Loan Paid from one company and paid back into another

Good day,

I require some assistance with a client.

The client has 2 companies A and B:

- A short-term Loan was made to an employee from company A

- Employee paid the loan back the Company, But into Company B

I work on both companies books, but in one company I have a loan Credit and in the other a Loan Debit.

How do I get these to reflect on the books of the Company from which the payment has been made originally?  I would like to streamline these so that we can pick up quickly if a loan was repaid or not.

Do I do a Journal entry for both Companies?  And if so - how would I do this?

Thanks!!!!
