• What is the cause and solution for SAP error message RSBC104 - Maximum request &1 (DTP &2) ?

  The SAP error message RSBC104, which states "Maximum request &1 (DTP &2)," typically occurs in the context of Data Transfer Processes (DTP) in SAP BW (Business Warehouse). This error indicates that the maximum number of requests that can be processed simultaneously has been exceeded.
  Cause:
  
  Concurrency Limit: SAP BW has a limit on the number of requests that can be processed at the same time. This limit is set to prevent system overload and ensure optimal performance.
  Long-running Requests: If there are long-running requests that are still in process, they may occupy slots in the queue, preventing new requests from being processed.
  Configuration Settings: The maximum number of requests can be configured in the system settings, and it may be set too low for the current workload.
  
  Solution:
  
  Check Running Requests: Use transaction code RSRT or RSMO to monitor the status of running requests. Identify any long-running or stuck requests and consider terminating them if they are not needed.
  Adjust Maximum Request Settings: If the system is consistently hitting the maximum request limit, consider increasing the limit. This can be done in the DTP settings or in the BW system configuration.
  Batch Processing: If possible, schedule DTPs to run in batches rather than all at once. This can help manage the load on the system.
  Optimize DTP Performance: Review the DTP settings and optimize them for better performance. This may include adjusting the data flow, reducing the volume of data being processed, or optimizing transformations.
  System Resources: Ensure that the system has adequate resources (CPU, memory, etc.) to handle the workload. If necessary, consider scaling up the infrastructure.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSMO (Monitor Data Transfer Processes), RSRT (Query Monitor), and RSA1 (Data Warehousing Workbench).
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or patches related to this error.
  Performance Monitoring: Regularly monitor system performance and request processing to proactively manage and prevent this error from occurring in the future.
  
  By following these steps, you should be able to resolve the RSBC104 error and improve the efficiency of your DTP processes in SAP BW.
