• What is the cause and solution for SAP error message RSM2171 - DM inflow check for DTA &1. Only &2 further datamarted requests found. ?

  The SAP error message RSM2171 typically relates to issues with Data Mart (DM) inflow checks in the context of SAP BW (Business Warehouse). This error indicates that there is a problem with the data flow into a Data Mart, specifically that the system has detected an inconsistency or issue with the data requests.
  Cause:
  The error message "DM inflow check for DTA &1. Only &2 further datamarted requests found." suggests that the system is expecting a certain number of data requests to be present for a specific Data Transfer Process (DTP) but has found fewer than expected. This can occur due to several reasons:
  
  Missing Data Requests: The expected data requests for the DTP may not have been created or may have been deleted.
  Data Transfer Issues: There may have been issues during the data transfer process, leading to incomplete or failed requests.
  Configuration Issues: The DTP or Data Mart may not be configured correctly, leading to mismatches in expected data flow.
  Data Source Issues: The source system may not be providing the expected data, or there may be issues with the data extraction process.
  
  Solution:
  To resolve the RSM2171 error, you can follow these steps:
  
  
  Check Data Requests: Verify the data requests associated with the DTP. Ensure that the expected requests are present and have been successfully executed.
  
  Go to the Data Warehousing Workbench (transaction RSA1) and check the DTP for the relevant InfoProvider.
  Look for any requests that are in error status and analyze the logs for those requests.
  
  
  
  Re-run Data Transfer: If you find that requests are missing or have failed, try re-running the data transfer process.
  
  You can do this by executing the DTP again and monitoring the process for any errors.
  
  
  
  Review DTP Configuration: Check the configuration of the DTP to ensure that it is set up correctly.
  
  Ensure that the source and target InfoProviders are correctly defined and that the transformation rules are appropriate.
  
  
  
  Check Source System: Investigate the source system for any issues that may be affecting data extraction.
  
  Ensure that the data is available and that there are no connectivity issues between the source and the BW system.
  
  
  
  Monitor Process Chains: If the DTP is part of a process chain, check the process chain for any failures or issues that may have occurred prior to the DTP execution.
  
  
  Consult Logs: Review the logs for the DTP execution and any related processes to identify specific errors or warnings that may provide more context on the issue.
  
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench), RSMO (Monitor Data Transfer), and RSPC (Process Chain Maintenance) to monitor and manage data flows.
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide additional troubleshooting steps related to this error.
  Documentation: Refer to SAP BW documentation for best practices on managing DTPs and Data Marts.
  
  By following these steps, you should be able to identify the root cause of the RSM2171 error and implement a solution to resolve it.
