• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED173 - Currency property cannot be set: property '&1' has invalid conv. type ?

  The SAP error message /IWBEP/CM_V4_MED173 indicates that there is an issue with setting a currency property in an OData service. The error message specifically states that the property has an invalid conversion type, which typically means that the data type or format of the currency property being used is not compatible with what is expected by the OData service.
  Cause:
  
  Invalid Data Type: The currency property may be defined with an incorrect data type in the data model. For example, it might be defined as a string instead of a decimal or a currency type.
  Incorrect Mapping: There may be a mismatch between the data type in the backend (e.g., ABAP structure) and the OData service definition.
  Configuration Issues: The OData service might not be properly configured to handle currency types, or there may be issues in the service metadata.
  Missing Currency Code: If the currency property is expected to include a currency code (like 'USD', 'EUR'), and it is missing or incorrectly formatted, this can lead to the error.
  
  Solution:
  
  Check Data Model: Review the data model in the backend (e.g., ABAP Dictionary) to ensure that the currency property is defined with the correct data type (e.g., CURR or DEC for currency values).
  Update OData Service: If there are changes in the backend data model, regenerate the OData service to ensure that the service reflects the correct data types.
  Review Service Metadata: Check the service metadata (e.g., using the /IWBEP/REG_SERVICE transaction) to ensure that the currency property is correctly defined and mapped.
  Test with Sample Data: Use sample data to test the OData service and ensure that the currency values are being passed correctly, including the currency code if required.
  Debugging: If the issue persists, consider debugging the OData service to trace where the conversion is failing and to identify the exact point of failure.
  
  Related Information:
