• What is the cause and solution for SAP error message UJO_WB_EXCEPTION028 - Keyfigure (Signeddata) &1 is not a number or may have overflowed ?

  The SAP error message UJO_WB_EXCEPTION028 indicates that there is an issue with a key figure, specifically that the value for the key figure (in this case, "Signeddata") is either not a number or has overflowed. This typically occurs in the context of data processing or reporting within SAP BW (Business Warehouse) or similar environments.
  Causes:
  
  Non-numeric Data: The key figure may contain non-numeric values (e.g., text or special characters) that cannot be processed as numbers.
  Overflow: The value of the key figure exceeds the maximum limit that can be stored in the data type defined for it. For example, if the key figure is defined as an integer and the value exceeds the maximum integer limit.
  Data Type Mismatch: There may be a mismatch between the expected data type of the key figure and the actual data being processed.
  Data Extraction Issues: Problems during data extraction from the source system may lead to corrupted or invalid data being loaded into the key figure.
  
  Solutions:
  
  Data Validation: Check the source data for the key figure "Signeddata" to ensure that all values are numeric. You can use transaction codes like SE16 or SE11 to inspect the underlying data.
  Data Type Check: Verify the data type defined for the key figure in the InfoObject settings. Ensure that it is appropriate for the range of values you expect.
  Adjust Data Load: If the data is being loaded from a source system, review the extraction and transformation logic to ensure that it correctly handles numeric values and does not introduce non-numeric data.
  Error Handling: Implement error handling in your data processing logic to catch and log instances where non-numeric values or overflows occur, allowing for easier troubleshooting.
  Data Cleansing: If non-numeric values are found, you may need to cleanse the data before loading it into the key figure. This could involve converting values to numeric types or removing invalid entries.
  Increase Data Type Size: If overflow is the issue, consider changing the data type of the key figure to a larger type (e.g., from integer to decimal) if that aligns with your business requirements.
