Setup Skip Lot Purchasing Control Plan question

Hello all, 

I’ve been testing the Skip Lot on Purchasing Control Plans, and it does appear to be working, but the help is unclear about how some of the setup is applied and what the registration of some results means. I have entered three Purchase Orders of 100 each and I’m attempting to test the Attribute Skip Lot. I believe I have it setup as I’ve been attempting to enter nonconformitites and the sample qty has gone from 13 to 20 on the third PO. However, I’m unsure on the analysis result what the two mandatory fields are actually asking for. The help isn’t clear. 

I have the following acceptance sampling setup on the Purch Control Plan and Trigger:

On the SFPP, I have not configured anything for Inspection Info, I’m assuming this is not needed:

Any guidance on if my current setup is correct, or the proper way to interpret the Skip Lot setup would be greatly appreciated.

I you have found a total of 10 scratches on 3 items, then “No of Nonconformities” = 10 and “No of Nonconforming” = 3.

The Attribute Acceptance Sampling logic (according to ISO 2859-3) only consider the “No of Nonconforming” value. The inspected items are either “Ok” or “Not OK”.

I recommend you use categorical instead of attribute data points when using attribute acceptance sampling, since it simplifies the reporting of inspection results.

You could use a Category Data Type looking something like this, where the inspected items either Pass or Fail the inspection:

 

If you want more information about Acceptance Sampling in general, I recommend you look at the Topic description in the Online documentation:

      Thank you very much for the clarification, ​@Peter Lundgren! I was not aware that Category could be used (I only saw Variable and Attribute). I currently have the Pass Fail already setup, so I will test using your recommendations.
