Hi,

If you are on NW2004s, you can use the suspend and resume plugs, see here:

Tony,

Also I haven't checked this functionality myself yet (very old NW04s SP , the documentation AFAIK does not enforce any SAP-specific libraries to be used to resume application, here is a cite:

<b>The External Application</b>

The external application received the URL, which it must use later to call the Web Dynpro application again, in the form of a parameter. This parameter is called sap-wd-resumeurl and consists of the URL of the Web Dynpro application and of a parameter containing the session ID.

====

Any J2EE (and non-J2EE) application may resume WD application. The only thing you need is URL with 2 parameters. It is passed as part of "suspend" -- your (external) application is invoked with this additional parameter (cite again):

<b>Suspend Plug</b>

When the suspend plug is fired, the parameter Url is passed to which you have assigned the URL of the target application. The URL which is required to resume the Web Dynpro application from within the external application is automatically determined by the Web Dynpro runtime and attached as a URL parameter to the URL of the target application passed.

====

So there are should be no problems and no portal API dependencies.
