To correct this entry.
1. I would set up either a Petty Cash or Cash account in the Bank.
2. The journal entry you mention I would have one side to the Loan account with the parent company and the other to the new cash account.
3. I would then pay the supper invoice to the cash account.
This will set up your loan account pay the supplier and you new cash account will be nil.
You can then use this cash account should you have further bills paid this way.
I hope this helps you
