[Cognos91]

We can pass the product line code/ id as a static hyperlink to a third party site.

Question:  I am trying to mimic drill-through functionality from a chart but via a hyperlink that should direct to a third-part site but, passing the same parameters.
Is this even possible?

Possible solution ;
Create fake/ dummy drill-through reports. The drill-through links are created in the parent report. Now, using SDK could we read the code that is passing the parameters and direct the link to the third part site with the filtered parameters.
This may not require Hyperlink use then.
But what if we create a hyperlink on the data item used in the chart passing the same parameters to the third part site?
Any ideas...
