SAP Error Message - Details

• Message type: E = Error

• Message class: 5AT - General Attribute Maintenance

• Message number: 109

• Message text: Attribute &1 cannot be redefined locally

What causes this issue?

The <DS:DE.OM_ATTRINH>inheritance logic</> does not allow for local
values for the attribute (inheritance logic 'I').

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

You can either delete the value for the superordinate (imparting)
object, or for the subordinate (inheriting) object. In either case,
consistency will be reestablished. Note, however, that changing the
imparting object could possibly affect other corresponding subordinate
objects.

• What is the cause and solution for SAP error message 5AT109 - Attribute &1 cannot be redefined locally ?

  The SAP error message 5AT109, which states "Attribute &1 cannot be redefined locally," typically occurs in the context of ABAP programming, particularly when dealing with class attributes in the Object-Oriented Programming (OOP) paradigm.
  Cause:
  This error arises when you attempt to redefine an attribute of a superclass in a subclass. In ABAP, attributes (or properties) that are defined in a superclass cannot be redefined in a subclass. This is because attributes are meant to maintain a consistent interface across the class hierarchy. 
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Remove the Redefinition: If you do not need to change the attribute in the subclass, simply remove the redefinition from the subclass.
  
  
  Use a Different Attribute Name: If you need a similar attribute in the subclass, you can define a new attribute with a different name in the subclass.
  
  
  Use Methods for Different Behavior: If the intention was to change the behavior associated with the attribute, consider overriding methods instead of redefining the attribute. You can create getter and setter methods in the subclass that provide the desired functionality.
  
  
  Check Class Hierarchy: Ensure that you are aware of the class hierarchy and the attributes defined in the superclass. This will help you avoid attempting to redefine attributes that are not allowed.
  
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP documentation on Object-Oriented Programming in ABAP for more details on class attributes and inheritance rules.
  SAP Community: You can search for discussions or similar issues on the SAP Community forums, where other developers may have encountered and resolved similar problems.
  Debugging: If you are unsure where the error is occurring, use the ABAP debugger to trace the execution and identify the point at which the error is triggered.
  
  By following these steps, you should be able to resolve the 5AT109 error and ensure that your ABAP code adheres to the principles of object-oriented design.
