• What is the cause and solution for SAP error message SOS_MAPPING852 - A dictionary object was used in the superclass and subclass ?

  The SAP error message SOS_MAPPING852 indicates that there is an issue with the mapping of dictionary objects in the context of class inheritance. This error typically arises when a superclass and its subclass are both trying to use the same dictionary object, which can lead to conflicts or inconsistencies in the data structure.
  Cause:
  
  Inheritance Issues: The error often occurs when a subclass is trying to redefine or use a dictionary object that has already been defined in its superclass. This can lead to ambiguity in how the dictionary object is accessed or modified.
  Data Structure Conflicts: If both the superclass and subclass are trying to manipulate the same dictionary object without proper encapsulation or handling, it can lead to unexpected behavior or errors.
  Mapping Configuration: The error may also arise from incorrect mapping configurations in the context of data transfer or transformation processes.
  
  Solution:
  
  Review Class Definitions: Check the definitions of both the superclass and subclass to ensure that dictionary objects are not being redefined unnecessarily. If a dictionary object is needed in both classes, consider using a shared or static dictionary object.
  Encapsulation: Use encapsulation to manage access to dictionary objects. This can involve creating getter and setter methods to control how the dictionary is accessed and modified.
  Refactor Code: If the design allows, refactor the code to avoid using the same dictionary object in both the superclass and subclass. Instead, consider passing the dictionary as a parameter or using composition instead of inheritance.
  Check Mapping Configurations: If the error is related to data mapping, review the mapping configurations to ensure that they are correctly set up and do not conflict with each other.
