  The SAP error message SOS_MAPPING826, which states "Attribute &: Wrong typing category in Class Builder," typically occurs when there is a mismatch in the data types or attributes defined in the class or interface in the Class Builder (transaction code SE24 or SE80). This error can arise during the definition of attributes, methods, or when trying to map data types in the class.
  Cause:
  
  Data Type Mismatch: The attribute you are trying to define or use has a data type that is not compatible with the expected type. For example, you might be trying to assign a string to an integer attribute.
  Incorrect Attribute Definition: The attribute may have been defined with an incorrect typing category (e.g., trying to use a reference type where a value type is expected).

  Invalid Mapping: If you are using a mapping or transformation that does not align with the expected data types, this error can occur.
  
  Solution:
  
  Check Attribute Definitions: Go to the Class Builder and review the definitions of the attributes. Ensure that the data types are correctly defined and compatible with their intended use.
  Correct Data Types: If you find any mismatches, correct the data types of the attributes to ensure they align with the expected types.
  Review Inheritance: If your class is inheriting from another class, check the attributes in the superclass to ensure there are no conflicts or mismatches.
  Recheck Mappings: If you are using mappings, ensure that the source and target data types are compatible. Adjust the mappings as necessary.
  Activate the Class: After making changes, make sure to activate the class to apply the changes.
