Delete Query with Conditions from Multiple Tables: Access 2010 - sql

Question

I am trying to delete records from the "AC_DETAIL" Table that meet a certain criteria in the "AC_PROPERTY" Table; however, when I run the query I get the error "Could not delete from specified tables." I am using MS Access 2010 and fairly new to it. Anyone have an idea why this is wrong and how it can be fixed to work?
DELETE
AC_DETAIL.*
FROM AC_PROPERTY
INNER JOIN AC_DETAIL
ON (AC_PROPERTY.YEAR = AC_DETAIL.YEAR)
AND (AC_PROPERTY.NUM = AC_DETAIL.NUM)
WHERE (((AC_PROPERTY.YEAR)="2015")
AND ((AC_PROPERTY.REGION)="CT")
AND ((AC_DETAIL.SOURCE)="BPF")
AND ((AC_DETAIL.SCENARIO)="PRICES")
AND ((AC_PROPERTY.STATUS)="NO-PROD"));

You have mixed the DELETE and SELECT syntaxes, you can't explicitly join tables in a DELETE statement.
With MS Access 2000 I think you could use a workaround like that (I can't test it right now, so I'm not sure it's going to work):
DELETE AC_DETAIL.* FROM AC_DETAIL WHERE EXISTS (
SELECT 1 FROM AC_PROPERTY WHERE
AC_PROPERTY.YEAR = AC_DETAIL.YEAR AND
AC_PROPERTY.NUM = AC_DETAIL.NUM AND
AC_PROPERTY.YEAR = "2015" AND
AC_PROPERTY.REGION = "CT" AND
AC_DETAIL.SOURCE = "BPF" AND
AC_DETAIL.SCENARIO = "PRICES" AND
AC_PROPERTY.STATUS = "NO-PROD"
);
EDIT : If you have a field NUM as primary key in AC_DETAIL table then something like that should work:
DELETE FROM AC_DETAIL WHERE NUM IN (
SELECT AC_DETAIL.NUM
FROM AC_DETAIL
INNER JOIN AC_PROPERTY ON (AC_PROPERTY.YEAR = AC_DETAIL.YEAR) AND (AC_PROPERTY.NUM = AC_DETAIL.NUM)
WHERE (((AC_PROPERTY.YEAR)="2015")
AND ((AC_PROPERTY.REGION)="CT")
AND ((AC_DETAIL.SOURCE)="BPF")
AND ((AC_DETAIL.SCENARIO)="PRICES")
AND ((AC_PROPERTY.STATUS)="NO-PROD"));
);
