My Requirement is to get samples with formula , i have to draw the samples as per formula.SO i am using sample drawing procedure with formula and i am writing formula there.But i want to use dynamic modification rule.Beacuse req is to change sampling on each 7th supply, so on each 7th supply sampling is 100% and for next 7 supply sampling is Sq.root(n)+1.So for meeting this thing i want use DMR, but i can use DMR with sampling procedure which are having sampling scheme with severity, so within severity we can change our scheme.

1. When we are procuring material, material is comming in containers. Suppose if material is comming in 10 containers may be i have to take samples from 4 containers and from each contaner ,i want to take 20 ml.

2. Now when its is first time supply from any vendor, we are taking 100% samples, like if 10 Dr GR than sample from all 10 DR need to be taken.

3. From second supply to next 7 supply, sample size is Sq.root (N)+1, so it will be 4. Than on 8th supply it should again be 100%
