DX_Publication_Parameters

The DX_Publication_Parameters transformation adds placeholders for the publication instance ID and for the publication date in the Data Integration Hub publication repository.

You use the transformation to add the placeholders for publications that use custom mappings with real-time workflows.

Input Ports

Configure input ports for the DX_Publication_Parameters transformation on the Ports tab.

The following table describes the DX_Publication_Parameters input ports:

Port	Type	Description
DXPublicationName	string	Name of the publication. The name must be identical to the name of the publication that the workflow that runs the transformation publishes. The name is not case-sensitive and can contain up to 64 alphanumeric characters and underscores.

Output Ports

Configure output ports for the DX_Publication_Parameters transformation on the Ports tab.

The following table describes the DX_Publication_Parameters output ports:

Port	Description
DXPublicationInstanceId	Adds a placeholder for DIH__PUBLICATION_INSTANCE_ID in the Data Integration Hub publication repository. DIH__PUBLICATION_INSTANCE_ID identifies the data set that the application published. When you create a publication real-time workflow, you connect this port to the DIH__PUBLICATION_INSTANCE_ID column of the target.
DXPublicationInstanceDate	Adds a placeholder for DIH__PUBLICATION_INSTANCE_DATE in the Data Integration Hub publication repository. DIH__PUBLICATION_INSTANCE_DATE is the date and time that the application started publishing the data set. When you create a publication real-time workflow, you connect this port to the DIH__PUBLICATION_INSTANCE_DATE column of the target.
