Working with Groups
You use groups in a Router transformation to filter the incoming data. Informatica Cloud uses the filter condition to evaluate each row of incoming data. It tests the conditions of each user-defined group before processing the default group. If a row meets more than one group filter condition, Informatica Cloud passes the row multiple times.
A Router transformation has the following types of groups:
- •Input. Informatica Cloud copies properties from the input group fields to create the fields for each output group.
- • Output. There are two types of output groups:
- - User-defined groups. You create a user-defined group to test a condition based on incoming data. A user-defined group consists of output ports and a group filter condition. Create one user-defined group for each condition that you want to specify. Informatica Cloud processes user-defined groups that are connected to a transformation or a target.
- - Default group. The default group captures rows that do not satisfy any group condition. You cannot edit, delete, or define a group filter condition for the default group. If all of the conditions evaluate to FALSE, Informatica Cloud passes the row to the default group. If you want to drop rows that do not satisfy any group condition, do not connect the default group to a transformation or a target.
You can modify a user-defined output group name. Click on the row to open the Edit Group Name dialog.
Guidelines for Connecting Output Groups
Note the following guidelines when you connect the Router output groups to downstream transformations:
- •You can connect each output group to one or more transformations or targets.
- •You cannot connect more than one group to one target or a single input group transformation.
- •You can connect more than one output group to a downstream transformation if you connect each output group to a different input group.
