Today while I was trying to create a webservice for SAP function module , I have faced with a problem. The problem was that in SOAMANAGER i tried to create service endpoint and binding for my function module. But I couldnt find ‘None (HTTP)’ button under the following menu.
Provider Security Tab -> Transport Guarantee -> Communication Security
Then searching google i have found that it is because of the Transport Security configurations that i have done while creating Service Definition from my function module.
In order to correct the error , in SE80 I navigated to the right relevant package and then find the related Service Definition under Enterprise Services. Then i set Configuration->Security Profile->Transport Security->Profile to ‘None’.
