How to access to the BAPI input parameter in c#

Hi,

I'm developing an application in C# using SUP SAP data source. I have a problem to access to the input parameter in my BAPI in the C# source code (Microsoft Visual Studio).

I could see input + output + tables of my BAPI in the SUP workspace but i couldn't find input parameters in the generated C# source code.

Have you any idea to resolve this issue ?

An example of C# source code to fill the BAPI input parameter in the application ?

I thank you in advance,
