I have to admit we missed documenting a new piece of functionality in the 10.1.3.3 release that I also have to admit that I only found out about yesterday ... thats rapid development for you.
If you want to integrate BIP with another application I have documented how to call BIP via a URL but in 10.1.3.3 we added another switch. In prior releases you could call a report via the URL but the complete UI would render. With 10.1.3.3 the _xmode switch was added, this allows you to control what gets rendered via the url.
To use the switch just add it to the URL for example:
where X is the mode number. The modes are:
0 - the complete BIP UI
1 - BIP UI showing template and output format drop boxes, the View and Export button
2 - BIP UI showing all in mode 1 plus any parameters
Useful stuff ... enjoy!
