How can we find the purchasing group code with User ID

Hello Friend.

I have some questions.

I made the org plan for purchasing department and assign the purchasing group' backend system to created org.

And then, i created user with buyer role and assign user to purchasing group org.

I want to find the purchasign group code using user id.

-Which table has the purchasign group code?

-Can we find out the purchasing group code with user ID?

Thank you,

Best Regards,

SH
