  The SAP error message SADL_GW_DT_SB_API025 typically indicates a type mismatch in the data model when using the SAP Data Access Layer (SADL) for OData services. This error occurs when the type of an element in the data structure does not match the expected type defined in the project.
  Cause:
  
  Type Mismatch: The type of the element (e.g., a field in a structure or entity) does not match the type defined in the corresponding project or data model.
  Changes in Data Model: If there have been recent changes to the data model or the underlying database structure, it may lead to inconsistencies.
  Incorrect Mapping: The mapping between the data model and the OData service may not be correctly defined, leading to type discrepancies.
  
  Solution:
  
  Check Data Types: Verify the data types of the elements in the data model and ensure they match the expected types in the project. This can be done by checking the definitions in the ABAP Dictionary (SE11) or the relevant data model.
  Update Project: If there have been changes to the underlying data structure, ensure that the project is updated accordingly. This may involve regenerating the OData service or reactivating the project.
  Regenerate OData Service: If the data model has been modified, regenerate the OData service to ensure that the changes are reflected in the service definition.
  Check Annotations: Ensure that any annotations or metadata definitions are correctly defined and correspond to the expected types.
  Debugging: If the issue persists, consider debugging the OData service to trace where the type mismatch occurs. This may involve checking the implementation of the service and the data retrieval logic.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), and SEGW (Gateway Service Builder) to check and modify data structures and OData services.
