DATEDIFF between Rows

HI, Magomed

After my test, you could do these follow my steps as below:

Step1:

Add a group rank column 

group rank = RANKX(FILTER(Table1,Table1[Trackingtocken]=EARLIER(Table1[Trackingtocken])),Table1[createdon],,ASC)

Step2:

Use EARLIER Function add a datediff column

Datediff = DATEDIFF(CALCULATE(MAX(Table1[createdon]),FILTER(Table1,Table1[Trackingtocken]=EARLIER(Table1[Trackingtocken])&&Table1[group rank]=EARLIER(Table1[group rank])-1)),Table1[createdon],MINUTE)

Result:

here is pbix, please try it.
