Master data record that regulates how samples are taken and formed.
You enter the following data in the sample-drawing procedure:
You define the type of sample drawing. That is, you choose one of the following options:
The samples are taken at predefined time intervals, for example, every five hours.
The samples are taken at predefined quantity intervals, for example, every 500 kg.
The samples are taken on a per container basis, for example, one sample for each pallet.
The samples are taken in accordance with the specifications that you defined in Customizing for the Quality Inspection Engine in the Business Add-In (BAdI) QIE Sample Calculation.
You define the sample-drawing units.
You define the sample-drawing instructions for the sample-drawing units.
The sample-drawing procedure is a collection of sample-drawing units. The sample-drawing procedure itself does not contain any data for the sample drawing. You can define any number of sample-drawing units for a sample-drawing procedure. For every sample-drawing unit you can specify sample-drawing instructions for the following sample categories:
Primary sample
Pooled sample
Reserve sample
Note the following:
For reserve samples, you may only specify a maximum of one sample-drawing instruction.
If you specify more than one sample-drawing instruction for primary samples, you may not specify any sample-drawing instructions for pooled samples.
If you specify one or more sample-drawing instructions for pooled samples, you must specify exactly one sample-drawing instruction for primary samples. This sample-drawing instruction defines the primary samples that are mixed together to form the pooles samples.
You can specify the following sample-drawing instructions for one sample-drawing unit:
Primary sample |
Pooled sample |
Reserve sample |
---|---|---|

Note the following for the sample quantity that you specify in the sample-drawing instructions:
You must either specify the sample quantity for none or for all of the sample drawing instructions for a sample-drawing unit.
If you specify more than one sample-drawing instruction for pooled samples or primary samples, all of these sample-drawing instructions must contain a sample quantity and these sample quantities must have the same unit.
If you specify sample-drawing instructions that do not adhere to these specifications, the system ignores these sample-drawing instructions and creates a primary sample that includes the whole sample quantity when the sample calculation for the inspection document is executed.
If, when the system creates the inspection document based on the inspection rule, the system finds a sample-drawing procedure as well as a sampling procedure, it will initially only take the sample-drawing procedure into consideration. Only if the system cannot find all the data it requires in the sample-drawing procedure, will it take the sampling procedure into consideration.
