How can I use GL expense allocation from inventory miscellaneous transaction account 's amount in OP

Hi

  I 'm plan to use expense allocation feature to allocate amount from GL Account to finished goods item. My problem is some account is no amount until I run create accounting and post it to GL. For example ,I issue item AA with miscellaneous transaction to account 5501. I need to allocate this account 's amount to some finished goods items. How can I meet this requirement?
