Managing SKIPCHECK and Feeders in IBM Cognos TM1
When you first begin to use TM1, especially if you came from the EP world as I did, you can quickly become enamored with how well TM1 can handle large cubes with ease. You can create multiple hierarchies within a cube and within those hierarchies TM1’s sparse consolidation algorithm aggregates values at light speed. You can reach out to virtually any data source with a Turbo Integrator (TI) process and create a dimension, create and populate a cube with data, or a myriad of other tasks only limited by the developer’s imagination. The challenge comes when you need to write rules governing more complex calculations or movement of data between cubes. No intuitive D-Links or BiF’s here. Everything must be coded, and getting the calculations to work properly requires mastering the art of feeders.
