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.
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).
You assign a sampling procedure to each characteristic in an inspection plan to calculate the sample size.
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:
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
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.
A sample-drawing procedure contains the following types of information:
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
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)
The sample-drawing procedure interacts with the following planning objects:
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...
AWARD IF HELPFULL
thanks for ur quick reply Priyanka. I got better idea from ur answer. Still i have some questions regarding this
From ur answer i understood following points.
1) sample procedure is used to sample size for inspection
2) sample drawing procedure is used to calculate sample size for PHYSICAL SAMPLES(not for normal inspections).
& i have following questions
1) Is there any link between sample procedure & sample drawing procedure?
2) what is the use of assigning inspection points?
