SOS_MAPPING153
- The attribute is a reference in the defined superclass ?The SAP error message SOS_MAPPING153 indicates that there is an issue with the mapping of attributes in a class hierarchy, specifically when dealing with superclass and subclass relationships. This error typically arises in the context of Object-Oriented Programming (OOP) in ABAP, particularly when you are trying to map or access attributes that are defined in a superclass from a subclass.
Cause:
The error occurs when:
- You are trying to redefine an attribute in a subclass that is already defined in the superclass.
- The attribute in the subclass is not correctly mapped or is being referenced incorrectly.
- There may be inconsistencies in the class definitions or inheritance structure.
Solution:
To resolve the SOS_MAPPING153 error, you can take the following steps:
Check Class Definitions: Review the definitions of both the superclass and subclass. Ensure that the attributes are correctly defined and that you are not trying to redefine an attribute in the subclass that already exists in the superclass.
Use Proper Inheritance: If you need to use an attribute from the superclass, ensure that you are accessing it correctly in the subclass. You should not redefine it unless you intend to override it.
Mapping Configuration: If this error occurs in the context of a mapping configuration (e.g., in a data model or transformation), ensure that the mapping is correctly set up to reference the superclass attributes.
Check for Typographical Errors: Sometimes, simple typographical errors in attribute names can lead to this error. Double-check the spelling and case sensitivity of the attribute names.
Review Access Modifiers: Ensure that the access modifiers (public, protected, private) are correctly set for the attributes in both the superclass and subclass. If an attribute is private in the superclass, it cannot be accessed directly in the subclass.
Debugging: If the issue persists, consider using debugging tools to trace the execution and see where the mapping is failing.
