How to perform manuel entry using alternative chart of account?

Hi,

I'm in the situation where I have a global chart of account as operational COA for all the company codes. But some of those companies need to perform accounting documents direct entry in FI, using their own alternative COA (mapped with the global one at the account level).

How can I replace the operational COA by the alternative COA in the FI entry screens (example: FB01), for a defined company code?

Thanks
