var qu= ii in db.inventoryitems                                                             join p in db.products                                       on ii.productid equals p.productid pgroup                                 mr in pgroup.defaultifempty()                                  join u in db.units                                      on mr.unitid equals u.unitid ugroup                                 ur in ugroup.defaultifempty()                                  join c in db.categories                                      on mr.defaultcategoryid equals c.categoryid cgroup                                 cr in cgroup.defaultifempty()                                 mr.activestatus == 1 && mr.organizationid == orgid && ii.activestatus == 1
