The Query HCP step uses the Metadata Query Engine (MQE) to query your Hitachi Content Platform (HCP) repository for objects, their URLs, and system metadata properties. You can use the resulting object URL to define HCP object and custom metadata locations for the PDI Read metadata from HCP and Write metadata to HCP steps.
Note: After modifying an HCP object, your change may not be immediately reflected in your query results of the HCP repository until the search index has been updated.
