Dealing with inserted parts in EPDM

Is anybody else using Inserted parts with EPDM? We're just starting with it and use the insert part command to insert casting into a second part file to perform the machining operations. We're having trouble when we have the parent at a state that a workflow state where it can't be checked out it won't allow the children to be checked in. Has anybody else had this trouble?SolidworksSolidworks Pdm enterprise Pdm
