Error starting the SOAMANAGER for Configuration

Hi fellows,

I've created a web service from a RFC. When I tried to start the SOAMANAGER for configuration to create the an endpoint I've got the error bellow:

"Invalid index 1 when setting lead selection; context node: MAIN.1.NODE_SEARCH_TABLE"

I tried to acess the SOAMANAGER transaction to find the service description created. I found it but when I tried to create the endpoint I got the errors:

"Error: Error when reading variant "ZWS_TESTE" of servicedefinition "ZWS_TESTE": An exception with the type CX_SY_REF_IS_INITIAL oc "

And

"No service/endpoint selected"

Someone knows what am I missing?
