The deleteItem method implies you want to delete the method from all collections it lives in so I would not use that at all to remove the item from a group. Usually, there is a property on the item itself which indicates which group it is in. You might just set that property to null and commit that change. If you have autoRefresh enabled for your fills, they would be reinvoked to refresh their contents. The first one would still return the item, but the second one would no longer return the item because the item's group property was not set to that value anymore. This assumes that the fill to retrieve a group's members is made on a query against properties on the item in the group.
It is also possible that the group membership is maintained by some separate table which is not part of the state of the item in the group. In this case, the other way you can do this is to implement the flex.data.assemblers.Assembler interface (if you are not already) and override the "removeItemFromFill" method. Then on the client, you just remove the item from the second collection using one of the ArrayCollection.removeItem or removeItemAt methods. When you commit, your Assembler.removeItemFromFill method should be called which you can use to update that other table.
