Calculating Average Monthly Quantity
I've data that contains orders from customers along with quantities of each item.
I wish to calculate the monthly average of each material per customer. I tried to use the average function but the numbers didn't add up properly.
I'm trying to generate report similar to this one
| Material# | Material Description | Customer | Average Monthly Quantity |
| 123456 | Pencils | Staples | |
| 123456 | Pencils | Walmart | |
| 123456 | Pencils | Costco | |
| 654789 | Sharpner | Staples | |
| 654789 | Sharpner | Walmart | |
| 654789 | Sharpner | Costco | |
| 987456 | Ink | Staples | |
| 987456 | Ink | Walmart | |
| 987456 | Ink | Costco |
My Sample Data looks like this
| Date | Material# | Material Description | Customer | Quantity |
| 1/1/2021 | 123456 | Pencils | Staples | 100 |
| 1/1/2021 | 654789 | Sharpner | Walmart | 400 |

Try the following:
1) Create a date table:
Date = VAR EarliestYear = YEAR ( MIN ( Sales[Date] ) ) VAR LatestYear = YEAR ( MAX ( Sales[Date] ) ) RETURN ADDCOLUMNS ( CALENDAR ( DATE ( EarliestYear, 1, 1 ), DATE ( LatestYear, 31, 12 ) ), "Month", DATE ( YEAR ( [Date] ), MONTH ( [Date] ), 1 ) //Format as mmmm YYYY )2) Set column types as date for both and format Month as mmmm YYYY
3) Mark it as a date table.
4) Create relationship to your main table (I called mine Sales)
5) Create a measure in the main table:
Average Monthly Quantity = AVERAGEX ( VALUES ( 'Date'[Month] ), CALCULATE ( SUM ( Sales[Quantity] ) ) )6) Use it in a table visual:
