• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED172 - Conv. exit cannot be set on prop. '&1': complex type '&2' is dict.-based ?

  The SAP error message /IWBEP/CM_V4_MED172 indicates that there is an issue with the conversion exit for a property in an OData service. Specifically, the error states that the conversion exit cannot be set on a property because the property is of a complex type that is dictionary-based.
  Cause:
  
  Complex Type: The property in question is defined as a complex type in the OData service. Complex types are structures that can contain multiple properties, and they are not simple data types (like string, integer, etc.).
  Dictionary-Based: The error message indicates that the complex type is dictionary-based, meaning it is defined in a way that does not allow for a conversion exit to be applied directly to it. Conversion exits are typically used for simple types to convert data formats (e.g., date formats, currency formats).
  
  Solution:
  
  Review the Data Model: Check the definition of the complex type in the OData service. Ensure that the properties within the complex type are defined correctly and that you are not trying to apply a conversion exit to the entire complex type.
  Adjust the Property Definition: If you need to apply a conversion exit, consider applying it to individual properties within the complex type rather than the complex type itself.
  Modify the OData Service: If necessary, modify the OData service implementation to handle the complex type appropriately without attempting to apply a conversion exit at the complex type level.
  Check for Updates: Ensure that you are using the latest version of the SAP Gateway and related components, as updates may include fixes or improvements related to OData services.
  
  Related Information:
  
  OData Services: Understand how OData services work in SAP and the difference between simple and complex types.
  Conversion Exits: Familiarize yourself with how conversion exits are defined and used in SAP, particularly in the context of OData services.
  SAP Documentation: Refer to the official SAP documentation for OData services and the specific error message for more detailed guidance and examples.
  
  If the issue persists after following these steps, consider reaching out to SAP support or consulting with an SAP expert who can provide more tailored assistance based on your specific implementation.
