Hello *,
in my CAF application I'd like to read a product from SAP PLM. Within my Entity Service materialNumber is my custom key and therefore a corresponding operation exists: readByCustomKeys.
I map this operation to my External Service (Web service provided by XI).
As I can't test this operation directly with the Service Browser (deosn't appear there), I wrap my Entity Service with an Application Service where I use the readByCustomKeys operation from Entity Service.
Now when I test the Application Service operation I get the following error message in Service Browser:
ERROR. Invalid type value :
In XI I can see that there was no error and I got well defined XML data as response. So the problem must occur anywhere in the mapping back from External Service data to Entity Service attributes.
Wrong data type mapping can be excluded as I already tested this possibility.
Does anyone know what could be the reason?
Thanks for your answers and best regards
Joschi
