Update Lunch column break according to schedule start/end time.

Please attach a sample workbook.

Hi Martin,
Everything is included in the other thread, the sample workbook along with the current logic used for calculating times, we're just missing one column which is the lunch break.
Thanks,
Ben

Please re-attach the sample workbook from that thread because I don't see it.

Attached.

Thanks,
Ben

Hi,

Mostly are fine.
However some numbers are negative, see below.

StartTime      EndTime      Lunch      TotalHours      
9:00 AM      6:30 PM      -0.5      9.5       
7:00 AM      7:30 PM      -0.5      12.5       
7:15 AM      12:15 AM      -21      14       
8:00 AM      12:00 AM      -22      14       
8:00 AM      3:15 PM      -0.25      7.25       
8:00 AM      3:30 PM      -0.5      7.5       
8:00 AM      4:15 PM      -0.25      8.25       
7:00 AM      11:45 AM      -0.75      4.75

Hi Bill,
Not in the office.
Will do it on Monday.
Have a nice weekend.
Thanks,
Ben

Hi Bill,

We are still getting negative values for lunch (3rd column), see below.

7:15 AM      12:15 AM      -21      14
8:00 AM      12:00 AM      -22      14
7:30 AM      12:00 AM      -23      15.5

Thanks,
Ben

In addition, the following records didn't get lunch, neither did they got AM/PM...

3:00      11:30            7.5
11:30      7:30            6

Thanks,
Ben

Okay, I'll have to revisit the logic I'm using and shake out the issues...

---

»bp

So can we clarify something?  Will the input start and end times in the file being read have AM and PM already on all values?  Or will there be no AM and PM on any values?  Or is there a mix?

The way you have the data structured with a start date but no end date makes this a challenging question, and some assumptions have to be made.  I want to make sure I know what the incoming data will always look like so I make the right assumptions.

Hi,

Will the input start and end times in the file being read have AM and PM already on all values?  Or will there be no AM and PM on any values?  Or is there a mix?

There will be a mix as original data comes from from two sources, one with AM/PM and one w/o them.

The way you have the data structured with a start date but no end date

Are you referring to Start/End times? In cases where there is no start or end time I guess you can ignore them and no need to do anything.

...makes this a challenging question

If that turns out to be quite challenging perhaps would close the question and open another one on the remaining issues so you can be awarded properly.

if you want to try it there...

I can test for errors or just randomly but real testing would have to wait for users tom.

Thanks,
Ben

while testing this new version I came across these records.

7:00 PM      12:00      -12      5      

which should be filled with 12AM and no lunch.

and
 11:45      8:00      -10      6.25
which should be either AM or PM, and lunch 2 hours.

P.S. I might be wrong, so perhaps lets wait for users to say their input.

Thanks,
Ben

When I ran these two test case through the latest version I sent you:

,a,b,2/1/2019,7:00 PM,12:00,,5,,,
,a,b,2/1/2019,11:45,8:00,,6.25,,,

Select allOpen in new window

I got the correct output I believe of:

,a,b,2/1/2019,7:00:00 PM,12:00:00 AM,0,5,,,
,a,b,2/1/2019,11:45:00 AM,8:00:00 PM,2,6.25,,,

Would prefer to add something to this script.
Are you avail for a new Q?

Thanks,
