Access Select Query recordset not Updateable - ms-access

Question

I have a Access 2010 Form that is linked to Sql Server and I am using a select query that works correctly until I add an Inner Join and then the field becomes unable to update (Recordset is not Updateable) This is the query I am using but cant check the field Yes(this is a checkbox), if I remove the inner join it works. column nm has can have more than one name in it so to get the latest name I am using the inner join with the max to give me the latest name otherwise it will show both names in the nm column.
SELECT tblA.Reference
TblA.Yes,
TblA.Nm,
TblA.PKID
FROM TblA
INNER JOIN (
SELECT
Reference,
max(PKID) AS TRANID
FROM TblA
GROUP BY Reference) AS TblB ON TblA.Reference = TblB.Reference AND
TblA.PKID = TblB.TRANID)
WHERE TblA.Reference Like "*" & [forms]![NewPayments]![Combo1] & "*" AND
TblA.Nm Like "*" & [forms]![NewPayments]![ClientName] & "*" AND
TblA.Account Like "*" & [forms]![NewPayments]![ACN] & "*" AND
TblA.Query Is Null ;

Answer 1

If you want to use aggregates only to select specific entries, you can use EXISTS instead of INNER JOIN to keep the query updateable.
SELECT tblA.Reference
TblA.Yes,
TblA.Nm,
TblA.PKID
FROM TblA
WHERE EXISTS (
SELECT 1
FROM TblA As TblB
WHERE TblA.Reference = TblB.Reference
HAVING TblA.PKID = max(TblB.PKID)
) AND TblA.Reference Like "*" & [forms]![NewPayments]![Combo1] & "*" AND
TblA.Nm Like "*" & [forms]![NewPayments]![ClientName] & "*" AND
TblA.Account Like "*" & [forms]![NewPayments]![ACN] & "*" AND
TblA.Query Is Null ;
