Correct, the original error is you crediting salaries.

If you are using the journal -
DEBIT - Salaries
Credit - Loan Account

Journal is the only method from an accounting perspective. Dont forget the UIF payment!!!(which you can do as a cheque payment which will be simpler than a journal. if you want to do journal then transaction is -
Debit = Salaries Full amount(R6000)
Credit - Loan person A (R3000)
Credit - Loan person b (R3000)
Debit - Payroll Burden:UIF (60) this is an expense account
Debit - Loan person a (R30)
Debit - Loan person b (R30)
Credit - bank (R120)
You can however do the journal and then save it. Therefore each month it can be automated or various options (Do a journakl entry, then before saving, GOTO edit, select memorize journal entry and follow the list)

The transfer funds is for any form of bank accounts, eg. Cheque account to petty cash. Or Bank to credit card etc, etc.
