    DATE formula nested in SUMIFS not picking up last day of month

    Hi,

    Happy New Year

    On my attached attendance tracker there is a report sheet called 'All Employees' which is designed to display how many days someone has taken per month, based on a selection from the attendance parameters drop-down menu.
    The basic concept of this page works, e.g employees' names list correctly and i can select the appropriate attendance parameter and get a result.

    However the issue occurs when some has a "attendance date" that is either the last day of the month or includes the last day of a month. (leave tracker sheet is used to record any leave)
    this renders my expected result to return nothing and leaves the monthly count unaffected.

    on the leave tracker there is wto employees both called Adam opn the leaver tracker with examples of leave that have the issue.
    1 is for the last day 31/01/2018 and the other is 29/05/2018 to 01/06/2018

    on the all employee reports page i should see the following
    Adam B should have a count of 1 in the Jan cell
    Adam P should have a count of 3 for May and 1 for Jun

    Selecting different attendance parameters doesn't affect the outcome, which leads me to believe my SUMIFS formula needs changing from a DATE to an EOMONTH but i can't get my head round how it should look for some reason

    If anyone can help or shed some light it would be great

    Thanks
    Mark

    Try

    =IF(SUMIFS(tbl_Leave[Days],tbl_Leave[Name],$D12,tbl_Leave[Start Date],">="&DATE(Calendar_Year,1,1),tbl_Leave[End Date],"<="&DATE(Calendar_Year,1,31),tbl_Leave[Leave],$S$7)<>0,SUMIFS(tbl_Leave[Days],tbl_Leave[Name],$D12,tbl_Leave[Start Date],">="&DATE(Calendar_Year,1,1),tbl_Leave[End Date],"<="&DATE(Calendar_Year,1,31),tbl_Leave[Leave],$S$7),"-")

    Hi John,

    Ive made the correction you suggested and now i get holidays for a complete month to work so that great. Thank You

    Still having the issue when a holiday rolls over from one month to the next.
    So i am having to work around this by putting in 2 holiday lines in the leave tracker for example
    29/01/2018 to 31/01/2018 (3 days)
    01/02/2018 to 02/02/2018 (2 days)

    Using your current formula you could make it more "generic":

    =IF(SUMIFS(tbl_Leave[Days],tbl_Leave[Name],$D11,tbl_Leave[Start Date],">="&DATE(Calendar_Year,MONTH(S$9&0),1),tbl_Leave[End Date],"<="&EOMONTH(DATE(Calendar_Year,MONTH(S$9&0),1),0),tbl_Leave[Leave],$S$7)<>0,SUMIFS(tbl_Leave[Days],tbl_Leave[Name],$D11,tbl_Leave[Start Date],">="&DATE(Calendar_Year,MONTH(S$9&0),1),tbl_Leave[End Date],"<="&EOMONTH(DATE(Calendar_Year,MONTH(S$9&0),1),0),tbl_Leave[Leave],$S$7),"-")

    Just an FYI for performance improvement in hiding 0's..

    Doing this basically repeats the actual calculation twice when it's not 0.
    =IF(SUMIFS(blah blah)<>0,SUMIFS(blah blah),"-")
    Repeating the same calculation twice.

    Try this instead
    =IFERROR(1/(1/SUMIFS(blah blah)),"-")

    This way you only do the actual calculation once.

    Jonmo,

    Thats a sneaky little trick but seems to work pretty well.
    Could you explain a bit more on the idea behind it please?

    John,

    the Last forumla you posted still has the same result so i will instruct the HR department to split the holidays if they cross over multiple months.

    Thanks for all the help again

    It's really just very simple math.
    Take ANY number (the result of your sumifs)
    Divide 1 by that number.
    Then divide 1 by that result.
    This will return the same original number
    Unless the original number is 0 (or it's not a number at all)
    In that case, it returns an error, #Div/0 if the original number was 0, or #Value! if it was a non numeric value.
    Then it's handled by IFERROR.

    X = Any Number
    Z = 1 divided by X
    1 divided by Z = X
    Unless X is 0 or non numeric.

    Hope that helps.
