• What is the cause and solution for SAP error message UJO_WB_EXCEPTION029 - Error occurs when writing to cube; Keyfigure must be less than 14 digits ?

  The SAP error message UJO_WB_EXCEPTION029 typically occurs when there is an attempt to write data to a cube, and one of the key figures exceeds the allowed limit of 14 digits. This is a common issue in SAP BW (Business Warehouse) or SAP HANA environments where data types and their limits are strictly enforced.
  Cause:
  The error is caused by one of the following:
  
  Data Type Limitations: The key figure in question is defined as a numeric type that can only hold a maximum of 14 digits. If the data being written exceeds this limit, the error will be triggered.
  Data Source Issues: The source data being loaded into the cube may contain values that are larger than the allowed limit for the key figure.
  Transformation Logic: If there are transformations or calculations applied to the data before it is written to the cube, these may inadvertently produce values that exceed the limit.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Key Figure Definition:
  
  Go to the InfoObject definition for the key figure in question and verify its data type and length. Ensure that it is set to accommodate the expected range of values.
  
  
  
  Data Validation:
  
  Review the source data being loaded into the cube. Check for any values that exceed 14 digits and either correct them or filter them out before loading.
  
  
  
  Transformation Logic Review:
  
  If you are using transformations, check the logic to ensure that calculations do not produce values exceeding the 14-digit limit. Adjust the logic as necessary.
  
  
  
  Data Type Adjustment:
  
  If it is feasible and appropriate for your business case, consider changing the data type of the key figure to a larger numeric type (e.g., from DEC to DECIMAL with a higher precision) to accommodate larger values.
  
  
  
  Error Handling:
  
  Implement error handling in your data load process to catch and log any values that exceed the limit, allowing for easier troubleshooting in the future.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to this error message for any specific patches or updates that may address the issue.
  Documentation: Review SAP BW or HANA documentation for best practices on data modeling and key figure definitions.
  Testing: After making changes, perform thorough testing to ensure that the data loads successfully without triggering the error.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to prevent it from occurring in the future.
