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.
