nested select statement that pulls data from more than one table

I'm trying to create a nested select statement that pulls data from more than one table. I'm getting an invalid identifier error, which I'm guessing is because the nested select is not referencing both tables correctly. If I try to include only columns from a single table (by using enrol.special_type_id instead of spectyp.special_type_CODE) then I get a datatype error.

Here is what I have so far:

select    enrol.Rep_Start_Year,  uni.university_code, spectyp.special_type_CODE, count(1) as special_type_Count, spectyp.special_type_EN_DESC
          
    FROM (SELECT rep_start_year, period,
                 CASE
                     WHEN spectyp.special_type_CODE not in ('9.99.98', '9.99.99') THEN 'Other'
                     ELSE spectyp.special_type_CODE
                 END
                     special_type_CODE,
                 fee_cat_type_id,
                 uni_institution_type_id,
                 reg_status_type_id
            FROM edcs_unistat.ustat_enrolment_data) enrol

inner join    edcs_unistat.uni_institution_type uniinst
on              enrol.uni_institution_type_ID = uniinst.uni_institution_type_id

inner join    
(select u.UNIVERSITY_ID,
    (case 
        when U.UNIVERSITY_CODE = 'DOMC' then 'CARL'
        when U.UNIVERSITY_CODE = 'NOSM-LAKE' then 'NOSM'
        when U.UNIVERSITY_CODE = 'NOSM-LAUR' then 'NOSM'
        when U.UNIVERSITY_CODE = 'LAUR-ALGM' then 'ALGM'
        when U.UNIVERSITY_CODE = 'LAUR-HRST' then 'HRST'
        when U.UNIVERSITY_CODE = 'DOMC' then 'CARL'
        else U.UNIVERSITY_CODE 
     end) as university_code
from edcs_core.university u) uni
on              uniinst.university_id = uni.university_id

inner join   edcs_unistat.special_type spectyp
on           enrol.special_type_ID = spectyp.special_type_ID

inner join  edcs_unistat.reg_status_type regstatus
on          enrol.reg_status_type_id = regstatus.reg_status_type_id

inner join  edcs_unistat.fee_cat_type feetyp
on          enrol.fee_cat_type_id = feetyp.fee_cat_type_id

where       enrol.Rep_Start_Year  in ('2012', '2013')
and         enrol.period in ('FAL')
and         regstatus.reg_status_type_code in ('12','13','14','15','16','18')
and         FEETYP.FEE_CAT_TYPE_CODE in ('3', '4')

group by    enrol.Rep_Start_Year, uni.university_code, spectyp.special_type_CODE, spectyp.special_type_EN_DESC
order by    enrol.Rep_Start_Year, uni.university_code, spectyp.special_type_CODE

u.university_id  is illegal

university only has 2 columns

 UNIVERSITY_CODE
and
UNIVERSITY_EN_NAME

also spectyp is used before it is joined

and uni_institution_type  doesn't have a uni_institution_type_id column

The DDL is a snippet; the real university table has many more columns. The uniinst and uni tables should have had the columns below. How can I join spectyp earlier?

CREATE TABLE "EDCS_UNISTAT"."UNI_INSTITUTION_TYPE" 
   (	"UNI_INSTITUTION_TYPE_ID" NUMBER NOT NULL ENABLE, 
	"UNI_INSTITUTION_TYPE_CODE" VARCHAR2(8 BYTE) NOT NULL ENABLE, 
)

  CREATE TABLE "EDCS_CORE"."UNIVERSITY" 
   (	"UNIVERSITY_ID" NUMBER NOT NULL ENABLE, 
	"UNIVERSITY_CODE" VARCHAR2(10 BYTE) NOT NULL ENABLE,
)

looks like there are several other missing columns from other tables.

It's impossible to tell on this end if "invalid identifier" is because a column is really missing or if it's because you left it out

please post complete DDL for the relevant tables

as in the previous question I've removed the schema names.

I also restructured the query to remove the extraneous subqueries.
They weren't necessary, nor did they help performance but they did create the join-order problem mentioned previously.

  SELECT rep_start_year,
         university_code,
         special_type_code,
         COUNT(*) AS special_type_count,
