Flagging DateTime records in Power Query with multiple conditions

[Mann]

Hi Guys,

I need to Flag some records with multiple conditions in Power Query. I am not finding the efficient way of doing it with minimal custom columns. Rules are:

1. Flag "0" a record when Start DateTime and End DateTime, time value is within groups of 5 min interval. (Example: Ind ID= 11,13,15,18,19,20). Groups of 5min are standard values like: 8:00:00 --> 8:05:00 --> 8:10:00 ..... -->8:55:00-->9:00:00
2. Flag "1" if records have start time and end time same and on the standard values like (Ind ID= 12)
3. Flag "1" if records have start time and end time across standard values like (Ind ID= 14,16,17)

Sample Data: (Flag column needs to be inserted in Power Query)

Ind ID	Status From Time	Status To Time	Flag
11	10/10/2019 8:02:00AM	10/10/2019 8:02:00AM	0
12	10/10/2019 8:05:00AM	10/10/2019 8:05:00AM	1
13	10/10/2019 8:02:00AM	10/10/2019 8:04:00AM	0
14	10/10/2019 8:02:00AM	10/10/2019 8:05:00AM	1
15	10/10/2019 8:05:02AM	10/10/2019 8:05:02AM	0
16	10/10/2019 8:04:58AM	10/10/2019 8:05:02AM	1
17	10/10/2019 8:05:00AM	10/10/2019 8:05:02AM	1
18	10/10/2019 8:22:00AM	10/10/2019 8:22:00AM	0
19	10/10/2019 8:32:00AM	10/10/2019 8:34:00AM	0
20	10/10/2019 8:05:02AM	10/10/2019 8:08:12AM	0

Thanks

Interesting puzzle. I am going to look at this this weekend, so someone may answer first, but I do have a question. Your criteria has conflicts. Row 11 satisfies both #1 and #2 criteria.

Hi @edhans

Row 11 doesnt satisfy Criteria #2 as it is not a standard value. By standard value I mean values like multiple of 5min e.g. 8:00, 8:05, 8:10.. etc.
It only satisfy Criteria #1 that is when start value and end value (whether it is same or not) is within standard values, in this case Row 11 is between 8:00 and 8:05.

I hope it clarifies.

Hi @Mann ,

if DateTime.From(Number.RoundUp(Number.From([Status From Time])*288,0)/288) <> DateTime.From(Number.RoundUp(Number.From([Status To Time])*288,0)/288) then "1#3" else if Number.Mod(Time.Minute([Status From Time]),5)
 = 0 and Time.Second([Status From Time])= 0 and [Status From Time]= [Status To Time] then "1#2" else if Duration.Minutes([Status To Time]-[Status From Time])<=5 then 0 else "-"

I marked the ones as to the condition from your specs. Therefore 1#2 is 1 due to your number 2 requirement. As I said in my message to you I don't think 14,16,and 17 can be the same, as 8:05:00 has to be the beginning or the end of a segment. My logic says that it is at the beginning. end.

If beginning time minutes divided by 5 equals zero, and seconds are zero and if the two times match we solve #2 req.

If we roundup to the next five minutes, both times, and they are not the same, then we have crossed a boundary and #3 is solved.

Everything  else is zero unless the time duration > 5, then you get a "-" .

I added a row that starts at 8:00:00 for testing.

This may work for you. 
Let me know if you have any questions.

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.

Hi @Nathaniel_C 

Thanks for the reply on this. 

Flag of 14,16 and 17 has to be "1" only as per this rule:

"Flag "1" if records have start time and end time across standard values like (Ind ID= 14,16,17)"

Let me elaborate:

We need to show some chart at every 5 min interval (standard values like 8:00:00, 8:05:00, 8:10:00...) so when for any individual he is detected on these standard values he should be picked for calculation.

Therefore,

14 - when his end time detected on standard value

16- when he is detected at standard value between start time and end time

17- when his start time detected on standard value.

I hope this clarifies. 

I checked your code, it worked fine can we include record 14 also there?

Hi @Mann ,
Try this, 14 now receives a 1, as do 12, 16, and 17 (I added a test for 21 which works as well)

if DateTime.From(Number.RoundUp(Number.From([Status From Time])*288,0)/288) <> DateTime.From(Number.RoundUp(Number.From([Status To Time])*288,0)/288) then "1" 

else if Number.Mod(Time.Minute([Status From Time]),5)
 = 0 and Time.Second([Status From Time])= 0 and [Status From Time]= [Status To Time] then "1" 

else if Number.Mod(Time.Minute([Status From Time]),5)
 = 0 and Time.Second([Status From Time])= 0 or  Number.Mod(Time.Minute([Status To Time]),5)
 = 0 and Time.Second([Status To Time])= 0 then 1 

else if Duration.Minutes([Status To Time]-[Status From Time])<=5 then 0 
else "-"

Thanks @Nathaniel_C..
This single custom column could handle all the conditions. Works great🙂
