For the Item-Item stock transfers, the only GL accounts that are updated are the IC Control and the AP clearing accounts. Neither would be related to costs for subcontracting. Though the extra costs (there are 2; either pro-rated or on the detail) could be exactly what the sub-contract was for, the function probably is not updating the accounts you'd require.

I think that PlusCommunity may be able to give you another solution (ie a UniDevCo add-on product or such).
