Default controlling area is wrong in KSCF and KOCF t-code

Hello Experts,

We need to carry forward commitments on internal orders and cost centres into the next financial year

The transactions we use are KOCF and KSCF,

The default Controlling Area is appearing as 0001, but it should be 1000. The system is not allowing them to change it to 1000

Please can any body advice how it will be changed

Thanks Regards
