• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED229 - Parameter '&1' on function '&2' is not primitive type based ?

  The SAP error message /IWBEP/CM_V4_MED229 indicates that there is an issue with the parameter type in a function module or method that is being called in an OData service. Specifically, the error message states that the parameter &1 on function &2 is not of a primitive type. In the context of OData services, primitive types refer to basic data types such as String, Int, Boolean, etc.
  
  Cause:
  
  Non-Primitive Data Type: The parameter in question is likely defined as a complex type or a structure rather than a primitive type. OData services expect parameters to be of primitive types for certain operations, especially when dealing with query parameters or function imports.
  Incorrect Mapping: There may be an issue with how the parameter is mapped in the OData service definition. If the parameter is expected to be a primitive type but is defined as a complex type in the service, this error will occur.
