When dissolution is started all assests accounts (except Cash/Ban) are transferred to the debit of Realization A/c. Similarly all liabilities are transferred to the credit of Realization A/c. Any free reserves/accummulated loses are credited/debited to partners' capital accounts. So only Bank A/c, Realization A/c and Partners' capital accounts remain open in the books. So if a creditor is handed over an asset, no entry is passed because neither creditors accoount or asset's account is open. So no journal entry can be passed. In the same journal entry, we cannot debit Realization A/c and credit Realization A/c.
What will happen if an asset is handed over to a creditor at 10% discount, how this discount will be recorded? Let us take an example, there is only one Machine of Rs.60000 and a creditor of Rs.54000. There are no other assets and liabilities. These will be journal entries:
1. Realization A/c Dr. 60000
To Machine A/c 60000
2. Creditors A/c Dr. 54000
To Realization A/c 54000
3. Partners' Capital A/c Dr 6000
To Realization A/c 6000
