• What is the cause and solution for SAP error message UJA_EXCEPTION086 - Cannot decrease the property size of &1 ?

  The SAP error message UJA_EXCEPTION086 with the description "Cannot decrease the property size of &1" typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when there is an attempt to change the size of a property (characteristic) in a way that is not allowed. This can happen during data modeling or when trying to adjust the properties of InfoObjects.
  Cause:
  
  Property Size Change: The error is triggered when there is an attempt to decrease the size of a characteristic property (e.g., changing a field length from 20 to 10 characters) that already contains data exceeding the new size limit.
  Existing Data: If there are existing records in the InfoObject that have values longer than the new size, SAP will not allow the change to prevent data loss or truncation.
  Data Model Dependencies: The characteristic may be used in various data models, queries, or reports, and changing its size could lead to inconsistencies.
  
  Solution:
  
  
  Check Existing Data: Before attempting to change the size of a property, check the existing data in the InfoObject to ensure that no values exceed the new size limit.
  
  You can use transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser) to inspect the data.
  
  
  
  Adjust Data: If there are values that exceed the new size, you will need to either:
  
  Truncate or modify the existing data to fit the new size.
  Delete or archive records that are no longer needed.
  
  
  
  Change Property Size: Once you have ensured that all existing data complies with the new size, you can proceed to change the property size in the InfoObject.
  
  Use transaction RSD1 to access the InfoObject and make the necessary adjustments.
  
  
  
  Re-activate InfoObject: After making changes, you may need to re-activate the InfoObject to ensure that the changes take effect.
  
  
  Check Dependencies: Review any dependent objects (like queries, transformations, etc.) that might be affected by the change and adjust them accordingly.
  
  
  Related Information:
