How to group dates by week and Month in Crystal where the week with most days in a particular month get grouped in that month.

Basically what I'm trying to do is correct the grouping so that the weekly groups are falling into the correct group month.. In other words, if mon-wed falls in the end of January and thur and fri are in February, I want that week to be grouped with January. If only Mon and Tues falls in January and Wed-Fri are February then the week should be grouped with February.

I believe the problem may lie with my formulas as I'm trying to group the weeks by the week ending day of Saturday..

Here is what my formulas are now.

DateGrouping:
{BAQReportResult.LaborDtl.PayrollDate} +
(7 - DayofWeek({BAQReportResult.LaborDtl.PayrollDate},crSunday))

DateGrouping2:
{@DateGrouping} - (DayofWeek({@DateGrouping}, crSaturday)-1)

In group expert the groups are
1. DateGrouping (by Year)
2. DateGrouping (by Month)
3. DateGrouping (by Day, displays as week)

Thanks for the help! Let me know if you need any additional information

Will there be a record for every day of the week ?

No necessarily.. Some times the shop will shut down and no transactions will take place during that time.. and usually Sundays there will not be any records.

Ok try this

//@MonthNumber
WhileReadingRecords;
NumberVar MonthNo := Month({@DateGrouping});
Numbervar WkDay := DayofWeek({@DateGrouping}, crMonday);

If WkDay < 3 Then
    If MonthNo <> Month({display_booking.date_created} + (3 - Wkday)) Then
        MonthNo := MonthNo + 1
Else If WkDay > 3 Then
    If MonthNo <> Month({display_booking.date_created} + (Wkday -3)) Then
        MonthNo := MonthNo - 1
    Else
        Month({display_booking.date_created});

MonthNo

Open in new window

Create a group on this formula in between Year and Week on the group options tab select use formula as group name and enter the formula

MonthName({@MonthNumber})

Hmm.. Didn't seem to change anything.. For instance, week ending 4/2/2011 is still being grouped with April.. I'm pretty sure I got your formula set up correctly..

My updated groups right now are
1. DateGrouping (by Year)
2. MonthNumber (by Month) (added Monthname({@MonthNumber}) formula to Group Name formula)
3. DateGrouping (by Day, displays as week)

GJParker

Ok so your week group is week ending and not week commencing in that case you will need to change the week formula

({display_booking.date_created} - (DayOfWeek ({display_booking.date_created},crSunday)) + 7)

Open in new window

and then change the monthnumber formula

WhileReadingRecords;
NumberVar MonthNo := Month({@DateGrouping});
Numbervar WkDay := DayofWeek({@DateGrouping}, crMonday);

If WkDay < 3 Then
    If MonthNo <> Month({@DateGrouping} + (3 - Wkday)) Then
        MonthNo := MonthNo + 1
    Else
        MonthNo
Else If WkDay > 3 Then
    If MonthNo <> Month({@DateGrouping} - (Wkday -3)) Then
        MonthNo := MonthNo - 1
    Else
        MonthNo
Else
        MonthNo;

MonthNo

Open in new window

Well that made a change for sure, still not quite right though..
Currently it looks like this:

GJParker

That's not the result I get when I use the formulas provided. Can you upload your report with saved data and I will have a look at how you have set it up.

Jeremy Campbell

ASKER

That would be easy but it contains a lot of sensitive data.. Is there a way for me to summarize the setup perhaps?

Jeremy Campbell

Groups are setup as follows:

First Group (Year) looks like this:

Second Group (Month) Looks like this:

In the options the use a formula as Group Name is as follows:

MonthName({@MonthNumber})

The MonthNumber formula is:
WhileReadingRecords;
NumberVar MonthNo := Month({@DateGrouping});
Numbervar WkDay := DayofWeek({@DateGrouping}, crMonday);

If WkDay < 3 Then
If MonthNo <> Month({@DateGrouping} + (3 - Wkday)) Then
MonthNo := MonthNo + 1
Else
MonthNo
Else If WkDay > 3 Then
If MonthNo <> Month({@DateGrouping} - (Wkday -3)) Then
MonthNo := MonthNo - 1
Else
MonthNo
Else
MonthNo;

MonthNo

The DateGrouping Formula is:
{BAQReportResult.LaborDtl.PayrollDate} +
(7 - DayofWeek({BAQReportResult.LaborDtl.PayrollDate},crSunday))

The DateGrouping2 Formula is:
{@DateGrouping} - (DayofWeek({@DateGrouping}, crSunday)+7)

The last group is setup as so:

Here's the test report and data I have setup
date-range-test.rpt
Dates.xls

Ah, I was able to replicate what you did with your test file.. Sorry, I didn't think about creating an excel file and using that as a source for a test file..

I noticed one issue though.. And this is happening on my report exactly how it happens on your test report.

Have a look at week ending 6/4/2011.. For some reason Tuesday May 31st is getting pulled into week ending 6/4 under the month of May.. (see the attached picture) I'm totally baffled by this. Only thing I can think of is it has something to do with it being the 31st..

Any ideas?
