Kaspar Christensen a consultant from Denmark published an cool paper on JScript that I swiped some of for TechEd in a session that Jeff Louckes and I did. With very little work, you are able to move data from a HTML Page or ASPX page in an iFrame to the main CRM form. This allows for some interesting data integration scenarios.
The one outlined at TechEd was of an internal credit application that assigned a score based upon a number of different items in other internal systems. It then posted a credit score to each account. That data needs to be imported into the CRM system, but doin a traditional data import would be difficult and time consuming. :-)
So we render the credit score for each account in an iFrame in CRM and have the value from the HTML Page put back on the CRM form.
Here is the orginal form before anything is clicked.
Here it is after clicking on the Save Credit Score and Appove Credit Buttons.
This was of course all was inspired by this commerical I hate that is blasted all over the TV...
