ZCH_DATA_MGMT_SNAPSHOTS
Stores a snapshot of a member within a data set. If member data is stored outside the set, the snapshot content is captured by resolving the record ID of the member using the REST resource of the corresponding object. Alternatively, member data can be stored as part of the set by uploading the snapshot content when the member is added to the set.
