• What is the cause and solution for SAP error message UJJ_EXCEPTION143 - Length reduction of Additional Property &1 is not allowed ?

  The SAP error message UJJ_EXCEPTION143 with the description "Length reduction of Additional Property &1 is not allowed" typically occurs in the context of SAP applications that involve data modeling, particularly when working with additional properties in the context of SAP HANA or SAP BW.
  Cause:
  This error arises when there is an attempt to reduce the length of an additional property (like a field or attribute) that has already been defined in a data model. In SAP, once a property is defined with a certain length, it cannot be reduced because it may lead to data loss or inconsistencies in the data model.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Definition: Review the definition of the additional property that is causing the error. Ensure that you are not trying to change its length to a smaller value.
  
  
  Modify the Length: If you need to change the length of the property, you should increase it instead of reducing it. This can be done in the data model or the relevant configuration settings.
  
  
  Recreate the Property: If you need to change the length significantly, consider deleting the existing property and creating a new one with the desired length. Be cautious with this approach, as it may affect existing data or references.
  
  
  Review Dependencies: Check if there are any dependencies or references to the property in other parts of the model or application. Ensure that changing the property will not break any existing functionality.
  
  
  Consult Documentation: Refer to the SAP documentation or help resources for specific guidelines on handling additional properties in your version of SAP.
  
  
  Testing: After making changes, thoroughly test the data model to ensure that it functions correctly and that the error does not reoccur.
