Calculation based on Custom calendar and non joined tables

Hi Gurus,

I need some pointer to complete analysis for below requirement .

Requirement:

We need to create a monthly trending report which shows Last month's data, adding upto 12 months. i.e.

Just say for Year 2023, the report should show ;

In the month of Jan-23 : data of Jan-22 to Dec-22
In the month of Feb-23 : data of Jan-23
In the month of Mar-23 : data of Jan-23 and Feb-23
In the month of Apr-23 : data of Jan-23, Feb-23 and Mar-23
..
..
In the month of Dec-23 : data of Jan-23,Feb-23,Mar-23,...., and Nov-23

Metrics used in the report;

a) Net Cost : transactions happened on a particular month ( month is calculated based on external calendar (custom, mentioned below)
b) Man Hour : No. of Man hours required to complete a Job (for example, for the month of Jan-23, Total Number of Man hours to complete all the Job started from 01/01/2023 till 01/31/2023; We have a direct DB column capturing this value (the DB table is joined with Standard Calendar table to calculate Man hours).

Required Report output (Pivot Table):

Row : Year
Column Name : Month Name
Measure :
a) Net Cost
b) DMH
c) Net Cost/DMH

For the month of Feb-23 :

Month Name	January
Year	Net Cost	DMH	Net Cost/DMH
2023	$4,660	481	$9.69

For the month of Mar-23 :

Month Name	January	February
Year	Net Cost	DMH	Net Cost/DMH	Net Cost	DMH	Net Cost/DMH
2023	$4,960	544	$9.12	$4,380	668	$6.56

Net Cost is calculated based on Custom calendar (For Feb-23, Net Cost is calculated as sum of column NET_COST (table B) for the dates between 01/03/2023 and 02/01/2023 (including both dates) and for Mar-23 , Net Cost is calculated as sum of column NET_COST (table B) for the dates between 02/02/2023 and 03/01/2023 (including both dates)

Note: There is no joins available between Table A and Table B.

Please let me know, if you need any information.

P.S : I am facing issue while combining metrics and both column using different calendars to calculate months

Why can't you use a range join condition between tables A and B ?

Thanks @RADSr for the feedback but I can't use the join between Table A and Table B as both tables is joined individually with 2 different calendar table ( table A is joined with Standard Calendar table whereas table B is joined with Custom Calendar table).

Let me know, if more clarity is required.

How about creating an MV master calendar table w/ calendar_date as the key, calendar_month, custom_calendar_month, etc as the attributes.

That way any given transaction date ( actual or first of month/ last of month ) can roll up into either a calendar or custom month -- you can use CASE logic to present and calculate based on the dates for either grouping.

Hi @RADSr , after creating the MV table, the dates which were not overlapping (i.e for the given example, For the month of Feb, date 01/01/2023, 01/02/2023 is missing if I use standard calendar month name (for calculating Net Cost) and Date 02/01/2023 is missing, if I use the custom calendar's month name (for calculating DMH).

Or am I missing something here?

(I am attaching the MV query, which I used to create Calendar table)
