How to use SOAP Action ?

Hi All,

In SAP PI, i need to use the SOAP action in the receiver communication channel..

From the webservice, i need to use the method: getEncryptedHexDataFromString

SOAP action given in the webservice is as below:

<soap:operation soapAction="getEncryptedHexDataFromStringAction"/>

This SOAP action does not have URL.. it has only method name.. Whether this is sufficient or URL is needed...Please suggest on this..

Thanks,'
