The following value input types can be selected in value definition. Depending on the selection, various settings can be made.

free value quantity (numeric)

If a free value quantity is of the type numerical, a minimum and maximum value has to be entered for the code part. If minimum and maximum value are empty, any value can be entered.

Admin_Kodierungsschema_freie_Wertemenge_1

Value definition means: Number between 1 and 22 (each including)

free value quantity (alphanumeric)

If a free value quantity is of the type alphanumeric, numbers and letters can be entered as code part. If the value definition is empty, all alphanumeric characters can be used.

The following special characters in connection with one or several alphanumeric characters limit the code assignment (the code part contains in all examples two positions):

Character	Meaning / Example
[]	Areas of alphanumeric characters [A-C][D-F] - the first position of the code can contain the characters A, B, C, and the 2nd position the characters D, E, F.
.	Any character .A - the first character is optional, and the 2nd must be an A.
$	End character A$ - the last character must be an A, the $ sign must come after the A.
^	Start character ^A - the first character must be an A, the ^ character must come before the A.
*	Any number of characters G* - any number of Gs can be contained in the code part. It is allowed to assign no Gs.
+	Any number of characters G+ - any number of Gs can be contained in the code part. At least one G must be assigned.
[^]	Not allowed sign [^A] - an A must not be entered at this position.

These expressions can be combined with each other in any way.

fixed value input

All values valid for a code part are entered with a description.

Please note:

If the wildcard character * is used as value, any characters can be used on the position of the wildcard character.

Multi-digit value sets:

For multi-digit value sets, for example, 3 digits, either all three values can be defined or only individual positions. The other positions are automatically filled with fill characters. Fill characters can also be entered directly when creating the value definition. The individual values of the value definition must be unique.

Example of value definition with fill characters where values are not unique

Fill character

Only fill characters may be entered into the corresponding code positions. A fill character must not be empty. If the fill character is deleted and saved afterwards, the saving is rejected and the box for the fill character is displayed with a red border.

Number range (sequential)

For the defined part of a code a sequential number is generated by the system. The administrator can define the number with which the next element is created and the step size between the numbers.

Possible settings for the number cycle

Please note:

•Minimum value default = 1; empty or < 0 not allowed

•Maximum value default corresponds to the number of possible positions and the maximum value; empty is not allowed. --> So 999 means that the number cycle can have a maximum of 3 positions, with 999 as the largest possible number.

•In the case of a multi-digit number cycle (e.g. 999), the first positions are filled with the fill character as long as they are not used (e.g. ..6).

Admin_Kodierungsschema_Nummernkreis_Anwendung

Number range (code-specific)

For the defined code part, a sequential number is generated by the system depending on the previous code. The administrator can define the step size between the numbers.
