). This can happen if changes were made to the structure of the DSO or InfoProvider without corresponding updates to the metadata.
  Changes in Data Structure: If fields were added, removed, or renamed in the D version without updating the M version, it can lead to inconsistencies.
  Transport Issues: If the D and M versions were transported separately, it might lead to mismatches if the transport order was not maintained correctly.
  
  Solution:
  To resolve the RSDME185 error, follow these steps:
  
  
  Check Field Mappings:
  
  Go to the DataStore Object or InfoProvider in question.
  Compare the field mappings in the D version and the M version.
  Ensure that all fields in the D version are correctly mapped to the corresponding fields in the M version.
  
  
  
  Adjust Mappings:
  
  If you find discrepancies, adjust the mappings in the M version to match those in the D version.
  You can do this by going to the Data Modeler or the relevant transaction code (like RSA1) and updating the field mappings.
  
  
  
  Re-activate the DSO/InfoProvider:
  
  After making the necessary adjustments, re-activate the DSO or InfoProvider to ensure that the changes take effect.
  
  
  
  Check for Transport Issues:
  
  If the issue arose due to transport, ensure that the transports are in the correct order and that all necessary objects have been transported together.
  
  
  
  Use Transaction RSD1:
  
  You can also use transaction RSD1 to check the structure of the DSO and ensure that it is consistent with the metadata.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes that might address this specific error or provide additional guidance.

  DataStore Object (DSO): A DSO is a type of InfoProvider in SAP BW that stores data in a way that allows for easy reporting and analysis.
  Metadata Version (M): This version contains the structure and definitions of the data, while the Data version (D) contains the actual data.
  SAP BW/BI: Understanding the architecture of SAP BW/BI can help in troubleshooting issues related to data modeling and InfoProviders.
  
  By following these steps, you should be able to resolve the RSDME185 error and ensure that your field mappings are consistent across the D and M versions.
