Using Count(*) as a table filter

Question

Good morning, I’m breaking my head with the following code:

select
ac.cd_agenda as "Código Agenda",
m.nm_pessoa_fisica as "Médico",
esp.ds_especialidade as "Especialidade",
a.ds_complemento as "Agenda",
to_date(ac.dt_agenda, 'dd/mm/yy') "Data",
count(ac.cd_convenio) as "Convênios na Data",
acr.qt_permissao as "Cota",
a.ds_orientacao as Rótulo

from agenda_consulta ac

       join agenda a on a.cd_agenda = ac.cd_agenda
       join setor_atendimento s on s.cd_setor_atendimento = a.cd_setor_agenda
       join pessoa_fisica m on m.cd_pessoa_fisica = a.cd_pessoa_fisica 
       join agrupamento_setor ase on ase.nr_sequencia = s.nr_seq_agrupamento
       join especialidade_medica esp on a.cd_especialidade = esp.cd_especialidade
       join agenda_consulta_regra acr on acr.cd_agenda = ac.cd_agenda

where ac.cd_convenio = '55'
and acr.cd_convenio = '55'
and ac.dt_agenda > sysdate
and acr.ie_periodo = 'D'

group by ac.cd_agenda,
m.nm_pessoa_fisica, 
esp.ds_especialidade,
a.ds_complemento,
to_date(ac.dt_agenda, 'dd/mm/yy'),
a.ds_orientacao,
acr.qt_permissao

having count(ac.cd_convenio) < acr.qt_permissao

order by ac.cd_agenda

The current table returns me all dates where the number of agreements is <= to the quota value of this agreement. But I need the table to return me from these dates only the days on which the criterion

ac.ie_status_agenda = 'L'

is hit.

The problem is, in order to count how many patients we have for the insurance I had to include the filter

ac.cd_convenio = '55'

and ie_status_agenda = 'L' always has the value of cd_convenio null.

I am available for further clarification, my first time posting here, I do not know very well if I made myself clear.

I appreciate any suggestion!
