how to restrict the usage decision

Hello To All,

I have a semi finished material. In Material Master (QM view), I have selected 04 inspection type, and maintained the Average Inspection Duration to be 20 days.

Now my question is , how to prevent end user to release Inspection lot by accident /mistake before the specified date?

SAP should not allow to release it before 20 days.

can someone please guide on this.

Thanks.
