(
select custno, slipno, category, donation
, case
when category = 'CREDIT'
then 'N/A'
else custno
end
from a
)
, prep (custno, slipno, category, donation, debit_custno, rn, rdt) as
(
select dc.*
, row_number () over (partition by debit_custno, category order by donation, slipno)
, sum (donation) over (partition by debit_custno, category order by donation, slipno)
from got_debit_custno dc
)
, r (custno, slipno, category, donation, debit_custno, rn, rdt, mn) as
(
select custno, slipno, category, donation, debit_custno
, case
when rn = max(rn) over (partition by debit_custno, category)
then rn
end
, rdt, 1
from prep
where rdt <= 27000 or rn = 1
union all
select p.custno, p.slipno, p.category, p.donation, p.debit_custno
, case
when p.rn = max(p.rn) over (partition by p.debit_custno, p.category)
then p.rn
end
, p.rdt, r.mn + 1
from prep p
join r on p.debit_custno = r.debit_custno
and p.category = r.categoRy
and p.rn > r.rn
and (p.rdt <= r.rdt + 27000 or p.rn = r.rn + 1)
)
select custno, slipno, category, donation
, dense_rank () over (order by debit_custno, category, mn) as unique_nm
from r)
order by custno, unique_nm, donation

Answer 1

WITH must be the first keyword of the query. The previous statement must be be terminated by ; as:
;WITH got_debit_custno (custno, slipno, category, donation, debit_custno) as
(
select custno, slipno, category, donation
, case
when category = 'CREDIT'
then 'N/A'
else custno
end
from a
)
, prep (custno, slipno, category, donation, debit_custno, rn, rdt) as
(
select dc.*
, row_number () over (partition by debit_custno, category order by donation, slipno)
, sum (donation) over (partition by debit_custno, category order by donation, slipno)
from got_debit_custno dc
)
, r (custno, slipno, category, donation, debit_custno, rn, rdt, mn) as
(
select custno, slipno, category, donation, debit_custno
, case
when rn = max(rn) over (partition by debit_custno, category)
then rn
end
, rdt, 1
from prep
where rdt <= 27000 or rn = 1
union all
select p.custno, p.slipno, p.category, p.donation, p.debit_custno
, case
when p.rn = max(p.rn) over (partition by p.debit_custno, p.category)
then p.rn
end
, p.rdt, r.mn + 1
from prep p
join r on p.debit_custno = r.debit_custno
and p.category = r.categoRy
and p.rn > r.rn
and (p.rdt <= r.rdt + 27000 or p.rn = r.rn + 1)
)
select custno, slipno, category, donation
, dense_rank () over (order by debit_custno, category, mn) as unique_nm
from r
order by custno, unique_nm, donation
