I am complete new user in tableau. Despite great presentations I got to do, I am totally lost when it comes to create calculated fields.
Here is my issue. On a monthly basis, based on historical sales and promotion prices, I have to determine an Actual Selling Price to be compare with actual data. Find enclose the current calculation I did in Excel in blue.
This is pretty straight forward in Excel but translating in tableau is quite a challange especially using date.
