So I need two date formulas:

1. Calculate the third to last business day of the month (last business day - 2) of the PRIOR month.
2. Calculate the third to last business day of the month (last business day - 2) of the CURRENT month.

but does that handle just business days? or just any calendar day? Needs to calculate based on business days only.

Is "business days" just Mon - Fri, or something else?  Are holidays a factor?

 Since you didn't specify, I'm guessing that it's just Mon - Fri, but I thought I'd check.

DO you have the last day of the month available or do you need to calculate that?

Here is the basic formula for 3rd workday

WhilePrintingRecords;
If DayofWeek({Sheet2_.End Of Month}) in [1,2,3] then
    {Sheet2_.End Of Month} - 4
Else if DayofWeek({Sheet2_.End Of Month}) = 7 then
    {Sheet2_.End Of Month} - 3
Else
    {Sheet2_.End Of Month} - 2

Updated to calculate last day of month based on current date

Name - Last Day Of Current Month
WhilePrintingRecords;
Local DateVar LastDay;
LastDay := DateSerial(Year(CurrentDate), Month(CurrentDate) + 1, 0);
If DayofWeek(LastDay ) in [1,2,3] then
   LastDay  - 4
Else if DayofWeek(LastDay ) = 7 then
    LastDay - 3
Else
    LastDay  - 2

Open in new window


Name - Last Day Of PreviousMonth
WhilePrintingRecords;
Local DateVar LastDay;
LastDay := DateSerial(Year(CurrentDate), Month(CurrentDate), 0);
If DayofWeek(LastDay ) in [1,2,3] then
    LastDay  - 4
Else if DayofWeek(LastDay ) = 7 then
    LastDay  - 3
Else
   LastDay  - 2

mlmcc:

So I am trying to reference this field in another formula field and I get the following error...will it not be possible to reference the result of this formula field? Ultimately, I need to reference this field to conditionally sum a different field.
