Hi gurus, I am not able to use COUNT with DISTINCT on TIMESTAMP field. Below is my CDS view please help. I want to put COUNT on ConfirmedDate field to get total no of picks per day by user...

for first red box count should show 2 and show only one line (Group by WarehouseNo and Processor)
for second red box count should show 3 and show only one line (Group by WarehouseNo and Processor)
Below is my CDS
@AbapCatalog.sqlViewName: 'ZXEWMIWT'
@AbapCatalog.compiler.compareFilter: true
@AbapCatalog.preserveKey: true
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'Interface View for Warehouse Task detail'
@OData.publish: true
// I* type:ddls
define view ZXEWMI_WT as select from /scwm/ordim_c as ORDIM_C {
key ORDIM_C.lgnum as WarehouseNo,
@UI.selectionField: [{ position: 1 }]
@UI.lineItem: [{ position : 1 }]
ORDIM_C.processor as Processor,
@UI.lineItem: [{ position : 2 }]
//count(distinct ORDIM_C.confirmed_at) as sum_wt
tstmp_to_dats( ORDIM_C.confirmed_at,
abap_system_timezone( $session.client,'NULL' ),
$session.client,
'NULL' ) as ConfirmedDate
}where processor <> ''
group by lgnum, processor, confirmed_at;
Thanks-
Abhishek
