[swapan1189]

Hi, Can someone share the way to automate the clearing cache part by creating a trigger.

The below blog describes how to create trigger for a report. If anybody can explain the same for clearing cache.

My clients are having some data issues with the Cognos Reports after every ETL load. So, they end up requesting us to clear cache and we have to do this multiples times in a month. So, please suggest way to automate the clearing cache using a trigger file in the cognos server.
