• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED059 - Parameter '&1' is EDM-based ?

  The SAP error message /IWBEP/CM_V4_MED059 Parameter '&1' is EDM-based typically occurs in the context of SAP Gateway and OData services. This error indicates that a parameter in your OData service is defined as EDM (Entity Data Model) based, but it is being used in a way that is not compatible with its definition.
  Cause:
  
  EDM-based Parameter: The parameter in question is defined in the OData service as an EDM type, which means it is expected to follow certain rules and formats defined by the Entity Data Model.
  Incorrect Usage: The error can occur if the parameter is being passed in a way that does not conform to its EDM definition. This could be due to incorrect data types, missing values, or improper formatting.
  Service Definition Issues: There may be issues in the service definition or the way the service is being called, such as incorrect URL parameters or query options.
  
  Solution:
  
  Check Parameter Definition: Review the OData service definition in the SAP Gateway Service Builder (transaction code SEGW) to ensure that the parameter is correctly defined as EDM-based.
  Validate Input Data: Ensure that the data being passed to the parameter matches the expected EDM type. For example, if the parameter is expected to be a string, ensure that you are not passing a number or an object.
  Review Service Call: Check the way the OData service is being called. Ensure that the URL and query parameters are correctly formatted and that all required parameters are included.
  Debugging: If you have access to the backend, you can debug the OData service to see how the parameters are being processed and identify where the mismatch occurs.
  Consult Documentation: Refer to the SAP documentation for OData services and EDM to understand the expected formats and types for the parameters you are working with.
  
  Related Information:
  
  OData Protocol: Understanding the OData protocol and how it interacts with SAP systems can help in troubleshooting issues related to service calls.
  SAP Gateway: Familiarize yourself with SAP Gateway concepts, as this is the framework that handles OData services in SAP.
  EDM Types: Review the different EDM types (e.g., String, Int32, Boolean) and their constraints to ensure compliance when passing parameters.
