Delivery should not created until schedule line quantity in STO is fulfilled

Dear All,

Could anyone please help me on this

My requirement is that delievry should not be able to creat/should be blocked until the full quantity in the scedule line in STO is firmed/committed.

Is there any indicator or SPRO settings that drives this in STO to accomplish this without doing any code changes ?

your help is much appreciated.

Kind regards,

Rahul.
