Relation between ProjPostTransView and PurchOrder

Add the ProjTransId in to that view from ProjItemTrans.

display PurchId PurchId()
{
    PurchLine       PurchLine;
    ProjItemTransView   projItemTransView;
    InventTransOrigin       inventTransOrigin;
    ProjItemTrans           projItemTrans;
    ;
    if(this.ProjTransId)
    {
        select projItemTrans where projItemTrans.ProjTransId == this.ProjTransId;
        select PurchLine where PurchLine.ProjTransId == projItemTrans.ProjTransIdRef
                                        && PurchLine.ItemId == projItemTrans.ItemId;
        //select InventTransId from projItemTransView where projItemTransView.ProjTransId == this.ProjTransId
        //join inventTransOrigin where inventTransOrigin.InventTransId == projItemTransView.InventTransId;
        return PurchLine.PurchId;
    }
    else return “”;
}

Thanks,
