HCM extract for the Work Patterns

Summary:

I am trying to Create the HCM extract for the Work Patterns.

Found below are some User entities. But these user entities not return any data

HWM_EXT_WORK_WORKDAY_PATTERN_UE,

HWM_EXT_WORK_SCHEDULE_PATTERN_UE,
HWM_EXT_WORKDAY_PATTERN_SHIFT_UE

I verified the Query and table referred from these UE are from supply chain tables.

zmm_sr_schedules_vl s,

zmm_sr_patterns_vl p.

Any one suggest the correct UE for extracting the work patterns from HCM.

We want to send Work pattern Details if any new one created in the HCM to create same work pattern in the EBS.
