@Rajan244 , A new column

= [No] + Rankx(Filter(Table, [No] = earlier([No]) ), [lat],asc, dense) /10

Hi @amitchandak Thank you for your quick reply. Actually I forgot to mention, need to make unique based on Container_no, and events. 

Also, if its possible can you please add littlebit explaination about query, so I could change by my dataset. Thanks again.

Thanks @amitchandak 

Used:

!no = RANKX(His_data, COMBINEVALUES(",", His_data[Container_No],COMBINEVALUES("-",[From],[To])),, ASC, DENSE) + ([no]/10)
