• What is the cause and solution for SAP error message RSAU027 - Characteristic value '&' for InfoObject '&' is not numerical ?

  The SAP error message RSAU027 indicates that there is an issue with a characteristic value in an InfoObject that is expected to be numerical but is not. This typically occurs in the context of data extraction or transformation processes in SAP BW (Business Warehouse) or SAP BI (Business Intelligence).
  Cause:
  
  Data Type Mismatch: The InfoObject is defined to hold numerical values (e.g., integers or decimals), but the data being loaded or processed contains non-numerical values (e.g., text, special characters).
  Data Quality Issues: The source data may have inconsistencies or errors, such as incorrect formatting or unexpected characters.
  Transformation Logic: If there are transformations applied to the data during the ETL (Extract, Transform, Load) process, they may not be correctly converting or validating the data types.
  
  Solution:
  
  Check Source Data: Review the source data for the characteristic value in question. Ensure that all values intended for the numerical InfoObject are indeed numerical and do not contain any non-numeric characters.
  Data Cleansing: If non-numerical values are found, cleanse the data by either correcting the values or filtering them out before loading them into SAP BW.
  Transformation Rules: If transformations are being applied, verify that they are correctly handling the data types. Ensure that any conversion functions are appropriately converting values to the expected numerical format.
  InfoObject Settings: Check the settings of the InfoObject in SAP BW. Ensure that it is correctly defined as a numerical type and that any relevant attributes or settings are configured properly.
  Error Handling: Implement error handling in your ETL process to catch and log such issues, allowing for easier troubleshooting in the future.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  Data Validation: Implement data validation checks in your ETL process to catch these types of errors early.
  Documentation: Review the documentation for the specific InfoObject and the data model to ensure compliance with expected data formats.
  
  By addressing the root cause of the error and ensuring that the data conforms to the expected formats, you can resolve the RSAU027 error and prevent it from occurring in the future.
