Loop-like feature in Power BI?

Dear all

 

I am trying to return different value in a new column if I find a specific value in several rows.

 

For example, I am trying to return the earliest view date when I found "Contact Customer Service" for each case and return, and if there is no any "Contact Customer Service" for a case, return the last view date.

 

Is it possible to have this loop funtion in Power BI? 

 

CaseTime_StampActionFirst or Last View
X0012/1/2021View2/1/2021
X0012/3/2021View2/1/2021
X0012/18/2021Place into Cart2/1/2021
X0012/19/2021Contact Customer Service2/1/2021
X0012/22/2021Cancel2/1/2021
X0021/3/2021View1/3/2021
X0021/19/2021Place into Cart1/3/2021
X0022/3/2021Purchase1/3/2021
X0022/7/2021Paid1/3/2021
X0033/2/2021View3/6/2021
X0033/4/2021View3/6/2021

X0033/6/2021View3/6/2021
X0033/11/2021Paid3/6/2021

 

Thank you in advance!

      Thanks for your answer! Yet, there is an error "A circulated dependency was detected..." now.  

       

      In your file, this error is not found, but the result seems different. 😞

       

       

      Could you kindly take another look? Much appreciated!
