  The SAP error message CM_EHFND_PRPTY_COMN022 indicates that there is a type mismatch when trying to assign a root type to a property in your SAP application. This typically occurs in the context of SAP's Enterprise Services or when working with the SAP Cloud Platform, particularly in scenarios involving OData services or data models.
  Cause:
  The error arises when:
  
  You are trying to assign a data type (root type) that is not compatible with the expected type of the property.
  The property definition in your data model does not match the data type you are trying to assign.
  There may be a misconfiguration in the metadata or the data model definitions.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Data Model Definitions:
  
  Review the data model where the property is defined. Ensure that the root type you are trying to assign is compatible with the property type.
  Verify that the property is defined correctly in the metadata and that it matches the expected data type.
  
  
  
  Adjust Type Assignments:
  
  If you are using a custom type, ensure that it is correctly defined and that it inherits from the appropriate base type.
  If necessary, modify the type of the property to match the root type you are trying to assign.
  
  
  
  Review OData Service:
  
  If this error occurs while consuming an OData service, check the service metadata (usually accessible via the $metadata endpoint) to ensure that the types are correctly defined and aligned.
  
  
  
  Check for Updates:
