Hi Anshuman,
The time-slice which you have mentioned is fine as the Rate Determination covers all the periods, are you getting this error even now?
Also, please check SAP note '1554782 - ES31 / EC30: Inconsistent rate determination' whether this is applicable to you, if so perform the post implementation activities described in the note.
Thanks,
