Case 24.

Tableau has many cumulative functions: RUNNING_SUM, RUNNING_MAX, RUNNING_AVG, and others. But among them, there is no such function as RUNNING_PRODUCT, which can often use to calculate indicators. But there is a way to implement it yourself.

- Calculate the total product of a given data set. For example, you could use this function in a sales report to calculate the total amount of items sold in a given period.
- Calculate the average product of a given data set. For example, you could use this function to calculate the average number of items sold in an online store over a given period.

- Analyze the performance of a given product over time. For example, you could use this function to compare the sales of a product across different stores or periods.
