BTP CI-Filter condtion set up on oDATA API ( API_SALES_ORDER_SRV) using Date values

[satsunros]

Hello Community,

I need to  set up a filter condition on oData API (API_SALES_ORDER_SRV)

(CreatedByUser eq 'BTPDEVUSER' and (CreationDate ge datetimeoffset'${date:now:yyyy-MM-dd'T'00:00:00.0000000'Z'}- ${property.p_daysInPast}' and CreationDate le datetimeoffset'${date:now:yyyy-MM-dd'T'00:00:00.0000000'Z'}'))

however this filter condition could not help me to get the records at all.
Could you please provide some hints, how this filter condition would be set up

Thanks & Regards,
