I am attempting to create a 'report' (more like a listing of rows from a dataset) utilizing ODS Excel and keep running into the "ERROR: The SAS System stopped processing this step because of insufficient memory." problem. I read through a handful of other posts on this topic:

I initially tried using a simple proc print instead of proc report, but that runs into the same insufficient memory error so I assume this to be an ODS Excel issue and not anything with PROC Print or PROC Report. In addition, I can just perform a PROC Export which creates an Excel file ~4.9MB in size. Does it really consume 100x (Export=30,174.40k vs ODS Excel Report=3,658,694.14k) the memory to create an Excel file with ODS Excel vs PROC Export for XLSX? While export is a viable alternative, as part of the script I also create a couple of summaries using PROC Tabulate on separate Excel sheets and was hoping to contain all output in a single Excel file for my end users.
Is the only work around to get MEMSIZE increased? I have reached out to our internal SAS/server team for assistance as well as I am not sure I have any control over
This should also be possible; try it.
This worked with University Edition:
ods excel
file="/folders/myfolders/test.xlsx"
options(sheet_interval="none" sheet_name="class")
;
proc print data=sashelp.class;
run;
ods excel close;
proc export
data=sashelp.cars
file="/folders/myfolders/test.xlsx"
dbms=xlsx
replace
;
sheet="cars";
run;
The EXPORT is much more efficient because it does not set any (or most) cell attributes, which eat a LOT of space on the XML (before compressing).
In my experience ODS is VERY resource intensive. It's fine for creating printed reports, but if you start writing tens of thousands of rows of output it consumes large amounts of CPU and memory. I'm not at all surprised by your findings. PROC EXPORT is a better option in your case.

Any reason to use ODS?
If you really need to, and MEMSIZE is locked, then you might be able to fill in the excel sheet in several passes.
the reason for ODS Excel is because I am also including a couple of summary outputs from PROC Tabulate on a worksheet separate from the listing of the detailed records.
First run the Reports with ODS EXCEL; reports should be fairly small. After the ODS EXCEL CLOSE, open the Excel file with LIBNAME XLSX and use PROC COPY (or DATA steps) to copy the datasets to the workbook.
This should also be possible; try it.
