Where is the control of different tabs on Business Partner(BP) on S4 Hana?

Hello Experts,

I was creating BP and so customer master in BP transaction. What I have noticed in BP role is some of the tabs are not available for other Role.

For example, for customer there were two business roles FLCU00 - FI customer & FLCU01 - FI customer 1. When I choose FLCU00, sales area tab disappears but available for FLCU01.

It might be basic question but where do we maintain that settings to have the fields/tabs available? ( For XD01 it is controlled by account group but not sure in BP transaction)

Thanks,

Jay
