Thanks for the reply karthik.
I'm aware of few BPC concepts. i came across chain failure where i don't have EPM access , so i tried to find out root cause but i couldn't find it in BI environment, later i heard about this t code, which helps in finding route cause for BPC issues in BI environment.
I tried to explore it, but i couldn't find informative. can you give some inputs on the this tcode.
Thanks for the help and appreciated.
