This is for my own search in the future, this works:
```
WITH LastEntries (ProjID, pl_insert, pe_insert)
AS
(
SELECT projid,
max(InsertDate),
(SELECT max(insertdate) FROM project_extras where projid = e.projid)
FROM project_list e
GROUP BY projid
)
SELECT count(c.CreatedDate), a.Status, a.ProjID, a.Project_Name, a.Manager
FROM Project_List AS a
LEFT JOIN Project_Extras AS b
ON a.ProjID == b.ProjID
AND
b.MonthlyRpt = 'y'
AND
b.BudgetYear = '2021'
LEFT JOIN Project_Highlights AS c
ON b.ProjID = c.ProjID
AND
c.CreatedDate LIKE '2021-07-%'
LEFT JOIN LastEntries AS d
WHERE
a.Status == 'Acknowledged'
AND
a.InsertDate = d.pl_insert
AND
b.InsertDate = d.pe_insert
AND
a.ProjID = d.projid
GROUP BY a.ProjID
ORDER BY a.Manager, a.ProjID
;
```
thanks for all the help.
