Removing Operations in the Source View


Some operations on your data can be removed in the source view. For example, if a previously added transformation is no longer applicable, you can remove it. Or, if you have deleted rows or columns from the analysis and you want to bring the missing data back, you can remove the delete-operation.

  1. In the Data panel, make sure the data table with the operation of interest is selected.

  2. Comment: This step is only applicable if you have two or more data tables in the analysis. If this is the case, select the data table of interest from the drop-down list at the top of the Data panel, otherwise, go to step 2.

  3. Click on the Expand data panel for tools and details button, data_expand_data_panel_for_tools_and_details_i.png.

  4. In the expanded data panel, click Source view.

  5. Comment: You may need to first click the Go to data table view link to be able to see the Source view button.

  6. In the Source view, click on the node where the transformation or operation you want to remove was applied.

  7. Comment: If there is an error in a transformation you will be guided to the affected node and transformation group by red error icons. Transformations may have been added on a data loading-step, as well as on a later step.

    Response: Details about the selected node are shown in the bottom left part of the source view.

  8. For the operation you want to remove, click on data_delete_i.png.

Tip: If you have added multiple transformations in one step (within the same transformation group), and you only want to remove one of them, click on the settings icon instead, data_settings_i.png. In the Edit Transformations dialog you can both remove single transformations and insert new transformations to the group.

Example: Removing a 'replace value'-operation that is no longer applicable

In this example, the creator of the analysis used the 'replace value'-transformation to fix a spelling error in the data table. However, at a later stage, someone updated the data in the linked source and the 'replace value'-operation was no longer needed:

data_replace_value_operation_with_issues.png

There is an information icon on the node, as well as on the 'replace value'-operation in the step list. A tooltip gives you information about the issue:

Click on data_delete_i.png to remove the operation.
