Property |
Description |
|
Rules |
If this switch is activated, the decision table is executed in the rule processing. |
|
Always allowed |
The switch is only available if the Rules switch is activated. The Always Allowed switch determines that the decision table is always running, and prohibition rules can be created that prevent execution. Conversely, permission rules can be formulated that allow execution if this switch is switched off. The creation of permission rules makes no sense if the always allowed switch is set. |

Fields for inbound columns
Field contents in input columns are checked using the key term Is.
Examples:
Is = "RAL1001"
Is IsA ::[Sigma 75]
Is >= 10 And Is <= 100
Is > Price
Fields in output columns
Field contents in output columns are interpretable expressions, as they are also used in function programming. For example, strings with the double or single commas must be framed and decimal numbers shall be specified with the decimal point (.) without exception.
Unbound decision tables
If a decision table is created without missing control variables, it can only be checked with the CheckByParam or CheckByInValues attribute functions of the decision table.
