Correlation Matrix Power BI

[Anonymous]

Hello all,
I would like to know if anyone could help me with a challenge I have been facing in my company.
I need to implement a correlation matrix in Power BI, to know who works with whom, if workers have more than two hours of work in common. For example, if I had worked with Jhon for 3 hours this year, in this matrix I should appear with the number 3 when correlated with Jhon.
Could anyone help me with this challenge or provide a link to a tutorial?
Thanks in advance guys. You are the best.

Hi @Anonymous ,

I would imagine in professional firms everyone keeps his/her time sheets entering the project codes to account for his/her hours to indicate which projects/ engagements they worked on.  Does your company have such timesheet records in the ERP system?   I'd like to find out how the timesheets are maintained to gain understanding of how to solve your problem.  

Best regards,
