Calling a WAD Report via BI_COMMAND

Hi experts!

Let me explain my scenario, I've an iView and a WAD Report. I create a button in the iView which is calling the WAD report

via hyperlink, sending a parameter which is needed by the WAD Report, with a formula using BI_COMMAND's:

http://URL?TEMPLATE=WA_NAV_PROY&BI_COMMAND_1-BI_COMMAND_TYPE=SET_VARIABLES_STATE&BI_COMMAND_1-VARIABLE_VALUES-VARIABLE_VALUE_1-VARIABLE_TYPE=VARIABLE_INPUT_STRING&BI_COMMAND_1-VARIABLE_VALUES-VARIABLE_VALUE_1-VARIABLE_TYPE-VARIABLE_INPUT_STRING=###001&BI_COMMAND_1-VARIABLE_VALUES-VARIABLE_VALUE_1-VARIABLE=VAR_PROY

That works ok!, when we push the button we get the information we want on a new page. But now we want to do something better.

Our WAD Report has a button which export the data on screen to a PDF. Anybody knows if it's possible to launch that

WAD Report from our iView, as we are doing, and get the PDF export without getting the information on screen?.

I found a How to Guide, which explain to do that, but it doesn't work for an entire model, it only works for the data we get

on a BAPI, Can anybody help me?.

Thank you!!.

Emilio.
