Here's the language from DI-MGMT 81861B, March 2020.

"Para: 1.2.2. Schedule (Comprised of both the Native Schedule File and the Schedule Performance Dataset (SPD)). Provides data from the contractor’s Integrated Master Schedule (IMS)".

So, unless your organization tailored the DID,  the contractor is required to deliver the schedule dataset and the native schedule file.  Suggest you review the contract to confirm the language related to the Schedule and then have your leadership request compliance, if necessary.
