FICO Configuration- Company code & controlling area

Hi,

Can anyone be of assistance. I have just created a new company code and configured all the relevant GL codes etc. For some strange reason, each time I run transaction FB50 and others, the system notifies me that controlling area is not assigned to company code.

Because its a new configuration, I deactivated document splitting since I have not configured controlling as yet.

can some one help.?

Thank you.
