Get Previous Running Total for Missing Month
Hi All,
Let say I have two tables like below, I want to make accumulative line graph of which line should always increase.
The 'Date' table and 'ShipQty' table has relation in date column.
X axis: Date, Y axis: Qty
'Date'
| Date |
| 2001-01-01 |
| 2001-01-02 |
| 2001-01-03 |
| ~ |
| 2022-12-30 |
| 2022-12-31 |
'ShipQty' - (Qty is MTD value)
| Item | Date | Qty |
| A | 2019-05-01 | 30 |
| A | 2019-08-01 | 5 |
| A | 2019-10-01 | 15 |
| B | 2003-12-01 | 10 |
| B | 2004-01-01 | 50 |
| B | 2004-03-01 | 20 |
| B | 2004-04-01 | 30 |
| C | 2020-11-01 | 5 |
| C | 2021-01-01 | 15 |
| C | 2021-02-01 | 10 |
How can I get previous running total for missing month of each item?
The result should be like below.
'Running Total' - (Should not have missing month.)
The records in red should be inserted with previous qty and missing month.
The Qty values in blue should be the result of sum of previous value and current month.
| Item | Date | Qty |
| A | 2019-05-01 | 30 |
| A | 2019-06-01 | 30(Previous value) |
| A | 2019-07-01 | 30(Previous value) |
| A | 2019-08-01 | 35(30+5) |
| A | 2019-09-01 | 35(Previous value) |
| A | 2019-10-01 | 50(35+15) |
| B | 2003-12-01 | 10 |
| B | 2004-01-01 | 60(10+50) |
| B | 2004-02-01 | 60(Previous value) |
| B | 2004-03-01 | 80(20+60) |
| B | 2004-04-01 | 110(30+80) |
| C | 2020-11-01 | 5 |
| C | 2020-12-01 | 5(Previous value) |
| C | 2021-01-01 | 20(15+5) |
| C | 2021-02-01 | 30(10+20) |
Please kindly help me.
Thanks in advance.
Hi Anonymous ,
You could create a calendat table (2019/1/~2022/12/21)
calendar = CALENDAR(date(2019,1,1), date(2022,12,31))then create relationship between calendar and fact table, and use measure and calendar in table like below,
Measure = var maxd=CALCULATE(MAX('Table'[Date]), ALLEXCEPT('Table','Table'[Item])) return CALCULATE(SUM('Table'[ Qty]), FILTER(ALLSELECTED('calendar'), 'calendar'[Date]<=MIN('calendar'[Date]) && MIN('calendar'[Date])<=maxd))It will show all months in each year, and end with the max month in fact table. You could refer to my sample for details.

Thanks VijayP
I checked your file but one thing that I wonder is how could you make every month in "table".
Because in my case, there is no row for missing value, even month value.
The hard thing is insert missing month row if it is missed.
For example my table looks below, I should create April.
(Sorry for Date language...)
