Similar to Pipelines, pinning a sample file to a Mapping Group allows the impact of the Mapping Group on the data to be previewed.
To pin a sample file:
Select the Files tab of the Column-Files navigation pane.
Hover over a sample file and click the pin icon.
The Match Columns dialogue box will open.
Associate the columns from the sample file to the columns defined in the Mapping Group.
📓 The column name in the sample file is not required to match the column name in the Mapping Group.
The preview pane shows the impact of the Mapping Group on the primary column selected from the sample file. Whenever the Mapping Group is saved, the preview pane updates to show the impact of the updated mapping rules.
