Converting Dates to time format for duration and applying a rate structure

What I am working on next is to change the extracted value (string,date) to time format - change the last transaction record to time format, subtract from each other and convert to minutes.

This will be Duration and then apply a rate structure (1day=$14,00 : 30 mins intervals =$1 with a max of $14/day) to the duration for the Theoretical Revenue.

Please see the attatched .rpt file for further details.  report imageGalthousePARC.rpt

What dates/times are being compared?

Is it the creation to last transaction?

Yes that is correct, creation pulled with our previous picture statement and last transaction from the grouped data.

The dates in the sample seem a long way apart.  Is this just test data?

My system is interpreting the dates as May rather than March

Take a look at the  report

'My system is interpreting the dates as May rather than March'  (mlmcc)

Me too and I'm in a different region.  It looks like the raw data may be different to what you are expecting..

A date is a date is a date..
A datetime field which is correctly input in one region is correct for every region.
Problems arise if at some stage someone has used a formatting expression in some code or sql  to present the date in a particular way.  That converts the value from a date/datetime  datatype to a string it may no longer be interepreted correctly out of its own region.

Your report regards the Last Transaction as a genuine datetime field - which means in the database it is a datetime field and holds the values you are seeing in the report- which are MAY values not March.

If you think that these dates should be March then I would say that you need to know why they have been stored incorrectly in the database.  If you don't know why, and in particular you don't know whether the 'error' will persist for all data then any corrective action you take for this sample might not apply to the next one.

The month and day values can be swapped using a Dateserial() function to produce March dates, but as I say this process might not be applicable to all your data unless you can somehow verify that the problem  occurs with every date.

Sorry guys, the raw data just needs to be adjusted and MM DD needs to be swapped around when pulling it.

The original data was exported DD mm .

You cannot modify the raw data using  CR.

You can create a formula to get a converted date within CR..

Dateserial(Year({table.datefield}), Day({table.datefield}), Month({table.datefield}) + Timevalue({table.datefield})

Did you look at the formulas for calculating the duration and revenue.  They will remain the same once you get the data pull so it reflects the dates correctly.

I did see that, thank you very much - all seems as I was anticipating.

Final Question, anyone familiar with crystalexperts.com - Is it worth paying another yearly fee or do you thing expertsexchange on it's own will suffice as a resource while I'm learning and getting familiar with the fine angles of Crystal reporting ?.....
Thoughts....

crystalexperts.com is actually an offshoot of EE.  It is specifically for Crystal questions.  The "experts" participating are also very limited.  You will not get any better help there than here and also the resource is not as good for finding information.

The intent of the "microsites" like CrystalExperts.com is to get participation from users looking for subject specific help and information.
