Alternative to ChangeDocumentCollection for Service Request checklist change history in SSC

[#1]

Hi SAP Community,

we need to extract checklist change history for Service Requests from SAP Service Cloud into SAP Datasphere.
Currently we use: /sap/c4c/odata/v1/changedoclist/ChangeDocumentCollection

with the mandatory filter: BusinessObject eq 'ServiceRequest'
and a date filter such as: ChangeDateTime ge datetime'2025-11-01T00:00:00'

The service provides the information we need, especially old/new values and change metadata:
ChangeDateTime
ObjectNodeElementName
ObjectNodeElementOldContent
ObjectNodeElementNewContent

However, the extraction is very slow and runs into timeouts in SAP Datasphere. 

Extracting the data with date filter such as: ChangeDateTime ge datetime'2026-06-01T00:00:00' is running successful, but we need the data starting from 2025-11-01T00:00:00'.

Is there a better OData service/entity for Service Request checklist change history?
Or is ChangeDocumentCollection the only standard source for old/new value changes?

Is there a supported way to apply a monthly date range filter on ChangeDateTime in the ChangeDocumentCollection?

Thanks!

Best regards
Julian
