IBM Cognos TM1 Rules & Feeders
TM1 Rules & Feeders are concepts related to the IBM Cognos TM1 solution. TM1 feeders feed every cell that is calculated by a rule. Feeders are not used to feed rules that apply to consolidated cells. Feeders are not required to make rules work, however they can improve performance in sparse cubes.
Rules and feeders are written in the Rules Editor. The feeder statements are starting with declaring ‘FEEDERS' before starting the rule. Rules are calculations done in a cube and can work across dimensions, point to data in other cubes and access metadata.
