Generate Physical samples during goods receipt, sample size should be ML while insp lot in Liters.


I am new to QM, my requirement is to configure the below scenario,

The Raw material comes in a tanker with compartments, the number of compartments can vary from 1 to 6.

The sample size must be 200 ML, while the Inspection lot is maintained in Liters.

So, if a tanker comes in with 4 compartments, then it should create 4 Physical samples with 200 ML each.

The GR should be done for the entire inspection lot minus the Physical samples.

I have maintained the below settings, with some Basic QM knowledge, i might be completely wrong with the below approach, because i still feel this is not the correct configuration settings for the above scenario.

Please advice.

1. Settings in Sample drawing procedure - "COMPART"

Under Primary Samples tab

lot container - ML

ToPartSampleNo - 200 (for sample size)

Size factor 1

Under Number of Physical samples:-

Fixed number 6

2. I have maintained a sampling procedure with sampling type "fixed" and inspection points as "Sample management". The sample size in 200 ML.

3. Settings in Inspection plan

Insp Points - "130" (Inspection point based on container)

Sample-drawing procedure - COMPART

4. Settings in MIC:-

I have maintained in control indicators as destructive sample, to post in sample stock.

After maintaining the above settings, i am not getting the desired sample for the inspection lot.

    I've dealt with this issue many times in the past at many different clients. I encourage you to simplify, simplify, simplify.

    No one is tracking the quantity of 200 ml samples out of the tanker. 800 ml isn't even enough to barely register on a truck scale. If the driver went to the bathroom or drank a coffee you'll already be off by the equivalent weight of the sample. :-) If you record offloaded quantities by a pump meter, you'll lose 800 ml in the hose when disconnecting or flushing. And the samples usually have to be taken and approved before off loading anyway so they probably wouldn't be record anyway via the meter or would be included in the flush.

    Make your physical samples based on container and with a container type of EA. Define the PhysSampContPrimStg as a 200 ml bottle so you have some reference to sample size if you want. Or put the sample size into the sampling text instructions if you print them

    On receipt they enter 4 containers received with a UOM of EA. This creates 4 physical primary samples. If only 3 compartments they enter 3 containers, 2 compartments they enter 2 containers, etc. etc.. Then you can create a pooled sample and reserve samples if you want.

    This avoids having to inventory and post the small sample qty's as in most tanker deliveries, these are inconsequential since these are either drummed off or dumped into a larger holding tank, often mixed with an existing heel in the tank as well. Which in any large tank, rarely has the accuracy to a ml level.
