TM1 Forum

I was lookin into the Drill process of TM1. What's the difference with both since I see drill process as like TI while Drill Assignment are like creating rules.

Are drill process dynamic base on the cell you drill through from the orginating cell?

What guide give a better detail of the drill through process cause I think there is a little detail on the developer's guide but not much detail on the flexibility of its function.

Drill Process(es) are the TIs which return the data you have drilled to (cube or relational).
Drill Assignment controls which drill processes are available where in the cube.
As an example, if you have budget and actual data in your cube and want to drill back to the ledger for the actuals, the drill assignment would look a bit like:

['Actual'] = s:'ToLedger';
