How to add new process in Process Chain

Hi Guys,

I am working on a requirement where I need to extract some data from 0CCA_C11. This cube is getting filled every morning with the Process chain which has a process "Delete overlapping Request'. I need to add the new cube in this Process chain. The new cube should get filled everyday from 0CCA_C11. But in order to successfully run 'Delete overlapping requset ' I also have to delete the data from new cube. HOw and which Processes should I add in this existing PROCESS CHAIN.

Any suggestions please?

Here is a pic of PC.
