material discontinuation in MRP 4 tab

Hello gurus,

I am trying to run a cycle to discontinue a material with MRP activated with a new material. I have given the discontinuation indicTOR and date as well as a follow on material number. But still after the discontinuation date when I run the MRP instead of getting the follow on material I am getting the old material.

Please help if any other settings need to be maintained or any modifications need to be done in the procedure.
