Filtering Fields from the Merge Node

Merge nodes include a convenient way of filtering or renaming duplicate fields as a result of merging multiple data sources. Click the Filter tab in the dialog box to select filtering options.

The options presented here are nearly identical to those for the Filter node. There are, however, additional options not discussed here that are available on the Filter menu. See the topic Filtering or renaming fields for more information.

Field. Displays the input fields from currently connected data sources.

Tag. Lists the tag name (or number) associated with the data source link. Click the Inputs tab to alter active links to this Merge node.

Source node. Displays the source node whose data is being merged.

Connected node. Displays the node name for the node that is connected to the Merge node. Frequently, complex data mining requires several merge or append operations that may include the same source node. The connected node name provides a way of differentiating these.

Filter. Displays the current connections between input and output field. Active connections show an unbroken arrow. Connections with a red X indicate filtered fields.

Field. Lists the output fields after merging or appending. Duplicate fields are displayed in red. Click in the Filter field above to disable duplicate fields.

View current fields. Select to view information on fields selected to be used as key fields.

View unused field settings. Select to view information on fields that are not currently in use.
