• What is the cause and solution for SAP error message RSAU726 - & error occurred in start routine for data target & ?

  The SAP error message RSAU726 typically indicates that there is an issue during the data loading process in SAP BW (Business Warehouse) or SAP BI (Business Intelligence). This error occurs specifically in the start routine of a data target, which is part of the data extraction and loading process.
  Cause of RSAU726 Error
  
  Data Quality Issues: The data being loaded may contain invalid or unexpected values that the start routine cannot handle.
  Coding Errors: If there is custom ABAP code in the start routine, there may be syntax errors or logical errors in the code.
  Data Type Mismatches: The data types of the source fields may not match the expected data types in the target data structure.
  Missing or Incorrect Configuration: The data target may not be properly configured, or there may be missing settings in the InfoPackage or transformation.
  Resource Limitations: Insufficient memory or other system resources can lead to failures during data processing.
  
  Solutions to RSAU726 Error
  
  Check Data Quality: Review the data being loaded for any inconsistencies or invalid values. Cleanse the data if necessary.
  Review Start Routine Code: If there is custom ABAP code in the start routine, check for any errors or exceptions. Debug the code to identify the exact point of failure.
  Validate Data Types: Ensure that the data types in the source and target match. Adjust the transformation rules if necessary.
  Configuration Review: Verify the configuration of the InfoPackage, transformation, and data target. Ensure that all necessary settings are correctly defined.
  Monitor System Resources: Check system logs and performance metrics to ensure that there are sufficient resources available for the data load process.
  Use Transaction RSMO: You can use transaction RSMO to monitor the data load process and identify any specific issues related to the data load.
  
  Related Information
  
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench), RSMO (Monitor Data Load), and RSPC (Process Chain) to manage and monitor data loads.
  SAP Notes: Check for relevant SAP Notes that may address specific issues related to the RSAU726 error. SAP Notes often provide patches or workarounds for known issues.
  Logs and Traces: Review the application logs (transaction SLG1) and short dumps (transaction ST22) for more detailed error messages that can provide additional context for troubleshooting.
  
  By following these steps, you should be able to identify the root cause of the RSAU726 error and implement a solution to resolve it.
