I am able to calculate how many employees are working using DAX measures:
Number of employees started := CALCULATE(COUNTA([Emp from]);FILTER(ALL(tDate[Date]);tDate[Date]<=MAX(tDate[Date]))) -
Number of employees quit := CALCULATE(COUNTA([Emp unitl]);FILTER(ALL(tDate[Date]);tDate[Date]<=MAX(tDate[Date])))
Number of employees working := [Number of employees started] - [Number of employees quit]
But I have not managed to calculate how many full time equivalent employees are working. Each employ has a workload from 0% to 100%.
How can I calculate the number of full time equivalent employees?
I have tried the following for number of full time equivalent employees started, but in contrast to the measures above it doesn't accumulate over time. It just shows the results for each individual month:
Number of full time equivalent employees started:=CALCULATE(SUMX(tEmployees;tEmployees[Workload]*Not(ISBLANK(tEmployees[Emp from])));FILTER(ALL(tDate[Date]);tDate[Date]<=MAX(tDate[date])))
Do you have any suggestion for how I can solve this?
You might try something like this. In your Emp table have the start date and end date for the employee. In your measure you would use the calculatetable function to create an in memory table that has one row for each date in your date table and each employee id. This same in memory table would take the work percentage and create a column that that represents the number of hours worked by that employee on that day. Then you just need to express number of 'equivalent' employees as: sum of number of hours worked/(number of hours in a 'full time work day' * count of days in period). This should give you a measure you can use along with your dates to find the number of full time equivalent employees in on any given day or over any given period.
See my sample table structure in this TechNet forum post. This is a modelling problem first, and a DAX problem second.
Once you've created your headcount fact, all of this becomes trivial.

I need to implement a measure that indicates sales volume per product per day. For the example table below (each line is a record of a sale):
id,create_date,report_date,quantity
329,2019-01-02 08:19:17,2019-01-02 14:34:12,6
243,2019-01-02 09:11:42,2019-01-03 15:30:14,6
238,2019-02-02 08:19:17,2019-03-02 14:36:17,2
170,2019-04-02 02:15:17,2019-04-02 14:37:12,2
238,2019-04-02 08:43:11,2019-04-02 14:41:01,8
238,2019-04-02 08:52:52,2019-04-02 14:39:12,1
238,2019-08-02 08:10:09,2019-08-02 15:02:12,1
238,2019-10-02 08:10:17,2019-10-02 18:34:11,1
170,2020-01-02 08:24:14,2020-01-02 19:31:31,2
170,2020-01-02 08:32:16,2020-01-02 21:52:32,3
The operations to reach the result:
1. Identify total sales and total products for each day.
For 2019-01-02, two sales were carried out, totaling 12 products (6 products for each sale on the day)
2. Divide total products by total sales, resulting in the product/sale ratio for the day (if the result is 2, it indicates that each sale on average corresponds to two products).
In the example table there are 6 different dates (YYYMMDD), for each corresponding date: total products/amount of sales on the day (12/2, 2/1, 11/3, 1/1, 1/1, 5/1) .
3. Average every day's story, resulting in a single value.
(3 + 2 + 3.6 + 1 + 1 + 3)/6 = 2.26 , indicating that on average two products are sold per sale per day.
As it involves many operations, I couldn't get a solution for this problem. If anyone can help me.
note: I accept alternative suggestions to offer the measure to indicate the volume of sales per product per day.
Please check the numbers given in your steps 2 and 3:
12/2=6 not 3
5/1 must be 5/2
I still think that you want to calculate a 'day story' in step 2, see formular below.
Here are the steps for generating such a value:
create a table
add your time as dimension and make it to date not date&time
order by date ascending (optional)
create a field day story with the formula sum(quantity)/count(id)
add this field three times to your table
click on the AUT left to the fieldname and select Running calculation to 'running average`
You have to convince your users to only look at the last line of the table.
all:
I am trying to design a shared worksheet that measures salespeople performance over a period of time. In addition to calculating # of units, sales price, and profit, I am trying to calculate how many new account were sold in the month (ideally, I'd like to be able to change the timeframe so I can calculate larger time periods like quarter, year etc').
In essence, I want to find out if a customer was sold to in the 12 months before the present month, and if not, that I will see the customer number and the salesperson who sold them.
So far, I was able to calculate that by adding three columns that each calculate a part of the process (see screenshot below):
Column H (SoldLastYear) - Shows customers that were sold in the year before this current month: =IF(AND(B2>=(TODAY()-365),B2<(TODAY()-DAY(TODAY())+1)),D2,"")
Column I (SoldNow) - Shows the customers that were sold this month, and if they are NOT found in column H, show "New Cust": =IFNA(IF(B2>TODAY()-DAY(TODAY()),VLOOKUP(D2,H:H,1,FALSE),""),"New Cust")
Column J (NewCust) - If Column I shows "New Cust", show me the customer number: =IF(I2="New Cust",D2,"")
Column K (SalesName) - if Column I shows "New Cust", show me the salesperson name: =IF(I2="New Cust",C2,"")
Does anyone have an idea how I can make this more efficient? Could an array formula work here or will it be stuck in a loop since its referring to other lines in the same column?
Any help would be appreciated!!
EDIT: Here is what Im trying to achieve:
Instead of:
having Column H showing me what was sold in the 12 months before the 1st day of the current month (for today's date: 8/1/19-7/31/20);
Having Column I showing me what was sold in August 2020; and
Column I searching column H to see if that customer was sold in the timeframe specified in Column H
I want to have one column that does all three: One column that flags all sales made for the last 12 months from the beginning of the current month (so, 8/1/19 to 8/27/20), then compares sales made in current month (august) with the sales made before it, and lets me know the first time a customer shows up in current month IF it doesn't appear in the 12 months prior --> finds the new customers after a dormant period of 12 months.
Im really just trying to find a way to make the formula better and less-resource consuming. With a large dataset, the three columns (copied a few times for different timeframes) really slow down Excel...
Here is an example of the end result:

This should be simple so I think I am missing it. I have a simple line chart that shows Users per day over 28 days (X axis is date, Y axis is number of users). I am using hard-coded 28 days here just to get it to work.
I want to add a scorecard for average daily users over the 28 day time frame. I tried to use a calculated field AVG(Users) but this shows an error for re-aggregating an aggregated value. Then I tried Users/28, but the result oddly is the value of Users for today. The division seems to be completely ignored.
What is the best way to show average number of daily users over a time frame? Average daily users over 10 days, 20 day, etc.
Try to create a new metric that counts the dates eg
Count of Date = COUNT(Date) or
Count of Date = COUNT_DISTINCT(Date) in case you have duplicated dates
Then create another metric for average users
Users AVG = (Users / Count of Date)
The average depends on the timeframe you have selected. If you are selecting the last 28 days the average is for those 28 days (dates), if you filter 20 days the average is for those 20 days etc.
Hope that helps.
I have been able to do this in an extremely crude and ugly manner using Google Sheets as a means to do the calculation and serve as a data source for Data studio.
This may be useful for other people trying to do the same thing. This assumes you know how to work with GA data in Sheets and are starting with a Report Configuration. There must be a better way.
Example for Average Number of Daily Users over the last 7 days:
Edit the Report Configuration fields:
Report Name: create one report per day, in this case 7 reports. Name them (for example) Users-1 through Users-7. These are your Row 2 values. You'll have 7 columns, with the first report name in column B.
Start Date and End Date: use TODAY()-X where X is the number of days previous to define the start and end dates for each report. Each report will contain the user count for one day. Report Users-1 will use TODAY()-1 for start and end, etc.
Metrics: enter the metrics e.g. ga:users and ga:new users
Create the reports
Use 'Run reports' to have the result sheets created and populated.
Create a sheet for an interim data set you will use as the basis for the average calculation. The first column is date, the remaining columns are for the metrics, in this case Users and New Users.
Populate the interim data set with the dates and values. You will reference the Report Configuration to get the dates, and you will pull the metrics from each of the individual reports. At this stage you have a sheet with date in first columns and values in subsequent columns with a row for each day's values. Be sure to use a header.
Finally, create a sheet that averages the values in the interim data set. This sheet will have a column for each metric, with one value per column. The one value is calculated from the series in the interim data set, for example =AVG(interim_sheet_reference:range) or any other calculation you'd like to do.
At last, you can use Data Studio to connect to this data source and use the values. For counts of users such as this example, you would use Sum as the aggregation field type when you are creating the data source.
It's super ugly but it works.
Background Information: We have an incident time tracker that tracks how long each user spends with a representative before the issue can be closed. We want to determine the average volume of incidents that are being handled for each hour. To say this in another way: We want to get an hourly baseline for each day of the week that will show us the average total call length within the specific time period. Eg: We want to average the total length of every call on Monday from 9AM-10AM for all the weeks in the database, and the same for other hourly intervals.
The simplest way to think of this is that I want AVG(SUM) for the specific time periods, but Tableau does not allow me to do this.

SQL Query:
I have written a SQL query that returns the answer:
We are looking at two columns: start_time (time stamp) and interval_seconds(float)
In the inner query I use the hour_start function which truncates the date/time value to the hour start, so I can group by the hour and day of the week in the outer query.
SQL Results:
Question:
Is there a way to solve this problem ENTIRELY in Tableau that would get me the result that I am looking for without having to write any SQL code?

You can use Level of Detail expressions to compute the SUM(interval_seconds) at the hour level and then use AVG to calculate the number you are looking for.
I created a couple of calculations:
hour which is defined as: DATETRUNC('hour',[start_time])
this should be equivalent to your hour_start(start_time).
and interval_hours which is defined as {FIXED [hour] : SUM([interval_seconds])/3600 }
This calculates the aggregate for each start_time truncated to the hour.
After this, you simply calculate AVG(interval_hours) and use it in your view.

Although the chart looks similar to yours, the numbers I came up with are somewhat different from the "SQL Results" you show. Was the data you provided slightly different?
I need to calculate how much a plan has cost the customer in a specific month.
Plans have floating billing cycles of a month's length - for example a billing cycle can run from '2014-04-16' to '2014-05-16'.
I know the start date of a plan, and the end date can either be a specific date or NULL if the plan is still running.
If the end date is not null, then the customer is charged for a whole month - not pro rated. Example: The billing cycle is going from the 4th to 4th each month, but the customer ends his plan on the 10th, he will still be charged until the 4th next month.
Can anyone help me? I feel like I've been going over this a million times, and just can't figure it out.
Variables I have:
#planStartDate [Plan's start date]
#planEndDate [Plan's end date - can be null]
#billStartDate [The bill's start date - example: 2015-02-01]
#billEndDate [One month after bill's start date - 2015-03-01]
#price [the plan's price per billing cycle]
Heres the best answer I can give based on the very small information you have given so far(btw, in the future, it would really help people answer your question faster/easier/more efficiently if you could specify a lot more info;tables involved, all columns, etc..):
"I need to calculate how much a plan has cost the customer in a specific month."
SELECT SUM(price), customerID(I assume you have a column of some sort in this table to distinguish between customers) FROM table_foo
where planStartDate BETWEEN = 'a specific date you specify'
Its a bit rough of a query, but thats the best I can give till you specify more clearly your variable (i.e. tables involved, ALL columns in table, etc etc.....)
