We have an existing customer Enterprise Web Service that was generated from a function group. The web service originally had four operations based on four function modules: #1, #2, #3 and #4.
In the Service Definition Editor in SAPgui, I added operation #5 to the service by right-clicking the service name in the Internal View and External View tabs and choosing Add Operation in each tab. This successfully added operation #5 to the service definition. I can see its artifacts in the updated WSDL.

Testing the new operation in SoapUI however, we get an error. According to SRT_ELOG, it's a binding error. I notice in SoapUI that the new operation has no action assigned.

And when I open the service in SOAMANAGER, I see the operation #5 is not present. Only operations #1, #2, #3 and #4 are present. There is no way that I see to add the missing operation.

I tried deactivating the reactivating the service in both SOAMANAGER and in SICF, but the missing operation #5 didn't appear. I've googled SAP.com for a solution but haven't found it. Looking for suggestions.
Cheers,
Amy King
