Hello Anish,
There is enough information available in SCN forums on TECO status of the order.
TECO means order is completely executed from logistics point of view.
IMPACT:-
Goods movt are not allowed for the order. Changes are not allowed to the order. All Finance period end activities can be completed if TECO is put on the order.
Further the order is not considered for MRP run and stock requirement list doesn show this order as the capacity and material reservations against the order are deleted.
Thanks
Sahil
