Locking table properties

About this task

Decision tables have locking facilities that allow you to protect your decision tables against editing by others. The locking rules should be specified in the context of a template library to be applied on instances of this decision table. For both condition columns and action columns, you can lock the structure, data, or both.

To define decision table locking requirements:

1. Right-click any column header in your decision table, and then click Table properties. The Table properties editor opens.
2. Choose which locks you want to apply:

   Enforce locking rules on this table

   The default is off to allow you to edit your decision table and lock rules. Set to on for decision tables used in a package on which you want to enforce locking rules.

   Show lock icon in columns

   If on, the Lock icon is displayed on any locked condition and action items.

   Prevent addition or removal of columns

   Prevents condition or action columns from being added or deleted.

3. In the Condition columns section, select any of the following locks:

   Lock test

   The test expression associated with the condition column cannot be changed. Note that cell content, including cell-specific test operators, can still be changed.

   Lock partitions

   Partition items cannot be added to or removed from the selected condition column. The values of existing partition items can still be changed, but no rows can be added to or removed from this column.

   Locking partitions locks partitions in all preceding columns because adding a new partition item to a previous column can create a new row in the locked column.

   Lock values

   The values of existing partition items or the cell operator cannot be changed.

4. In the Action columns section, select any of the following locks:

   Lock action

   The expression associated with the column cannot be changed.

   Lock status

   The status of the action cell cannot be changed. The action status specifies whether an action is enabled or disabled. See Table cells for details on disabling action columns.

   Lock values

   The values in the action cell of the selected column cannot be changed.

5. Click OK to apply your selections.
