I developed a little (working) Web-Service in SAP. It demands a Import Parameter and Responses an Export Parameter. The Web-Service is reached by an basicHttp Request from C#. As the next Step I now want to pass binary data (Type x255) from SAP as the Export Parameter. My Question is now how do I know which C# Datatype can Contain these Data.

Also: Is there a way to pass a whole (lokal-) Table as Export Parameter?

    I would suggest you try and find out how you can get SAP to return something like JSON or XML (it's a fair bet that it will support XML I guess) - aside from this you should not return those stupid SAP tables as is even if the poor fool that has to use your service will somehow be able to make sense of this mess Commented Sep 17, 2015 at 9:37
  • Ok I will cross the Table return option of the list :). But does a SOAP Requests not always return its Data as XML? Commented Sep 17, 2015 at 9:41

    yes (I think ... SOAP kindof died a cruel death so I try hard to not remember it) - but you did not mention SOAP at first - if it is SOAP than chances are high that you can just use the "WebReference" stuff in VS and don't have to think about any mapping at all - having said this most Hipsters prefer to use JSON ;) (and REST of course) Commented Sep 17, 2015 at 9:52

Yes it is possible. All SAP data types can be used in web services (enterpirse services). But as @Carsten said, do not, expose SAP tables as is with it's ugly names. Help conusmer and provide meaningfull field names :)
