Add value to a given Time Duration

mohitveer_sandhu

Hi,

 

I have a Module A with the following line items, format, and data:

value(Format = Number)	start(Format = Date (mm/dd/yyyy))	end(Format = Date (mm/dd/yyyy))
101	1/1/2019	2/1/2019
201	3/1/2019	4/1/2020
301	5/1/2020	blank

 

I have another module B with Time Dimension and a Line item - value_over_months that will be mapped to module A and expected data to be as given below:

	Jan-2019	Feb-19	Mar-19	Apr-19	May-19	Jun-19	Jul-19	Aug-19	Sep-19	Oct-19	Nov-19	Dec-19	Jan-20	Feb-20	Mar-20	Apr-20	May-20	Jun-20	Jul-20	Aug-20	Sep-20	Oct-20	Nov-20	Dec-20
value_over_months	101	101	201	201	201	201	201	201	201	201	201	201	201	201	201	201	301	301	301	301	301	301	301	301

 

How can I achieve this?

So the requirements have changed since the original post?   The best way to do this is to fix the data at the source so you are only loading the correct values that you need.

 

With that said, I believe this will work:

 

In the first module, create these new line items.

Real Starting Month: period(start(date))

New Starting Month: IF PERIOD(Start Date) <> PERIOD(End Date) THEN Real Starting Month + 1 ELSE Real Starting Month

Days: IF End Date <= 'SYS Time Filter - Month'.End[LOOKUP: Real Starting Month] THEN End Date - Start Date ELSE 'SYS Time Filter - Month'.End[LOOKUP: New Starting Month] - Start Date

Month to Use: leave blank for now

 

Create a new module dimensionalized by Time:

Max: Data of Numbered LIst.Days[MAX: Data of Numbered LIst.New Starting Month]

 

Go back to the "data" module and fill in the Month to Use formula:

IF Days = Max Nbr of Days.Max[LOOKUP: New Starting Month] THEN New Starting Month ELSE BLANK

 

 

 

In the target module, change the original sum to now use Month to Use:

 

 

Hope this works for you,

Hi @mohitveer_sandhu,

You can add the time (month) in the same dimension as module A. On the formula, you can try something like if the month (time) is between start and end get the item(value) else blank. Handle the summary, you can use (for eg.) max. Then reference it in your module B.

I hope this helps you out.

Can you elaborate on how can I add time(month) in module A?

And also I have a restriction that module A can have only this schema.

See if this helps.

 

I have replicated your data, but changed the years to fit my model:

 

 

In the target module, I have these two line items:

Value: Data of Numbered LIst.Value[SUM: Data of Numbered LIst.Start Date] where Data Of Numbered List is the name of the source module (the one above)

Value Over Months:IF Value = 0 THEN PREVIOUS(value over months) ELSE Value

 

 

 

 

Hope this works for you,

@rob_marshall Thanks, will try this.

This works but if we want to extend this to such a data where for a single month there can be multiple values and we want to take only the value that’s true for the majority of the month.

 

For example:

value	start date	end date
101	1/1/2019	1/4/2019
102	1/5/2019	1/20/2019
103	1/21/2019	2/28/2019

 

Module B should have

	Jan-20	Feb-20	----
value	102	103	----
