Hello,
We have employees that work in multiple departments and fulfill multiple roles. How can I reflect this in the ERP?
Thank you,
Sofia
Good question 
I think each one of us carry multiple role & responsibilities in a company. Multiple choice in department for an employee may lead to some issue if I’m correct but you can customize it as per your requirement.
In general, we map an employee with one dept. and maintain a profile(role and responsibilities) for them.
