Why does this Stored Procedure work from Server Explorer, but not when called by an SSRS Report or my app?

I recently updated a Stored Procedure; I changed the last part of it from this:

SQL

SELECT TC.PlatypusDESCRIPTION, TC.MemberName, TC.WEEK1USAGE, TC.WEEK2USAGE, TC.USAGEVARIANCE,
    TC.WEEK1PRICE, TC.WEEK2PRICE, TC.PRICEVARIANCE, TC.PRICEVARIANCEPERCENTAGE
    FROM #TEMPCOMBINED TC
    ORDER BY TC.PlatypusDESCRIPTION, TC.MemberName;

...to this:

SQL

SELECT TC.PlatypusDESCRIPTION, TC.MemberName, SUM(TC.WEEK1USAGE), SUM(TC.WEEK2USAGE), 
    SUM(TC.USAGEVARIANCE), AVG(TC.WEEK1PRICE), AVG(TC.WEEK2PRICE), AVG(TC.PRICEVARIANCE), 
    SUM(TC.PRICEVARIANCEPERCENTAGE)
    FROM #TEMPCOMBINED TC
    GROUP BY TC.PlatypusDESCRIPTION, TC.MemberName
    ORDER BY TC.PlatypusDESCRIPTION;

...to eliminate some duplicate records I was getting (the PlatypusDESCRIPTION and MemberName combination should always appear on one row).

It works just fine from Server Explorer; I can execute the SP, provide the parameters, and it returns the data I expect.

However, the SSRS report that uses this SP no longer works - it leaves the values for all columns from TC.WEEK1USAGE on blank (only the values for PlatypusDESCRIPTION and MemberName display); and when I run it from my custom Winforms app that calls the SP, it gives me an error message about the table not having a field named "" What?!? That field is there, as you can see.

Why would the SP run in Server Explorer, but balk when called from SSRS and elsewhere?

Use Sql Profiler to see exactly what is getting sent from Winforms App and from SSRS.

I solved it; I had to explicitly give the aggregated fields names like this:

SQL

SELECT TC.PLATYPUSDESCRIPTION, TC.MemberName, SUM(TC.WEEK1USAGE) AS WEEK1USAGE, SUM(TC.WEEK2USAGE) AS WEEK2USAGE, 
SUM(TC.USAGEVARIANCE) AS USAGEVARIANCE, AVG(TC.WEEK1PRICE) AS WEEK1PRICE, AVG(TC.WEEK2PRICE) AS WEEK2PRICE, 
AVG(TC.PRICEVARIANCE) AS PRICEVARIANCE, SUM(TC.PRICEVARIANCEPERCENTAGE) AS PRICEVARIANCEPERCENTAGE
FROM #TEMPCOMBINED TC
GROUP BY TC.PLATYPUSDESCRIPTION, TC.MemberName
ORDER BY TC.PLATYPUSESCRIPTION, TC.MemberName;

...Now it works in all instances.
