How To Fix UAS109 - Field '&1' has different visibility from higher-level field '&2'

SAP Error Message - Details

• Message type: E = Error

• Message class: UAS -

• Message number: 109

• Message text: Field '&1' has different visibility from higher-level field '&2'

What causes this issue?

When an attribute group is assigned to an object type, the units or
compound characteristics that belong to the fields of the attribute
group must have the same visibility as the field.

System Response

The structures cannot be saved or generated before this inconsistency
has been resolved.

How to fix this error?

Make sure that all fields have the same setting in the 'Transient'
column. Adjust the field catalogs of the attribute groups appropriately
for this.

• What is the cause and solution for SAP error message UAS109 - Field '&1' has different visibility from higher-level field '&2' ?

  The SAP error message UAS109 indicates that there is a visibility mismatch between a field defined at a lower level and a field defined at a higher level in the data model. This typically occurs in the context of ABAP Dictionary objects, such as structures or tables, where fields are defined with different visibility attributes (e.g., public, protected, or private).
  Cause:
  The error arises when:
  
  A field in a lower-level structure or table is defined with a different visibility than the corresponding field in a higher-level structure or table.
  This can happen during inheritance or when using interfaces, where the visibility of fields must be consistent across the hierarchy.
  
  Solution:
  To resolve the UAS109 error, you can take the following steps:
  
  
  Identify the Fields: Check the field definitions for both the lower-level field (&1) and the higher-level field (&2). You can do this by navigating to the Data Dictionary (SE11) and examining the relevant structures or tables.
  
  
  Align Visibility: Ensure that the visibility of the lower-level field matches that of the higher-level field. This may involve:
  
  Changing the visibility of the lower-level field to match the higher-level field.
  If the higher-level field is public, the lower-level field should also be public.
  If the higher-level field is protected, the lower-level field should also be protected.
  
  
  
  Check Inheritance: If you are using inheritance, ensure that the derived class or structure correctly implements the visibility of the base class or structure.
  
  
  Recompile: After making the necessary changes, recompile the affected objects to ensure that the changes take effect.
  
  
  Test: Run the program or transaction that triggered the error to confirm that the issue has been resolved.
  
  
  Related Information:
  
  ABAP Dictionary: Understanding how fields are defined in the ABAP Dictionary is crucial for resolving visibility issues.
  Object-Oriented Programming in ABAP: Familiarity with concepts of inheritance and visibility in object-oriented programming can help in understanding how these errors occur.
  SAP Notes: Check SAP Notes for any specific guidance or patches related to this error message, as there may be updates or known issues that provide additional context.
  
  By following these steps, you should be able to resolve the UAS109 error and ensure that your data model is correctly defined.
