When a My webMethods user issues a request that requires access to Trading Networks data, My webMethods Server executes a Trading Networks service on the Integration Server to perform the requested action, and then displays the results in My webMethods. To execute the service, My webMethods Server uses the credentials of the logged-in My webMethods user. The My webMethods user must therefore have authority in Integration Server to execute the service.

In Integration Server, Trading Networks services are protected by the TNMWSUsers ACL. For My webMethods users to execute the services, the My webMethods TN MWS Users role must be in the Allowed list of the TNMWSUsers ACL, and is by default. However, you must still grant the user's role the appropriate general functional permissions and data permissions. For instructions, see Granting Users General Functional Permissions and Granting Users Data Permissions.
