Question
Need to calculate number of business days, excluding weekends and holidays
I am writing an On-Time Shipments report and have to determine how many business days have lapsed between the requested-date and the shipped-date, minus weekends and holidays.
I have a holiday table with all holidays entered for the next several years. Therefore, I can't use a piece of code that hardcodes the holidays in it (like this one: http://www.kenhamady.com/f
Does anybody have a formula I can use? The link that has answered this frequent question on EE is broken so that's no help (http://support.businessob
Thanks much,

Basic idea of the formula. James was thinking along the same basic lines.
In the main report
Right click the report header left margin
Click INSERT SECTION BELOW
Repeat
You should now have
RHa, RHb, RHc
In RHa
WhilePrintingRecords;
Shared DateVar Array Holidays;
""
In RHb add the subreport
In the subreport details add a formula
WhilePrintingRecords;
Shared DateVar Array Holidays;
Local NumberVar CurrentSize;
CurrentSize := UBound(Holidays);
ReDim Preserve Holidays[CurrentSize+1];
Holidays[CurrentSize+1] := {DateField};
""
Use RHc for the main report report header
mlmcc
Yep, he's right. That's the basic idea. When the subreport finishes, the Holidays array should have all of the dates from your holiday table in it, and since it's a shared variable, you can use it in formulas in the main report. The only remaining detail is that you have to make sure that you also declare the Holidays array as Shared in your formula to calculate the business days, meaning that you'll have to change the declaration in the formula on Ken Hamady's site. Otherwise, CR will create a new Holidays array (separate from the one in the subreport) and you won't get the dates from your table.
James
I was wondering why you asked if this was for the main report. I thought you might be thinking of using a subreport too, but I didn't see why it mattered if you were going to calculate the days in the main report or a subreport. I get it now. For my idea it wouldn't matter, but for yours it would.

To count weekdays only, use the following formula:
DateDiff ("d", {due_date}, {despatch_date}) -
DateDiff ("ww", {due_date}, {despatch_date}, crSaturday) -
DateDiff ("ww", {due_date}, {despatch_date}, crSunday)
I'll thik about the holidays....
