In order to avail credit of input services, does POS need to be in recipient state only?

ex: A from telangana has received some repair services in Delhi, now, POS will be Delhi and cgst & sgst are charged in invoice. Now my GSTR2B is showing non availability of Input with reason, POS lies in the supplier state.

please clarify me on the input availability in this case.
