Change Usage Decision

Hi erybody.

I need to change the Inspection Stage for several Inspection Lots. But this Field is disable.

This is my scenario.

Problem:

1. The supplier create ASN's with lead time around 6 weeks. This

material is shipped by sea.

2. The inspection lot is created with actual Inspection Stage

(IMR). "Skip Lot Automatic"

3. Several Inspection Lots were created by the same way

4. The last Inspection Lot is created urgently and is shipped by air.

5. For the last Inspection Lot was made the Good Receipt from the

warehouse.

6. The material is rejected in Production Line.

7. The quality level is changed in order to check all the pending

Deliveries.

8. But for all lots that was created the Inspection Stage is not

changed.

How can I change the Inspection Stage for pending Deliveries?

Thanks in advance.
