Calculating Audit Completions over time from Changing Roster of Employees

[bigchippah]

Hello,

I am trying to calculate the number/percentage of audits of a team as they are audited over a time period.  I have been struggling with an efficient way to accomplish this task and I'm not making any more progress.  I apologize in advance, because this is a long one.  Here's what I'm working with:

My sources:

• I receive a weekly list of current employees.  These are saved in a OneDrive folder and merged in PowerQuery to give me an overall roster of employees from week to week.
• Employees are audited for food safety at various times through the month.  The list of audits are received as a spreadsheet weekly.  This is a single file that is updated as audits are conducted.

Table 1. Employee Roster:

Date	Employee ID	Department
2/27	Employee1	Produce
2/27	Employee2	Produce
2/27	Employee3	Deli
2/27	Employee4	Deli
2/27	Employee5	Produce
2/27	Employee6	Bakery
2/27	Employee7	Bakery
2/20	Employee1	Produce
2/20	Employee2	Produce
2/20	Employee3	Deli
2/20	Employee8	Deli
2/20	Employee9	Deli
2/20	Employee10	Bakery

I have a measure to calculate the number of employees in each department.  I use COUNTROWS to return a roster size by department:

Measure Result - Department Employee Count:

Date	Department	# of Employees
2/27	Produce	3
2/27	Deli	2
2/27	Bakery	2
2/20	Produce	2
2/20	Deli	3
2/20	Bakery	1

These employees are periodically audited for cleanliness.

Table 2. Audit Results:

Date	Employee	Department	Result
2/27	Employee1	Produce	Pass
2/21	Employee4	Deli	Pass
2/20	Employee2	Produce	Pass
2/19	Employee8	Deli	Fail
2/15	Employee7	Bakery	Pass

My desired outcome:

• Be able to calculate weekly how many/percentage of employees of each department have been audited as the month progresses.
• If an employee is audited during the measuring period, I would like to remove them from the list of remaining employees

Slicers: Date Slicer (choose week/month/quarter)

Dates	Department	# of Employees (as of first date of measuring period)	Audited	Remaining
2/1 - 2/27	Deli	3	2	1
2/1 - 2/27	Bakery	2	1	1
2/1 - 2/27	Produce	3	1	2
2/1 - 2/19	Deli	3	1	2
2/1 - 2/19	Bakery	2	1	1
2/1 - 2/19	Produce	3	0	3

My challenge(s):

• Employee roster numbers change from week to week.  Week 1 (2/20) might have 6 employees, while Week 2 (has 7 employees).  I can't SUM my roster because some employees show up on both weeks.
• I can compromise by getting the roster sizes at the beginning of the measuring period (date of the first audit of the month) and using it as my constant. How can I get a COUNTROWS value for the earliest date in a dateslicer period?
• How can I compare my audited list to my initial roster and remove those who have been audited?

Thank you for reading, and thank you for any guidance you may be able to provide!

@Anonymous  Can you provide any more clarification on your proposed solution?  I would greatly appreciate it!

@AnonymousHello and thank you for the answer!  I'm trying to work my way through the steps and I've encountered a couple of error messages:
In the "Add a week and count to Audit Results" step, the following code:

count = COUNTX(FILTER(ALL('Audit Results'),'Audit Results'[week]=EARLIER('Audit Results'[week])&&'Audit Results'[Department]=EARLIER('Audit Results'[Department])),[Department])

returns an error that says, "EARLIER/EARLIEST refers to an earlier row context which doesn't exist."

Secondly, when I use this code:

Audited =
var _min=MINX(ALLSELECTED('Audit Results'),'Audit Results'[Date])
var _max=MaxX(ALLSELECTED('Audit Results'),'Audit Results'[Date])
return
CALCULATE(SUM('Audit Results'[Column]),FILTER(ALL('Audit Results'),MAX('Audit Results'[week])>=WEEKNUM(_min,1)&&MAX('Audit Results'[week])<=WEEKNUM(_max,1)&&'Audit Results'[Department]=MAX('Employee Roster'[Department])))

can you clarify which column 'Audit Results'[Column] should use? 

Thank you for your time and assistance!  I am very greatful!

Hi  @bigchippah ,

Here are the steps you can follow：

1. Create calculated table.

Table = CALENDAR(DATE(2022,1,1),DATE(2022,12,31))

2. Create calculated column.

Add a week and count to Audit Results:

week = WEEKNUM('Employee Roster'[Date],1)

count = COUNTX(FILTER(ALL('Audit Results'),'Audit Results'[week]=EARLIER('Audit Results'[week])&&'Audit Results'[Department]=EARLIER('Audit Results'[Department])),[Department])

Add a week to Employee Roster:

week = WEEKNUM('Employee Roster'[Date],1)

3. Create measure.

# of Employees =
var _min=MINX(ALLSELECTED('Audit Results'),'Audit Results'[Date])
var _max=MaxX(ALLSELECTED('Audit Results'),'Audit Results'[Date])
return
COUNTX(FILTER(ALL('Employee Roster'),
'Employee Roster'[week] >=WEEKNUM(_min,1)&&
'Employee Roster'[week] <=WEEKNUM(_max,1)&&
'Employee Roster'[Department]=MAX('Employee Roster'[Department])&&
'Employee Roster'[week]=MAX('Employee Roster'[week])
),[Department])

Audited =
var _min=MINX(ALLSELECTED('Audit Results'),'Audit Results'[Date])
var _max=MaxX(ALLSELECTED('Audit Results'),'Audit Results'[Date])
return
CALCULATE(SUM('Audit Results'[Column]),FILTER(ALL('Audit Results'),MAX('Audit Results'[week])>=WEEKNUM(_min,1)&&MAX('Audit Results'[week])<=WEEKNUM(_max,1)&&'Audit Results'[Department]=MAX('Employee Roster'[Department])))

4. Result:

Take the [Date] of the Table table as the slicer.
