Max and Min date/times based on condition

[Rajesh1]

hello all,

I have the following table:

v.ID.	Loc	Date	Status
V1	P	01-Feb-2019 13:00:00	Slow
V1	P	01-Feb-2019 12:30:00	Slow
V1	P	01-Feb-2019 12:15:00	Slow
V1	P	31-Jan-2019 23:00:00	Slow
V1	R	31-Jan-2019 20:30:00	Slow
V1	R	31-Jan-2019 18:00:00	Slow
V1	R	30-Jan-2019 16:00:00	Slow
V1	R	30-Jan-2019 14:00:00	Slow
V1	R	30-Jan-2019 12:00:00	Slow
V1	R	30-Jan-2019 11:00:00	Normal
V1	R	30-Jan-2019 10:00:00	Normal
V1	R	30-Jan-2019 09:00:00	Normal
V1	R	30-Jan-2019 07:00:00	Normal
V1	R	30-Jan-2019 06:30:00	Slow
V1	R	30-Jan-2019 01:00:00	Slow
V1	R	29-Jan-2019 23:00:00	Slow
V1	R	29-Jan-2019 18:00:00	Slow
V1	R	29-Jan-2019 15:00:00	Slow

There will be more rows for different vehicle Ids (v. ID) but for I've limited it to one vehicle id.

The expected output is to identify the latest date/time and earliest date/time for vid+loc+status combination. Then, compute the difference in days for this combination. The expected output for the above should be as below:

v. ID.	Loc	Status	From Date	To date	Days
V1	P	Slow	31-Jan-2019 23:00:00	01-Feb-2019 13:00:00	0.583333
V1	R	Slow	30-Jan-2019 12:00:00	31-Jan-2019 20:30:00	1.354167
V1	R	Normal	30-Jan-2019 07:00:00	30-Jan-2019 11:00:00	0.166667
V1	R	Slow	29-Jan-2019 15:00:00	30-Jan-2019 06:30:00	0.645833

I attempted various options like transpose, summarizecolumns with filter etc. but failed miserably.  Please can someone assist on how I am to go about achieving this.

thanks in advance.

Hi @Rajesh1 

Is there a column to define differnt vehicle running record as below?

v.ID.	Loc	Date	Status	column
V1	P	2/1/2019 13:00	Slow	1
V1	P	2/1/2019 12:30	Slow	1
V1	P	2/1/2019 12:15	Slow	1
V1	P	1/31/2019 23:00	Slow	1
V1	R	1/31/2019 20:30	Slow	2
V1	R	1/31/2019 18:00	Slow	2
V1	R	1/30/2019 16:00	Slow	2
V1	R	1/30/2019 14:00	Slow	2
V1	R	1/30/2019 12:00	Slow	2
V1	R	1/30/2019 11:00	Normal	3
V1	R	1/30/2019 10:00	Normal	3
V1	R	1/30/2019 9:00	Normal	3
V1	R	1/30/2019 7:00	Normal	3
V1	R	1/30/2019 6:30	Slow	4
V1	R	1/30/2019 1:00	Slow	4
V1	R	1/29/2019 23:00	Slow	4
V1	R	1/29/2019 18:00	Slow	4
V1	R	1/29/2019 15:00	Slow	4

From your screenshot and provided information, it is hard to differ the row 1 and row4.

v. ID.	Loc	Status	From Date	To date	Days
V1	P	Slow	########	########	0.583333	1
V1	R	Slow	########	########	1.354167	2
V1	R	Normal	########	########	0.166667	3
V1	R	Slow	########	########	0.645833	4

hi @v-juanli-msft ,

Thanks for your reply.

I have been unable to work out a way to create such a column. 
Tried Current_Column_Value = EARLIER(Column Value) in a calculate + filter.  I am yet to find a way to get this 'key' column created. If I am able to create this column, I can then do a summarizecolumn and get the job done.

This is where I am stuck at.

Looking forward to some ideas to achieve this.

Thanks again,

Rajesh
