Missing Sales Area

CREDIT MANAGEMENT CONFIG

I am about to assign the credit control area to the sales area but when I open OVFL, the sales are of my company is not appearing. I am pretty sure I have the sales area configured because I assigned my sales office to that sales area.

The credit control is defined already (OB45).

The assignment of credit control to company code is done too (OBY6).

What is the cause of my issue? Is there anything I missed? As far as I know, the sales area on OVFL is automatically populated and I do not need to populate it. There is no way I can manually put sales area too.

Please help.
