Inter-company GL entry with each Bank Transfer

Dear,

we are doing the bank transfers from bank account to another bank account and both of the bank accounts under the same operating unit. but system create the following GL entries which is one of the additonal entry related to the inter company.

1)

DR "To Bank Account"

     CR "From Bank Account"

2)

DR "Inter company Receivable account"

     CR "Inter company Payable account"

Please advise why system is creating a inter company entry with each bank transfer and how to resolve this issue.

Thanks
