• What is the cause and solution for SAP error message SOS_MAPPING152 - The attribute is specified in the defined superclass as read-only ?

  The SAP error message SOS_MAPPING152 indicates that there is an issue with the mapping of attributes in a class hierarchy, specifically that an attribute is defined as read-only in the superclass. This typically occurs in the context of SAP's ABAP programming or when working with Business Object Processing Framework (BOPF) or similar object-oriented programming paradigms in SAP.
  Cause:
  The error arises when:
  
  An attribute in a subclass is being attempted to be modified or set, but it is defined as read-only in the superclass.
  The mapping or data model is trying to write to an attribute that is not allowed to be changed due to its read-only status.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Superclass Definition:
  
  Review the definition of the superclass where the attribute is defined. Confirm that the attribute is indeed marked as read-only.
  
  
  
  Modify the Subclass Logic:
  
  If you are trying to set or modify the attribute in the subclass, you need to remove that logic since the attribute is read-only. Instead, you should only read the value of the attribute.
  
  
  
  Consider Design Changes:
  
  If the attribute needs to be writable in the subclass, consider redesigning the class hierarchy. You may need to change the attribute definition in the superclass to allow writing, but be cautious as this may affect other parts of the application.
  
  
  
  Use Alternative Attributes:
  
  If the read-only attribute is not suitable for your needs, consider using a different attribute that is writable or create a new attribute in the subclass that can hold the necessary data.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or the specific module documentation for any additional guidelines on handling read-only attributes.
