Merge, Add, Subtotal, Filter by User

[S2]

I'm a rookier Power BI user.

My desired outcome: Total number of reports. Total number of reports for each author that includes when they coauthored. I want to filter by author that calculates the author's total without adding to the total reports. 

Here's my table:

Author	Report Types	CoAuthor1	CoAuthor2
Tom	A1	Betty
Betty	A2
Debbie	A4
Debbie	A5	Tom	Juan
Tom	A9
Juan	A1
Juan	A3	Mary
Bob	A2
Mary	A2	Debbie	Bob

@S2 , I think you can unpivot the table and use that

Don't @S2,

According to your requirements, I tried one of the simplest methods, which can be used as a reference: create three measures to count the number of Author, CoAuthor1, and CoAuthor2 columns. Create another table and accumulate the obtained number.

Measure1 = 
CALCULATE(
    DISTINCTCOUNT('Table'[Report Types]),
    ALLEXCEPT('Table', 'Table'[Author])
)

Measure 2 = 
CALCULATE(
    DISTINCTCOUNT('Table'[Report Types]),
    ALLEXCEPT('Table', 'Table'[CoAuthor1]),
    FILTER( 'Table', [CoAuthor1] <> BLANK() )
)

Measure 3 = 
CALCULATE(
    DISTINCTCOUNT('Table'[Report Types]),
    ALLEXCEPT('Table', 'Table'[CoAuthor2]),
    FILTER( 'Table', [CoAuthor2] <> BLANK() )
)

Put the measurement in the table:

Create a new table and add the Sum_Author:

Table 2 = 
VAR t1 = 
SUMMARIZE(
    'Table', [Author],
    "R", [Measure1]
)
VAR t2 = 
SUMMARIZE(
    'Table', [CoAuthor1],
    "R", [Measure 2]
)
VAR t3 = 
SUMMARIZE(
    'Table', [CoAuthor2],
    "R", [Measure 3]
)
RETURN
UNION(
    t1, t2, t3
)

If the problem is not yet resolved, provide detailed information about the error and let me know immediately, waiting for your response.

So I did try that but when I filtered using a slicer the authors were referencing coauthors.  For example, when selecting Bob, Mary's reports will be calculated.  Any idea what I'm doing wrong?  Also, would you recommend merging or appending the columns? 

Thank you.
