How To Fix EU511 - Object & is part of the Basis interface; further development not allowed

EU511 - Overview

• Message type: E = Error

• Message class: EU - Development Environment

• Message number: 511

• Message text: Object & is part of the Basis interface; further development not allowed

What causes this issue?

Object &V1& is to be processed, but it is frozen. It is either part of a
released interface or released itself (in the case of function modules).
Object &V1&, therefore, may only be processed as a compatible object.

System Response

Operations that would cause an incompatible change will be refused.
Incompatible changes include, in particular, deleting frozen objects or
subobjects.
Objects that contain a call interface (function modules or methods) are
only allowed to have optional input, changing, or table parameters added
to them, in addition to output parameters. Adding further exceptions or
changing existing parameters is not allowed.
In the case of non-final classes, adding methods is not allowed either
because of the inheritance problems involved; however, implementing an
additional interface is allowed.

How to fix this error?

In justified cases, incompatible changes can be approved by QM and
interface experts (enhanced HOTPACKEXC exception procedures).

• What is the cause and solution for SAP error message EU511 - Object & is part of the Basis interface; further development not allowed ?

  The SAP error message EU511 indicates that the object you are trying to modify or develop is part of the Basis interface, and further development or changes to this object are not allowed. This is a protective measure implemented by SAP to ensure the integrity and stability of the core system components.
  
  Cause:
  
  Protected Objects: The object in question is a standard SAP object that is part of the Basis layer, which includes core functionalities and interfaces. SAP restricts modifications to these objects to prevent issues that could arise from custom changes.
  Transport Layer Restrictions: The object may be locked in the transport layer, preventing any changes or enhancements.
  Development Class: The object may belong to a development class that is marked as "SAP" or "Standard," which restricts modifications.
  
  
  Solution:
  
  
  Use Enhancements: Instead of modifying the standard object directly, consider using enhancement techniques provided by SAP, such as:
  
  User Exits: These allow you to add custom code
