• What is the cause and solution for SAP error message C_008 - The request already exists in OLTP system ?

  The SAP error message C_008, which states "The request already exists in OLTP system," typically occurs during the data extraction or data loading processes, particularly when working with SAP BW (Business Warehouse) or during data transfer processes (DTP) from an OLTP (Online Transaction Processing) system to a BW system.
  Cause:
  The error usually arises due to one of the following reasons:
  
  
  Duplicate Request: The data request you are trying to load or process already exists in the target system. This can happen if the same data load is attempted multiple times without proper handling of existing requests.
  
  
  Data Transfer Process (DTP) Configuration: There may be issues with the DTP configuration that allow for duplicate requests to be generated.
  
  
  Request Management: The request might not have been properly deleted or managed in the system, leading to conflicts when trying to create a new request.
  
  
  Solution:
  To resolve the C_008 error, you can take the following steps:
  
  
  Check Existing Requests:
  
  Go to the relevant InfoProvider (e.g., InfoCube, DataStore Object) in the BW system and check for existing requests. You can do this through transaction codes like RSA1 (Data Warehousing Workbench) or RSD1 (InfoProvider Maintenance).
  If you find a duplicate request, you can either delete it or choose to load data into a different request.
  
  
  
  Adjust DTP Settings:
  
  Review the DTP settings to ensure that they are configured correctly. Check the "Data Target" settings and ensure that the "Request Handling" options are set appropriately to avoid duplicates.
  
  
  
  Use a New Request:
  
  If the existing request is valid and should not be deleted, consider using a new request for your data load. This can often be done by adjusting the settings in the DTP or the data load process.
  
  
  
  Monitor Load Processes:
  
  Ensure that your data load processes are monitored and managed properly to avoid overlapping requests. This can help prevent the occurrence of duplicate requests in the future.
  
  
  
  Check for Errors in Previous Loads:
  
  Sometimes, previous loads may not have completed successfully, leading to inconsistencies. Check for any errors in previous data loads and resolve them before attempting to load new data.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1, RSD1, and SM37 (for monitoring jobs) to manage and troubleshoot data loads effectively.
  SAP Notes: Check SAP Notes for any specific patches or updates related to this error message, as there may be known issues or fixes provided by SAP.
  Documentation: Review SAP documentation on data loading processes and DTP configurations for best practices and troubleshooting tips.
  
  By following these steps, you should be able to resolve the C_008 error and successfully manage your data requests in the SAP system.
