SOS_MAPPING154
- The attribute is not a reference in the defined superclass ?The SAP error message SOS_MAPPING154 indicates that there is an issue with the mapping of attributes in a class hierarchy, specifically that an attribute you are trying to reference in a subclass is not defined as a reference in the superclass. This typically occurs in the context of Object-Oriented Programming (OOP) in ABAP, particularly when dealing with class inheritance and attribute visibility.
Cause:
- Attribute Definition: The attribute you are trying to access in the subclass is not defined in the superclass. In OOP, subclasses can only access attributes that are defined in their superclass.
- Visibility: The attribute might be defined in the superclass but is not visible to the subclass due to its visibility modifier (e.g.,
PRIVATE
).- Incorrect Mapping: If you are using a mapping tool or framework, the mapping might be incorrectly set up, leading to this error.
Solution:
Check Superclass Definition: Ensure that the attribute you are trying to reference in the subclass is defined in the superclass. If it is not, you need to add it to the superclass.
Adjust Visibility: If the attribute is defined in the superclass but is marked as
PRIVATE
, consider changing its visibility toPROTECTED
orPUBLIC
so that it can be accessed by subclasses.Review Mapping Configuration: If you are using a mapping tool, check the configuration to ensure that the mappings are correctly set up and that the attributes are correctly referenced.
Code Review: Review the code in both the superclass and subclass to ensure that the inheritance structure is correctly implemented and that there are no typos or logical errors in the attribute names.
Documentation: Refer to the SAP documentation for Object-Oriented ABAP to understand the rules of inheritance and visibility, which can help clarify how attributes should be defined and accessed.
