"The data is made available for analysis and reporting purposes in the BW system via TransientProviders
which are based on SAP HANA Calculation Views." It lists examples like /IMO/VSTATDTP (TransientProvider for DTP Statistics) based on the HANA Calculation View sap.bw.techcontent.DTPSTATISTICS.

"TransientProvider": "A TransientProvider is based on an SAP HANA model... You can use a TransientProvider to make data from an SAP HANA model available in the BW system for analysis and reporting purposes
without having to replicate the data." This definition directly matches the use case described in the question.

Section 5.4.2 "Technical Content": This section describes the shift from the old statistics concept (0TCT objects) to the new HANA-based technical content. It confirms that data is collected in HANA tables
exposed via Calculation Views
and then made available for reporting in BW through delivered virtual providers
which are Transient Providers.
