Default trip schema

Question

Hi All,
In the Portal interface for Travel Management, I would like to default the Schema for Expense Reports.
That is, I want a specific schema to show up in the dropdown so that in most cases users can just click 'Apply' without needing to select a schema.
I followed these instructions:
Select Trip Schema
However, once the URL parameter is implemented, the selection screen is skipped.  On the second screen, it's no longer possible to change the schema.
So, I would like to either:
- Default the schema but not apply it, or
- Make it possible to change the schema after it has been applied
Thanks for any ideas,
Scott

Hi Raynard,
Thanks for your response.  We came to the same conclusion (not possible in the standard system).
We added the functionality by making a change to the standard Java Web Dynpro.  For anyone else looking at the same problem, here is the code change:
In package esstratre~sap.com, find the GeneralDataView from component VcTreGeneralData.  Starting at Line 179, replace the standard code:
     boolean isTripSchemaSelected = (wdContext.nodeValid_Trip_Schemes().getLeadSelection() >= 0);
     modifyViewForTripSchema(wdThis, wdContext, view, isTripSchemaSelected);
With this new code:
     boolean isTripSchemaSelected = (wdContext.nodeValid_Trip_Schemes().getLeadSelection() >= 0);
     if (firstTime && !isTripSchemaSelected) {
          wdContext.currentRFCInputParametersElement().setI_Trip_Schema("01");
     modifyViewForTripSchema(wdThis, wdContext, view, isTripSchemaSelected);
This change causes the selection of schema 01 when creating a new trip, but still allows the user to select a different schema before pressing Apply.
