Problem when adding ABAP custom webservice with Visual Studio 2010

[Former Member]

Hi All,

After creating a webservice for a custom RFC function developed in a ECC6.0 SAP machine, I tried to add it to a Visual Studio 2010 windows aplication (through a web reference connection).

The sequence I've done is:

- Create RFC in ABAP, with testing ok

- Create a WEBSERVICE with the ABAP editor

- Configured the webservice with SICF with:

Procedure: Standard

Logon data: standard R3 user

Security requirement: Standard

Authentication: Standard SAP User

Then, in SOAMANAGER I copied the webservice URL and tried to add it to Visual Studio 2010, but it keeps asking me the user and password. I try to supply the R3 username and password but if fails.

Why is ECC6.0 asking the user and passord if I've defined a SAP user for the login process?

Is there any way to disable this?

Thanks,

Hello Manuel,

You can use the following code:

CredentialCache cache = new CredentialCache();
      cache.Add(new Uri("WEBSERVICEURL:PORTNUMBER/"), "Basic", new NetworkCredential("USERNAME", "PASSWORD"));

SAP needs a password.

Kind regards,

Thanks John,

The problem occurs when I try to add the webservice in Visual Studio 2010 to my project.

The system always asks for a user login and no matter what user I provide (R3 user, etc) the login always fails, thus not allowing me to add the webservice to my project.

Manuel,

Try the following system user with the next roles and profile:

Role

SAP_XI_APPL_SERV_USER

SAP_XI_RWB_SERV_USER

Profile

SAP_ALL, SAP_NEW

And login in with this systemuser.

Kind regards,

Hi,

Instead of a "Web Reference" service, I've change to a "Service Reference" in VS2010.

The I used the credentials snipt to add the user and password, and it worked ok.

Thanks anyway,
