Hi @Arka Banerjee,

I recently had a similar requirement. The company does not want to re-open closed cases, but copy them and create a new one with the same information as the previous case. 

For this, I created a UI Action for the SD to just easily copy the closed case and open a new one. 
You could use the same script, but not create a UI Action, but a BR or CC and adjust the script to accommodate your requirements.
