Use of Additive sample in Results recording in QE01 t code

[Former Member]

Dear All,

While creating MIC I selected additive sample and destructive sample where required and saved the same. While recording results against the MIC for which destructive sample is selected, I could see in QA32 t.code that, the qty is getting displayed in sample usage field. But for additive sample I could not see the behavior either in QE01 while recording results or in QA32 while making UD. Kindly let me know how to see the results if additive sample is selected for an MIC. Expecting results at the earliest.

If any further clarification is required, please do revert back to me.

Dear Nitin,

Thanks for your prompt reply. Please clarify me on the below mentioned points for better understanding.

1. As per your reply what I understood is, if additive sample is selected the sample size would be zero. Then what is the purpose of selecting additive sample? - pls explain.

2. If sample size becomes zero, then how will I record results for the additional qty for which QC has been carried out. Is there any provision for it?

3. As far as destructive sample is concerned I am clear with it.

Additive samples SHOULD increase the overall calculated sample size.  It should have no impact on inspection lot quantity.

This can be used when tests are split among labs.  Maybe an ID or wet chemistry lab and maybe an application testing lab.  Also, maybe some tests are done in house while other tests are done by an outside lab. 

MIC 1 sample size 2 Lab 1  Destructive     +2

MIC 2 sample size 4 Lab 1  Additive          +4

MIC 3 sample size 4 Lab 2  Additive          +4

MIC 4 sample size 1 Lab 2                         +1

MIC 5 sample size 1 Lab 2                          -  (uses same sample as MIC 4

MIC 6 sample size 1 Lab 2                          -  (uses same sample as MIC 4&5

MIC 7 sample size 2 Lab 3 Destructive      +2

Lab 1 gets 6 samples

Lab 2 gets 5 samples

Lab 3 gets 2 samples

Total samples required: 13

Samples destroyed: 4

Quantity that can be posted to unrestricted, retained or whatever: 9

Hi Srinivasa,

You can use F1 help for detailed description about the additive sample. It has been explained nicely.

Hope it helps.

Thanks for your reply.

Using F1 help learnt how additive sample and destructive sample works and was able to see how destructive sample works.

But I want to see how additive sample works either while recording results or while making UD in QA32.

Ok. I'll share what I know,

Case 1: All MICs are additive:

Say you inspection lot qty is 20 units, then sample size would be ZERO. System does not calculate the sample size as I considers the sample qty. as an addition to insp lot qty.

Case 2: Mixed MICs, fewer additive and other normal (No indicator is set for add or dest)

Say you inspection lot qty is 20 units, then sample size would be calculated based on the other MICs for which no indicator is set in accordance with Sample type defined in the sampling procedure.

Case 3:  Mixed MICs, fewer additive and other Destructive

Say you inspection lot qty is 20 units, then sample size would be ZERO and 'to sample usage' would based on destructive MICs.

So basically, system calculates the sample size based on these indicators. If additive then it is ZERO, if destructive then it would propose it to sample usage.

I hope that would give some idea about its usage. Rest you can explore by running few test cases by changing the indicators in different intervals.

Hi Srinivasa,

I'm afraid I cannot help you much on this topic as we don't use this feature. I explained only those things which I had observed during testing phase in the project. Thought to share so that you can run your own scenarios and understand it better

Basically, what we did do and understood that

1. You dispose the sample qty (destructive) from the total inspection lot and same gets reduced from the stock also.

2.But in other way, if you use additive, your lot qty remains unchanged even after using the sample qty for testing/analysis etc

It is like measuring hardness value of a steel plate by using a certain qty/area, still you do not dispose that part as it is a non destructive testing.  But if you need to do chemical analysis then you cannot take whole plate to lab. Instead you take out a sample which results in reduction of plate qty, as it is destructive testing. 

I'm also following this thread for an perfect explanation from other QM experts.
