Web Service run time error

Hi experts,

Now we are using the custom create web service to import the data into the custom bo via third party application.

In this place, the web service cannot execute because of the following error.

The detailed error description may not be available in logon language:  Message "Create{}" not supported (interface: "............." binding key: "............")

This is why? Is there any problem in custom web service or third party application?

Best regards,

TokeKit.
