Sampling Drawing Procedure

Hi Experts,
Can anybody please explain me in short,
Primary sample
Pooled sample
Reserve sample
Edited by: Raja S on Jan 29, 2009 7:23 AM

Dear Raja
Primary samples
Physical samples drawn directly from a material or batch that will be inspected or used to create pooled samples.
pooled samples
Physical samples to be created by mixing the contents of two or more primary samples from the same material or batch.
Reserved Samples
Primary physical samples drawn from a material or batch reserved for future inspection.
In each sample-drawing item, you must specify how many primary, pooled, and reserve samples should be created. For primary and pooled samples, you can:
Specify a fixed number of physical samples.
Allow the system to determine the number of physical samples automatically on the basis of a sampling scheme.
You can specify only a fixed number of reserve samples.
For primary and pooled samples, you can also enter a factor that instructs the system to create a greater quantity of physical samples than you need for the current inspection. For example, if you specify a factor of "3," the system creates sufficient quantities of physical samples for you to carry out three inspections.
Hope this helps

Fetching the latest drawing No. after changing Sampling Drawing Procedure

Hi QM Masters,
I have 1 Report in that I fetch Drawing No. against Inspection Lot.
When I create a Inspection Lot at that time Drawing No. will generated in the system. Sampling Drawing procedure is assigned to the Lot. But the problem is that When I change the sampling procedure New Drawing No. is generated against the same lot.
Both Drawing No. are updated in QPRS table against the same lot. That's why It is difficult to fetch the latest Drawing no.
How I fetch the latest drawing no. after changing the SDP?
Gives me the Expert logic to fetch the data.

Hi can you check the fields ENTDATUM and ENTZEIT for sample drawing date and time or this date is different for you in the same table QPRS

Difference between Sampling Procedure and Sample-drawing procedure

Friends,
I am new to QM and started learning QM Module. My doubt is what is the difference between Sampling Procedure and Sample-drawing procedure?
The reason for my doubt is, we can determine the sample quantity with Sampling procedure itself. then what is the need of sample-drawing procedure?
Also describe primary, pooled and reserved samples.

IMIMINT

Hi,
Sampling Procedure
Definition
A procedure that contains the rules for determining the sample size for an inspection. The sampling procedure also specifies the type of valuation to use for results recording (attributive, variable, or manual).
Use
You assign a sampling procedure to each characteristic in an inspection plan to calculate the sample size.
Sample-Drawing Procedure
Definition
A master data object in which you plan the drawing of physical samples. In the sample-drawing procedure, you specify:
Which categories of physical samples must be drawn
How many physical samples must drawn
The size of each physical sample
Whether the drawing of physical samples must be confirmed
Use
The system uses the information in the sample-drawing procedure together with the information in the inspection plan to calculate the physical sample sizes, and to create physical-sample records when an inspection lot is created.
Primary Sample : It is the sample drawn from the lot directly.
Pooled Sample : It is the sample whcih is combination of 2 or more primary samples.i.e. primary sample sfrom say 3 differetn drums is mixed and tested.
Reserved Sample :sample which is preserved for the testing in future.
or in other words
Primary samples (1st stage)
Physical samples drawn directly from a material or batch that will be inspected or used to create pooled samples.
Pooled samples (2nd stage)
Physical samples to be created by mixing the contents of two or more primary samples from the same material or batch.
Reserve samples
Primary physical samples drawn from a material or batch reserved for future inspection.

Sample Drawing Procedure & Sampling Procedure

Dear All,
I am little confused between Sample Drawing Procedure and Sampling Procedure
1) During Sample Size Calculation what's the roll of both Object?Is there any relation between this two object?
2)And During Automatic Creation of quality lot on which factor Lot size is depend Particular in Stability Study

Quality management( difference between sampling procedure & sample drawing)

Hi Experts,
I am very new to quality management module & working in united states. i am trying to find difference between sampling procedure & sample drawing procedure.
I see that sample drawing procedure is assigned to Inspection Plan & sampling procedure is assigned to characteristics, But i don't know the difference between these two, Please help me.
Regards,
Seshu

Hi,
SAMPLING PROCEDURE :
A procedure that contains the rules for determining the sample size for an inspection. The sampling procedure also specifies the type of valuation to use for results recording (attributive, variable, or manual).
Use
You assign a sampling procedure to each characteristic in an inspection plan to calculate the sample size.
Integration
In a sampling procedure, you must activate the function for inspection points based on a sample-drawing procedure if you assigned a sampling procedure and a sample-drawing procedure to an inspection plan at the characteristic and header levels respectively.
SAMPLE DRAWING PROCEDURE:
Definition
A master data object in which you plan the drawing of physical samples. In the sample-drawing procedure, you specify:
Which categories of physical samples must be drawn
How many physical samples must drawn
The size of each physical sample
Whether the drawing of physical samples must be confirmed
Use
The system uses the information in the sample-drawing procedure together with the information in the inspection plan to calculate the physical sample sizes, and to create physical-sample records when an inspection lot is created.
Structure
A sample-drawing procedure contains the following types of information:
Header data
The sample drawing header contains the following information fields and control indicators:
Key that identifies the sample-drawing procedure
Short text description for the sample-drawing procedure
Authorization group that limits the access to the sample-drawing procedure
Text for matchcode searches
Long text indicator
Indicator for calculating the number of physical samples on the basis of number of containers in the inspection lot (as opposed to the base unit of measure)
Confirmation indicator to activate or deactivate the confirmation requirement
Lock indicator to prevent the sample-drawing procedure from being used
Usage indicator that shows whether the sample-drawing procedure is currently used in an inspection plan
Sample-drawing item(s)
A sample-drawing item contains specific instructions for creating physical samples with respect to a specific inspection lot container type and specific partial-sample numbers in the inspection plan. In a sample-drawing item, you can also specify:
Which categories of physical samples you want to create (primary samples, pooled samples, and reserve samples)
The physical sample container you use to draw each category of physical sample
A factor to increase the quantity of physical samples to be created (for example, if you need to carry out more than one inspection)
The number of physical samples to be created (fixed number or variable number based on a sampling scheme)
Integration
The sample-drawing procedure interacts with the following planning objects:
Inspection plan
You assign a sample-drawing procedure to an inspection plan to activate the functions for sample management.
Sampling scheme (optional)
If you want the system to determine the number of physical samples automatically on the basis of a sampling scheme, you can reference sampling schemes in a sample-drawing procedure.
Hope it helps...

Physical sample and physical sample drawing relationship

Dear all,
When an inspection lot is created in a inspection plan using sample drawing procedure to determine physical sample size, the following two objects created automatically.
Physical Sample Drawing Number
Physical Sample Number
The relationship between these two objects is... one physical sample drawing number can represent more than one physical sample record, am I correct?
Thanks
Karen

Physical Sample Drawing Number : it represents unique number for physical sample
Ex. if you sampled 100 pcs SAP gives Numbe Number for this 100. pcs
Physical Sample Number it gives the number for bifurgation of this qty.
Ex. out of 100 pcs 20 is physical sample 20 for pooled and remaining is reserve etc.
Cheers,

Make Draw Procedure and Sampling Procedure Quantities Match?

I need to set up an inspection plan where one item is taken from each container and combined into 1 pooled sample. The items in the containers are in eaches and the number may vary from container to container. Think 5 buckets filled with pebbles. I want to end up with a pooled sample that is a total quantity of 5, total containers to sample is 5 and sample size per container is 1.
On my inspection plan, my Sampling Procedure is set for a fixed sample size of 1.
The number of buckets may vary from shipment to shipment, so my Draw Procedure is set to have the number of primary samples be P2. However, when I set the number of pooled samples to 1, I end up with sampling instructions that say to take 0.2 pebbles from each of 5 buckets.
I can set up the Draw Procedure to only have Primary Samples and my sampling instructions will show 5 primary samples but it will not indicate that they should be taken 1 per container.
Setting my fixed sample size to 5 solves this particular problem but as my material may arrive in 6 containers next time, it is not a long term solution.
It seems to me that I need to be able to set my sample size to also vary based on the number of containers. I can't do that using a pebble to bucket conversion, as this is not a constant number. Ideally I would like a Sampling Procedure with a sample size of P2.
Is there a way to create a Sampling Procedure that varies based on the number of containers received? Or is there another option?
Thanks,
Deb

You can achieve this by using Sampling Determination "300-Sample schema" If require modify Function Module "QDRS_SAMPLING_PLAN_SAMPLE"
Thanx!!

Confirm Physical-Sample Drawing

Hello,
Are there any other way to release a physical-sample drawing other than QPR4? I'm trying to release a physical sample however I encounter this error "Physical-sample drawing ###### was not confirmed. Call the program "Process physical-sample drawing" and confirm the physical-sample drawing ########."
QPR4 is fine when releasing it manually, but what I'm trying to do is having it in BDC, and since QPR4 is in ALV format it is not supported in BDC. That's why I'm looking for an alternative way to confirm the drawing.
Thanks in advance
uniox

Hi
Use SHDB & copy this code & call this button in BDC
This will work in Mass

You can use QPRS table.
if you want T code then create Querry using SQVI make a T code

Sampling procedure-Square root n+1

Hi All,
I need to calculate the sample size based on the Containers & Square root n+1.
How to configure the system & how to maintain the master data to get the sample size.
User also insisted only the sample size has to be calculated, but he will enter only one composite result entry
Regards
Subbu

Hi Subbu,
you can use Physical Sample to control the sample Size.
You must to define a Sample Drawing Procedure (QPV2) as relevant for Container Number, then assign the formula 'Square Root n1´ ( TRUNC(SQRT(P2)1) ) in the partial sample. In this scenario, I suggest you to configure the "Container number' as a mandatory field during the goods receipt once the system will need this information to calculate the sample. For a single result recording, you can define a pooled sample.
I hope it can help you.
Best regards,
Robson

Sample Management during goods receipt

Hello All,
I have a scenario where a goods receipt inspection is active for material X. Inspection type 01 can be activated and material goes to inspection stock.
But instead of moving all the quantity can i move sample from the quantity..?
Ex: good receipt- X material 100 kg and i want only 30 gm to come to inspection stock for quality check (to avoid blockage of 100 kg)
I have maintained inspection type 15 for material X, but how to calculate 30 gm sample..?
Please help me

Result recording & display of multiple tests/analysis of single sample

Hello Friends
Here is my scenario;
I receive 500 kgs of material in 5 bags. I want to draw sample of 1 kg from each bag. Thus I will be having 5 samples. I will perform the required tests on each sample. For testing I am consuming @250 gms of material. Out of 5 samples, I had to conduct the retest on 2 samples. I want to do the result recording of these tests/samples. In my understanding there will be 7 result recordings which will include 2 of Retest of 2 samples. I would like to display all the values recorded ( atleast for each samples ). Also, I would like to see the individual values and not the averaged out values the recordings.
How can I take care of constraints due to pooled sample i.e. it allows only the result recording of pooled sample and not the subsequent samples.
I would appreciate your detailed guidance on this issue.
Regards
mahesh

Hello Lenin
Normally, we use Sampling procedure with Fixed Sample as Sampling Type withAttributive inspection non confirming units as valuation mode. Determination Rule as 10 ( Fixed Sample ). Sample drawing Procedure followed is "draw from all containers". Irrespective of our present settings, I would appreciate if you let me know the settings to be made in order to map given scenario.
