AP Expense accrual account not getting cleared in internal dropshipment scenario

Hi all,
We had a case where for a "non costed" item in a internal dropshipment sales order, the material distribution shows that the intercompany accrual is going to expense account whereas when the AP invoice was generated, the distributions show that the inventory account is getting cleared. Is there a setup change that needs to be done to ensure that the same expense account gets cleared in the AP invoice?
Request clarification on this. Thanks in advance.

Regards,
Arun
