Hi,
Let me try to explain the DMR in short.
Let us suppose for example, we have set Sampling procedure to pick 50% of the Inspection Lot and do UD based on the RR.
Now consider following cases:
For 1st time GR --> We inspected 50% of the Lot and it is cleared as good Quality
For 2nd time GR --> We inspected 50% of the Lot and it is cleared as good Quality
For 3rd time GR --> We inspected 50% of the Lot and it is cleared as good Quality
For 4th time GR --> We inspected 50% of the Lot and it is cleared as good Quality
For 5th time GR --> We inspected 50% of the Lot and it is cleared as good Quality
... so on and so far.
This is a case with no DMR.
As inspection Process is a cost for the company; there is a arguement in favour of skipping Inspection process for the 6th time as the earlier history is good. It can be safely assumed (based on the earlier pattern) that even if we do GR for 6th time,it will pass as Quality Inspection. Dynamic Modification tries and maps this situation in SAP.
The earlier scenario will now look like below with DMR (which tries to vary Inspection Scope based on UD):
Stage 1: For 1st time GR --> We will inspect 50% of the Lot --> We will call it Normal Inspection
Stage 2: For 2nd time GR --> We will inspect 20% of the Lot if UD for stage 1 is Okay --> We will call it Reduced Inspection
Stage 3: For 3rd time GR --> We will inspect  0% of the Lot if UD for stage 1 & 2 is Okay --> We will call it Skip Inspection
Stage 4: We will inspect 100% of the Lot if any point the UD is rejected for the lot --> We will it Tightened Inspection
These Inspection Stages are defined in the DM Rule.Normal,Skip,Reduced and Tightened is called the Inspection Severity.
Other Important Points
1. The DMR can be applied for Plant, Material and Vendor Combinations and is called Dynamic Modification Criteria.
2. The Dynamic Modification, Stage Changes can happen while UD or while Lot Creation. We need to define this in the Inspection Plan Header.
3. DMR is often used in sync with Sampling Scheme to change Inspection Lot quantity based on the Inspection Severity
4. There are further finer points wrt DMR that will only become clear once you start using it.
Please let me know if this sounds Okay.
Thanks,
RKM.
