• What is the cause and solution for SAP error message RSR_PE015 - Session &1 contains NULL values ?

  The SAP error message RSR_PE015 indicates that a session in the SAP BW (Business Warehouse) system contains NULL values, which can lead to issues during data processing or reporting. This error typically arises when the data being processed does not meet the expected criteria, particularly when NULL values are present in key fields that are required for the operation.
  Cause:
  
  NULL Values in Key Fields: The most common cause of this error is the presence of NULL values in key fields of the data being processed. This can occur during data extraction, transformation, or loading (ETL) processes.
  Data Source Issues: The data source may have records with missing values, which can lead to NULLs being passed into the BW system.
  Incorrect Data Modeling: The data model may not be set up correctly, leading to situations where NULL values are not handled properly.
  Transformation Logic: The transformation rules applied during data loading may not account for NULL values, resulting in them being propagated into the session.
  
  Solution:
  
  Data Cleansing: Review the source data for NULL values and clean the data before loading it into the BW system. This may involve filling in missing values or removing records with NULLs.
  Modify Transformation Logic: Adjust the transformation rules in the Data Transfer Process (DTP) to handle NULL values appropriately. You can use functions to replace NULLs with default values or filter them out.
  Check Data Source: Ensure that the data source is providing complete and accurate data. If necessary, modify the extraction logic to ensure that NULL values are not included.
  Session Management: If the session is already created and contains NULL values, you may need to delete the session and re-run the data load after addressing the NULL issues.
  Error Handling: Implement error handling in your ETL processes to catch and manage NULL values before they cause issues in the BW system.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like RSA1 (Data Warehousing Workbench) to analyze and manage data models and processes.
  Monitoring: Use transaction RSMO to monitor data loads and check for errors related to NULL values.
  Documentation: Refer to SAP documentation for best practices on data modeling and handling NULL values in BW.
  
  By addressing the root causes of NULL values and implementing appropriate solutions, you can resolve the RSR_PE015 error and ensure smoother data processing in your SAP BW environment.
