How to Create an Adapter Handler
You can create a send or receive adapter handler by using the BizTalk Server Administration Console.
You must be a member of the Single Sign-On Administrators group to create an adapter handler.
To create an adapter handler
In the BizTalk Server Administration Console, expand BizTalk Server Administration, expand BizTalk Group, expand Platform Settings, and then expand Adapters.
In the expanded adapter list, right-click the adapter for which you would like to add a send or receive handler, point to New, and then click Send Handler to create a send handler or click Receive Handler to create a receive handler.
In the <host name> Properties dialog box, on the General tab, in the Host Name list, select the host with which the adapter handler will be associated.
If you are creating an adapter send handler, select the option to Make this the default handler if you would like for this to be the default send handler for this adapter.
