Incorrect difference in time between 2 values of same column

RRaj_293 — Fri, 06 Sep 2024 03:55:11 GMT

Hello,

I'm trying to find the difference in time(single column-META_CREATE_DATE) between the two process status - 'New Email' which is the start of the process and 'Complete' which is the end of the process for each 'GUID'.

These are the measures I have created to calculate the 'processing time'.

New Email Time =

VAR newemailtime = MIN('Tbl1'[META_CREATE_DATE])

RETURN

CALCULATE(newemailtime,FILTER('Tbl1','Tbl1'[PROCESS_STATUS] = "NEW EMAIL"))

Complete Status Time =

VAR completetime = MAX('Tbl1'[META_CREATE_DATE])

RETURN

CALCULATE(completetime, FILTER('Tbl1','Tbl1'[PROCESS_STATUS] = "COMPLETE"))

Processing Time = CONCATENATE(MINUTE([Complete Status Time]-[New Email Time]) & " Min " , SECOND([Complete Status Time]-[New Email Time])& " Sec")

The Issue is for some of the GUIDs both 'New Email Time' and 'Complete Status Time' is picking up the same datetime value which is of 'New Email' status. Ex- for GUID highlighted for both status calculations same value is being picked hence showing 0Min0Sec

How do I fix this? I'm not sure what's wrong with my DAX!

Any advice appreciated.

Hi RRaj_293 - can you check that you are picking up the earliest (MIN) timestamp for the 'New Email' process status and using the GUID to isolate the calculation for each unique row.

New Email Time =
CALCULATE(
MIN('Tbl1'[META_CREATE_DATE]),
FILTER('Tbl1', 'Tbl1'[PROCESS_STATUS] = "NEW EMAIL" && 'Tbl1'[GUID] = EARLIER('Tbl1'[GUID]))
)

similarly for latest (MAX) timestamp for the 'Complete' process status while using the same GUID filtering Complete Status Time =
CALCULATE(
MAX('Tbl1'[META_CREATE_DATE]),
FILTER('Tbl1', 'Tbl1'[PROCESS_STATUS] = "COMPLETE" && 'Tbl1'[GUID] = EARLIER('Tbl1'[GUID]))
)

Now use datediff function

Processing Time =
VAR StartTime = [New Email Time]
VAR EndTime = [Complete Status Time]
RETURN
IF(
ISBLANK(StartTime) || ISBLANK(EndTime),
"No Data",
FORMAT(
DATEDIFF(StartTime, EndTime, SECOND) / 60, "0") & " Min " &
MOD(DATEDIFF(StartTime, EndTime, SECOND), 60) & " Sec"
)

The processing time should now correctly calculate the difference between the 'New Email' and 'Complete' process statuses

Hope this helps.

RRaj_293 Try with:

New Email Time =
CALCULATE(
MIN('Tbl1'[META_CREATE_DATE]),
FILTER('Tbl1', 'Tbl1'[PROCESS_STATUS] = "NEW EMAIL")
)

Complete Status Time =
CALCULATE(
MAX('Tbl1'[META_CREATE_DATE]),
FILTER('Tbl1', 'Tbl1'[PROCESS_STATUS] = "COMPLETE")
)

Processing Time =
IF(
[Complete Status Time] <> [New Email Time],
CONCATENATE(
MINUTE([Complete Status Time] - [New Email Time]) & " Min ",
SECOND([Complete Status Time] - [New Email Time]) & " Sec"
),
"0 Min 0 Sec"
)

Thank you rajendraongole1 and BeaBF . I created something in similar lines and its now working as expected!

Here;s my working DAX -

New Email Time =

VAR newemailtime = MIN('Tbl1'[META_CREATE_DATE])

RETURN

CALCULATE(newemailtime,FILTER('Tbl1','Tbl1'[PROC_STS] = "NEW EMAIL"))

Final =

IF(Min(Tbl1[PROC_SEQ])= 10 && Max(Tbl1[PROC_SEQ])=100 , CONCATENATE(MINUTE([Complete Status Time]-[New Email Time]) & " Min " , SECOND([Complete Status Time]-[New Email Time])& " Sec"), "Incomplete Process")

However , Moving on with that solution I need to find the average processing time for each customer (total processing time/distinct count GUID) and display the final average time in Hours:Min:Sec.

Here's is whats is done so far -

Fore each customer's GUID which goes through a process sequence from 10(Process status = New Email) and 100 (Process status = Complete) , I have managed to find the time difference in Min:Sec format and the ones which dont complete the cycle (i.e process status <> Complete as last step) its marked as "Incomplete process". Its calculation DAX is as below -

Test_ProcessTime = IF(Min(Tbl1[PROCESS_SEQUENCE])= 10 && Max(Tbl1[PROCESS_SEQUENCE])=100 , CONCATENATE(MINUTE([Complete Status Time]-[New Email Time]) & " Min " , SECOND([Complete Status Time]-[New Email Time])& " Sec"), "Incomplete Process")

I should now find the average time for each customer ignoring the "Incomplete process" ones. So I converted the time in Seconds and "Incomplete process" is made 0 for ease of calculation in the measure "Test_Totlprocessing TimeinSec" .

Test_Totlprocessing TimeinSec = IF(Min(Tbl1[PROCESS_SEQUENCE])= 10 && Max(Tbl1[PROCESS_SEQUENCE])=100 , MINUTE([Complete Status Time]-[New Email Time])*60 + SECOND([Complete Status Time]-[New Email Time]),0)

Test_Avgprocessing Time =

VAR cnt = DISTINCTCOUNT('Tbl1'[GUID])

RETURN

SUM(Test_Totlprocessing TimeinSec)/cnt ?

Question - The average calculation is not working right. The seconds are not summing up correctly for each customer- Numerator SUM(Test_Totlprocessing TimeinSec) is giving incorrect result. Counts of distinct GUID (denominator) is correct but the sum of total processing time in seconds is not correct and hence average goes wrong. I'm not sure why its incorrect. For customers which have 'Incomplete process' the sum shows as 0.

Please help! How do I find the correct average and display it in HH:MM:SS format?

CustomerName	GUID	Test_ProcessTime	Test_Totlprocessing TimeinSec
ABC	00272fd1	4 Min 58 Sec	298
ABC	02a8b18b	17 Min 59 Sec	1079
ABC	035b8aa0	Incomplete Process	0
ABC	075ddfa8	Incomplete Process	0
ABC	0bba233d	2 Min 33 Sec	153
XYZ	1307af71	3 Min 24 Sec	204
XYZ	148fd7bd	2 Min 8 Sec	128
XYZ	1655b305	5 Min 18 Sec	318
XYZ	1be32838	54 Min 13 Sec	3253
XYZ	1c3ab04e	5 Min 11 Sec	311

Thank you rajendraongole1 and BeaBF . I think it would be better if I give the whole requirement.

Basically , In the sample data below - I want find the average time taken for prrocessing at a customer level. A process is said to be complete only when it starts with a 'New Email' , Process seq = 10 and ends with 'Complete' Status -Process seq = 100. If anything else its an incomplete process and can be considered as 0(processing time) for ease of calculation.

In the below sample data - Expected output - for Customer 'WX V5' , ID = '00d8d10c%' time taken for processing =

2024-08-13 13:03:13 (createdatetime where process status = complete) - 2024-08-13 13:01:38 (createdatetime where process status = New Email) = 0:02:20 (hh:mm:ss) . Similarly for each ID for each customer we need to calculate the time taken for each successfull cycle and then find the average time for each customer. One customer could process multiple IDs. Hence ID is the lowest grain.

Please advice . Hope the sample data helps give better clarity.
