• What is the cause and solution for SAP error message UJR_EXCEPTION029 - Error occurs when writing to cube; Keyfigure must be less than 14 digits ?

  The SAP error message UJR_EXCEPTION029 typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when there is an attempt to write data to a cube, and the key figure being processed exceeds the allowed digit limit. Specifically, the error indicates that the key figure must be less than 14 digits.
  Cause:
  
  Data Type Limitation: The key figure in question is likely defined as a numeric type that has a maximum limit of 14 digits. If the data being loaded into this key figure exceeds this limit, the error will be triggered.
  Data Source Issue: The source data being extracted may contain values that are larger than what the target key figure can accommodate.
  Transformation Logic: There may be transformation rules or calculations that inadvertently produce values exceeding the 14-digit limit.
  
  Solution:
  
  Check Data Values: Review the data being loaded into the cube. Identify any key figures that exceed the 14-digit limit and determine if they can be adjusted or truncated.
  Adjust Data Type: If possible, consider changing the data type of the key figure in the InfoObject definition to accommodate larger values. However, this may require a redesign of the data model and should be done with caution.
  Data Transformation: Modify the transformation logic to ensure that the values being written to the cube do not exceed the 14-digit limit. This could involve rounding, truncating, or applying business rules to limit the size of the data.
  Error Handling: Implement error handling in your data load process to catch and log these errors, allowing for easier troubleshooting in the future.
  Testing: After making changes, perform thorough testing to ensure that the data loads correctly without triggering the error.
