Connect SAP Offline Help with TREX

Hello all,

short question:

Does anybody have a short how-to guide with connecting a TREX Engine (I have 7.0) with the installed SAP Offline Help (HTML).

Well, I know how to connect it but I want to use the integrated search form in the top right inspite of using the TREX Search of help.sap.com

In that way our users stay within the LAN without causing any Firewall traffic

Thanks,

Philipp
