Document identifiers

Document identifiers

You can add document identifiers to data in a model to identify the sample file that the data is based on. Each sample file is identified by a unique ID.
Intelligent Structure Discovery
adds document identifiers to groups in the model.
For example, add document identifiers to a model if you want the Structure Parser transformation to join output groups that are based on the same file and output them to a single target.
To add document identifiers to the
intelligent structure
, select the top node in an
intelligent structure
, right-click the node, and select
Add a Document ID
. To remove document identifiers, right-click the node and select
Remove a Document ID
.
In the model, document identifier fields appear in the Table tab, in the following format:
<group name>_documentId
. For example, for a group named "organization" the document identifier field is
organization_documentId
.
In the Structure Parser transformation, a document identifier output port appears for each output group.
