Tracking operations in the History tab

The History tab in the Data Manager and the Rule Manager display all the operations performed by the user during the current session.

Every time the Save button is clicked, each operation performed since the last save operation is displayed in a new row. History operations are irreversible, i.e. the undo command does not have any effect, but operations can be deleted, moved or copied and pasted between Data Managers.

The save command is basically used to transfer operations from WYSIWYG interface to the history.

Each series of operations are identified by an icon according to the type of operation performed.

The status of each task is also displayed in the Status column:

  • Ready status: operations are not made permanent until the task is computed, and consequently they are displayed with a blue "ready" icon. If the task is subsequently closed and reopened in ready status, the non-computed operation will still be in the History tab, but the data displayed will correspond to the data before the operation. If you then perform new operations on the same data, these operations will overwrite those in the History tab that have not been computed. For example, if you perform a filter on column x and then save and close the task, when you re-open the task the data displayed will not be filtered, although the filter operation will be listed in the History tab in ready status. If you now perform new operations, for example a new filter, these will be performed on the original data, effectively overwriting the previous operations in the History tab. Consequently, it is advisable to compute the Data Manager before performing new operations, and ensure all operations in the History tab are green (computed).

  • Computed status: once the task has been computed, the status icon becomes green and the Undo command is disabled.

Possible operations

You can perform the following operations in the History tab:

 

Operation

Procedure

View and copy the Rulex Language (RL) code

Rulex Language (RL) is a programming language used to manage many of the operations performed in the Rulex GUI. 

  1. Double-click on any cell in the Action column, the RL code associated to the operation is displayed. 

  2. Right-click on the cell in and select Copy action code to clipboard to copy and paste the code to another editor.

Legend

  • Rows starting with “//” are comments and consequently do not correspond to processed RL statements. 

  • @set is a variable containing the dataset and includes: 

    • @set.att  for the attribute properties 

    • @set.data for the data matrix 

    • @set.rec for the record properties.

Copy and paste actions

Copying and pasting allows you to copy single operations performed in one Data Manager to another.

  1. Right-click the cells of all the operations you want to copy in the Action column.

  2. Select Copy actions.

  3. Right-click again on any cell in the Action column and select Paste actions: the operations will be added to the end of the list.

Alternatively the CTRL+C / CTRL+V key combinations can be used to copy and paste actions.

Delete selected or all operations

  1. Select one or more cells in the Action column.

  2. Right-click and select either:

    • Delete actions, to remove the actions in the History table.

Alternatively the Delete key can be used to delete actions.

Cut operations

  1. Right-click on any cell in the Action column.

  2. Select Reset actions to reset all the operations to the Ready status.

As the history is normally recomputed from the first non-computed row, resetting operations allows you to re-compute all operations from the first row. This is particularly useful when errors occur, or if you have changed a process variable value and want the Data Manager to be re-computed with new value.

Compute up to here

This option allows you to compute the operations performed up to the chosen point.

  1. Right click on the operation you want to set the computation’s end point.

  2. Select Compute up to here to compute the selected operations.

Drag and drop operations

You can move the operations to a different position in the history to change the order in which operations are performed.
