Operation Confirmation

Hi Friends,

I have a typical requirment from client side.

For a mining material production , each month one production order will created ,

and daily Partial confiramtions are carried out .

Confirmation contains 6 operation . which are taking place in parallel mode.

per shift wise want confiramtion for all the 6 operation . we are using milestone confiramtion key. i.e if operation 10 is confirmed then operation 20 is allowed for confiramtion.

But if i create Production order and only first time it gives sequencial wise conframtion ,

if confirmation 2 time frm 1 st to 6 it will not give the sequence the error means if i without confirming 10 it is possible to confirm 20.

how to overcome this problem

urgent requirement points r definately rewarded.

regard
