• What is the cause and solution for SAP error message RSR_PE111 - Null_Handler: Number of rows with null values in column &1 / &2 : &3 ?

  The SAP error message RSR_PE111, which indicates a "Null_Handler" issue, typically arises in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when there are null values in a specific column of a dataset. The message provides details about the number of rows that contain null values in the specified column.
  Cause:
  The error message RSR_PE111 is triggered when the data processing logic encounters null values in a column that is expected to contain valid data. This can happen due to various reasons, such as:
  
  Data Extraction Issues: During the data extraction process from the source system, some records may not have been populated correctly, leading to null values.
  Transformation Logic: If there are transformations applied to the data that do not handle null values appropriately, this can result in nulls being passed through to the final dataset.
  Data Loading Problems: Issues during the data loading process into the InfoProvider can also lead to null values being present.
  Inconsistent Data: The source data may inherently contain null values due to business processes or data entry errors.
  
  Solution:
  To resolve the RSR_PE111 error, you can take the following steps:
  
  
  Identify the Source of Null Values:
  
  Check the source data to identify why null values are present. This may involve reviewing the data extraction logic or the source system itself.
  
  
  
  Modify Transformation Logic:
  
  If the null values are a result of transformation logic, consider modifying the transformation rules to handle nulls appropriately. This could involve using default values or filtering out nulls.
  
  
  
  Data Cleansing:
  
  Perform data cleansing on the source data to ensure that null values are addressed before they are loaded into the BW system. This may involve updating records in the source system or applying cleansing rules during the ETL (Extract, Transform, Load) process.
  
  
  
  Adjust InfoObject Settings:
  
  Review the settings of the InfoObject in BW to ensure that it is configured to handle null values correctly. This may include setting default values or adjusting aggregation settings.
  
  
  
  Check Data Load Process:
  
  Review the data load process to ensure that it is functioning correctly and that there are no errors during the loading of data into the InfoProvider.
  
  
  
  Use Queries to Handle Nulls:
  
  If the null values are acceptable in certain contexts, consider modifying the queries or reports to handle nulls gracefully, such as by using COALESCE or similar functions to replace nulls with default values.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling null values in BW.
  Documentation: Review SAP BW documentation for best practices on data modeling, ETL processes, and handling null values.
  Community Forums: Engage with SAP community forums or support channels for insights from other users who may have encountered similar issues.
  
  By following these steps, you should be able to identify the root cause of the null values and implement a solution to resolve the RSR_PE111 error.
