  The SAP error message SADL_ENTITY_RUNTIME031 indicates that a query operation on a specific element of an entity is not implemented. This typically occurs in the context of SAP's Service Adaptation Definition Language (SADL), which is used for building OData services and managing data access in SAP applications.
  Cause:
  
  Unsupported Operation: The specific query operation you are trying to perform on the entity is not supported. This could be due to the fact that the element you are querying does not have the necessary implementation in the backend.
  Model Definition Issues: There may be issues in the way the entity or its elements are defined in the SADL model. If the model does not correctly define the operations that can be performed on the entity, you may encounter this error.
  Data Source Limitations: The underlying data source may not support the requested operation. For example, if the data source is a database view that does not allow certain types of queries, this error may occur.
  
  Solution:
  
  Check Entity Definition: Review the definition of the entity and its elements in the SADL model. Ensure that the operations you are trying to perform are supported and correctly defined.

  Consult Documentation: Refer to the SAP documentation for SADL and the specific entity you are working with. This can provide insights into what operations are supported and how to properly define them.
