Automatic rule addition

If a deci­sion ta­ble is incomplete, but otherwise error-free, the user can decide whether or not the mis­sing rules should be added automatically.

The function of adding mis­sing rules is e­xe­cu­ted step by step, i.e. even if there are several mis­sing rules, LF ET always adds only one mis­sing rule and adds the next one only if the previously added rule had been checked and edited by the user.

Only if the condition is correct, i.e. the rules already existing are logically correct and calculable, the rule addition icon in the icon bar is active.

Executing rule addition

  1. Click Add mis­sing rules 01 (left) or 02 (right) in the icon bar:

    • the missing rule is calculated and inserted in the deci­sion ta­ble

    • the cursor is placed in the new rule.

  2. Check the logical relationships in combination with the new rule, for example, whether changes are made to conditions and actions.

  3. If necessary, edit these changes in the conditions and actions.

  4. Repeat steps 1 to 3 until no more rules are missing.
