Decision Logic Page Actions
Decision Logic Transform/Delete
The Transform action converts any entered logic to a different boxed expression type. The list of available target types depends on the original boxed expression type.
The Delete option of the Delete action clears all entered decision logic, including the selected boxed expression type. The Clear option erases all entered decision logic but retains the original boxed expression type.
Cell Duplicate Row/Copy/Insert/Delete
These actions operate on selected rules or input and output columns of a decision table.
Decision Table Merge
These actions operate on a decision table or selected columns or cells of a decision table. Merge Similar Cells will merge vertically adjacent input entries if they have the same decision logic. Unmerge All unmerges all input entries in the decision table.
Technically, a merged cell should not have unmerged cells to its left. To implement this constraint, first Unmerge All, then select cells to merge and click the popup Merge action.
View Standard/Edit/Filter
The Stadard view displays the boxed expression strictly as pictured in the DMN spec. In this view the logic is not editable.
The Edit view includes a few additional features in the display, and the logic is editable. Normally you will work in the Edit view.
Filter displays only rules in a decision table containing names or values specified in the filter.
