Determining Sales Based on a Certain Day's Sales Volume

Preview

View the daily sales compared to the sales of a fixed day based on the sales of a certain day. For example, you want to view the comparison between the daily sales and the sales of the first day of a month.

In addition, based on the sales of a certain commodity, you can determine the sales of other commodities according to the ratio between other commodities and a fixed commodity.

Implementation Method

Calculate the sales volume of the first day of a month and the ratio through data analysis.

Take the data table Store Sales Statistics in Public Data > Department Data > Sales as an example.

Calculating the Ratio

Create an analysis subject, add Store Sales Statistics, click Field Settings, and tick the fields Sales Data and Sales Volume.

1. Create a Group Summary, drag the field Sales Date twice into Group, and drag the field Sales Volume into Summary.

2. Rename the first Sales Date to Year-Month and select Year Month for date grouping.

Click Formula Column, set a column name to Based on the First Day of a Month, and enter the formula IF(DAY(Sales Date)=1,Sales Amount,0).

In the column Based on the First Day of a Month, there is sales data on the  first day of each month, and sales data on the rest days are all 0.

In the column Based on the First Day of a Month, the rest data are all 0 (except for the data on  the first day of each month). So when you sum up the field Based on the First Day of a Month for each month, the obtained sales volume is always the sales volume of the first day of  each month.

Click OK and you can view that the data in the field Sales Volume in Early Month is always the data of the first day of each month.

Calculate the value of Sales Volume / Sales Volume in Early Month.

Demonstration

The ratio of the daily sales volume tothe sales volume of the first day of each month is shown in the following figure.
