ACCESS UPDATE OFF OF QUERY

Question

UPDATE dbo_enrollment AS A INNER JOIN Get_New_PCP AS B 
ON A.PartD_ID = B.PartD_ID SET A.Nbr = B.['UpdatePCP'];

So Get_New_PCP is a query I run to get all the changed values from the database with the latest import file.

The error I'm getting is that I Operation must use an updateable query...

Pretty familiar with SQL, and Access- I may have come across this issue before actually, is there any way to work around it without making a table out of the query results? I thought it would act like a view...I tried to research it, but ACCESS UPDATE QUERY in my search just returns a bunch of update query syntax...

Any help would be much appreciated.

Thanks!

UPDATE

SELECT 
c.MaxLoadDate, 
a.CMS_Status_Update_Date, 
a.Effective_Date, 
a.PBP_Nbr, 
a.Unique_Member_ID AS EnrolleeID, 
a.First_Name+', '+a.Surname AS Enrollee, 
a.Street_Address1, a.Street_Address2, 
a.City, 
a.State, 
a.Zip, 
a.Birth_Date AS DOB, 
"(" & Left(d.[Phone],3) & ")" & Mid(d.[Phone],4,3) & "-" & Mid(d.[Phone],5,4) AS PCP_PhoneNumber, 
a.HIN, 
a.PartD_ID, 
b.[Eff Date], 
b.[PID] AS ['UpdatePCP'], 
a.PCP_Nbr AS ['CurrentPCP'], 
IIf(c.PartD_LIPSL Is Null,'W/o LIS','LIS') AS LISStatus
FROM ((dbo_enrollment AS a INNER JOIN cards_april2014 AS b 
ON a.PartD_ID = b.RecNum) 
LEFT JOIN 
GetMaxDateForLISUpdate AS c ON a.HIN = c.HIN) 
LEFT JOIN [CCAPM2] AS d 
ON a.PCP_Nbr = d.PID
WHERE (((a.PCP_Nbr)<>b.[PID]) And ((a.CMS_Status)='Enrolled'))
DESC;

I'm guessing the GetMaxDateForLISUpdate query joined into Get_New_PCP query is the issue. Queries involving aggregates cannot be updated. Check here for options on working around this issue.
