<LS>Superior Location</> or <LS>Reference Location</>. However, the
field may be changed due to inheritance if the superior object has been
selected for mass changes.

• What is the cause and solution for SAP error message EFH011 - Field &1 will not be changed directly; it might be changed by inheritance ?

  The SAP error message EFH011 indicates that a field (denoted as &1) cannot be changed directly because it is subject to inheritance. This typically occurs in the context of object-oriented programming in ABAP, particularly when dealing with classes and their attributes.
  Cause:
  The error arises when you attempt to modify a field that is inherited from a superclass or a base class. Inheritance in object-oriented programming means that a subclass inherits properties and methods from a superclass. In SAP ABAP, certain fields are designed to be read-only in subclasses to maintain the integrity of the inherited data.
  Solution:
  To resolve this error, you should consider the following approaches:
  
  
  Check Inheritance Structure: Review the class hierarchy to understand which class the field is inherited from. You can do this by checking the class definition in the ABAP Workbench (transaction SE80 or SE24).
  
  
  Use Setter Methods: If the field is intended to be modified, check if there are setter methods provided in the superclass. Use these methods to change the value of the field instead of trying to change it directly.
  
  
  Override Methods: If you need to change the behavior of the inherited field, consider overriding the relevant methods in the subclass. This allows you to implement custom logic while adhering to the inheritance rules.
  
  
  Redesign Class Structure: If the design allows, you might consider redesigning the class structure to avoid the need for direct modification of inherited fields. This could involve creating new fields in the subclass or using composition instead of inheritance.
  
  
  Consult Documentation: Review the SAP documentation or the specific class documentation to understand the intended use of the field and any constraints associated with it.
