Three dates convert into month

Mon, 08 Feb 2016 13:48:57 GMT

Hi All,

I have a situation in which I have three dates; start date, end date, and cancel date. I have to combine these three dates and make them into one date called the desired date. Hopefully once I have this desired date I want to make a Month (desireddate) as desiredMonth so by clicking on a certain month; all the three dates will get filtered out in the back end for the feasibility of the business users. I am trying to achieve this by using master calendar but I'm finding it baffling how using the master calendar take me from three dates into one date so I can make a month out of that desired date.

Thanks,

The answer to this post may help with creating a solution:

Using Multiple Dates With Master Calendar

Essentially, you create a table that links all of your dates to your master calendar.

Hope that Helps!

Yes all those three dates are in one table.

What do you mean by keyfield? Below please find my illustration of the description you provided. If I was to give all of them Date and Month alias wouldn't it give an error showing duplicate names in the same table.

link:

keyfield,

d2.linecanceldate as Date,

Month(d2.linecanceldate) as Month,

'Cancel' as Type

from contract;

concatenate (link)

keyfield,

lastbilldate as Date,

Month(d2.lastbilldate) as Month,

'End' as Type

from contract;

concatenate (link)

keyfield,

linestartDate as Date,

Month(d2.linestartDate) as Month,

'Start' as Type

from contract;

Thanks,

you could create a link table for the same and then combine the new date with the master calendar

link:

keyfield,

d2.linecanceldate as Date,

'Cancel' as Type

from contract;

concatenate (link)

keyfield,

lastbilldate as Date,

'End' as Type

from contract;

concatenate (link)

keyfield,

linestartDate as Date,

'Start' as Type

from contract;

in your master calendar rename the Date column as the Date that should link you data with the master calendar like

Master_Calendar:

LOAD date as Date,

...

....

NOTE:Make sure your master calendar date format and the linking date format are all same
