Budget control during PR05 /TRIP

Dear sapient

Client have two different server i.e HR & Travel management have been configured in one server and main sever where FI & other respective module have been configured including funds management. so client requirement is budget control should be there during the time of travel request creation (PR05/TRIP). kindly let me know how to activate budget control through funds management as both are in different server.

We are using EHP6 version and fund management already activated and working fine.

Thanks Regards
