Hello Reenu John,
FS-CML (Loans Module) does not work with cross-company code loans. We have no mirroring solution for this.
The only possible solution to achieve this would be to develop your own program that would call our BAPI BAPI_LOAN_CONTRACT_CREATE so that the opposite loan would be created according to your own logic.
I regret not being able to provide you with a more positive reply regarding the use of the Loans Module. I hope the provided information is of some help.
Many greetings,
Daniel Longoni
