Processing of Characteristics
In connection with the EH&S-QM interface, it is important that you distinguish between class characteristics in
specification management
and inspection characteristics in the SAP
Quality Management
(QM) component:
Class characteristics
Characteristic from the classification system that is entered in the value assignment type for a specification and determines the different properties of a specification.
Values for these characteristics can either be numerical (for example,
1,3
) or a text (for example,red
). Inspecification management
these texts, or qualitative characteristics, are identified in a value assignment type (for example,Color
) by phrases (see Phrase Management ).Inspection characteristics
Characteristic on the basis of which a quality inspection is performed. As for the class characteristics there are two types of characteristics:
Quantitative inspection characteristics
Numerical characteristics (for example,
1,3
)The system takes the contents of this type directly from
specification management
when it creates an inspection plan, without any conversion being necessary.Qualitative inspection characteristics
Nonnumerical characteristics (for example,
red
)These texts are identified in
Quality Management
by codes as opposed to the phrases inspecification management
.
From the contents of the class characteristics entered in a value assignment type, the EH&S-QM interface creates inspection characteristics in the inspection plans when it creates the inspection plans. Quality inspections can then be executed as usual in
Quality Management
using these inspection characteristics.

Converting Phrases to Codes
For qualitative values, the interface converts the phrases and phrase groups entered for the value assignment type into codes or code groups that can be used by
Quality Management
. These codes are stored in selected sets that are also created by the interface. This means the characteristic values of a value assignment type are grouped together in a selected set.
When it creates an inspection plan, the system checks to see whether a code was already created from a specific phrase in the past:
If it was, this code is used in future for the relevant phrase.
If it was not, a new code is created for the relevant phrase and used in future.
The codes that already exist in
Quality Management
are not used. The system creates its own new codes that are created once by the interface when inspection plans are created and always used in future for the same phrases (for information on setting up the respective number ranges, see
Basic Settings
).
Note
Qualitative inspection characteristics in
Quality Management
can have a positive or negative attribute. The class characteristics cover only positive attributes. For this reason, the interface transfers a not-OK code as standard to all selected sets it creates as negative attributes (see environment parameters under
Basic Settings
).
Use of Master Inspection Characteristics
You can use data from master inspection characteristics when you create inspection plans. Master inspection characteristics are inspection characteristics that are intended for frequent use in inspection plans or for evaluation across several inspection plans. They make inspection planning easier and more standardized.
You have the following advantages if you use master inspection characteristics when you create specification-relevant inspection plans:
Where-used list
Multilingual capability
Reference to batches

Quality Management
component.
