This depends on the testing side and how often you wish to check on the material.
Please read up and research dynamic modification rules. This sounds like it might fit your requirement. With DMR you inspect a certain number of shipments. If they pass, you allow future shipments to go directly to unrestricted inventory. After so many skips or so many days, you reinspect a shipment. If it passes, you can go back to skipping. This can be repeated as long as you want.
Welcome to QM and the SCN forum. Please make sure you read the rules of engagement. We do expect questions to be researched PRIOR to posting.
There is considerable amount of information available on "skip lots" and "DMR" already here in SCN and elsewhere. The SAP help files also have a lot of info on it. And don't be afraid to use that F1 key when your trying things in SAP.
