Inspection and skip inspection based on time

Hi,

I have a requirement like below.

Raw material is received from material from vendor. First 15 days inspection to be carried out for all the receipts. Once the 15 days are over from the first receipt next 15 days for all the receipts Quality check not required. After this 15 days of SKIP next 15 days quality check required. This cycle should go on. Is this can be done through DMR ???. can somebody guide me how it can be achieved in standard or we need to go to any enhancement.

Thanks

Kumar
