Editing column matching or other settings for added rows
If you have added rows from a different source to a data table, there may be occasions when you must update the settings used for matching the data from different sources together. For example, a column used for matching linked data may have been renamed or removed in either of the sources.
On the authoring bar, click
Make sure the data table of interest is selected in the upper-left drop-down list.
- In the Data canvas, click the settings button on the Added rows node.
Settings for added rows dialog, verify that the column matching is still valid, or edit the matching as desired. This is done by adding or removing matches.
Click on the plus sign and select a column from the list to add a match for one of the columns from the original data. Click on the x on a row to remove a match. If an earlier match is broken, click on the exclamation mark and select a new match, when possible, or remove the match.
- Optionally, if there are additional columns in the added data, you can select to include or exclude these columns under Include additional columns from new data by selecting or clearing the check box for each column.
Optionally, change the settings under
Identify origin of rows.
Select Do not identify origin to skip this option, Create new column to add a new column with different values for data from the original source and data from the added source, or select Use existing column to add the information about where rows come from to an existing column.
- When you are done, click OK.
Example: Editing added rows when matching is broken
In this example, rows have been added from Salesforce to a data table that was originally opened from a local Excel file. The local file was saved using the data loading setting "New data when possible" and it has been reloaded at some time, using Spotfire Analyst. Before the Excel file was reloaded it was modified; the name of the column used in the matching was changed. Therefore, the previous matching of columns is now broken, which is indicated with a red exclamation mark in the Data canvas:
To fix the broken match, first click the settings icon on the Added rows node. This opens the Settings for added rows dialog, and the broken match is indicated with red exclamation marks:
Click on the red exclamation mark and then click Remove match. Add a new match for the renamed column in the original data by clicking on the plus sign next to the new column name and selecting a matching column from the new data.
