Summarizing monthly data
Hello All -
I've been struggling with creating a monthly summary of defects detected. My table has Project ID, Application ID, Month and Discovered defects. I need to summarize the discovered defects by application and month. Since an application can be tied to multiple projects in a month, I need Project ID to filter which applications should be included in the display.
I've tried mulitple things and cannot get a monthly total by application, including SUMMARIZE, SUM, SUMX, GROUPBY, SUMMARIZECOLUMNS. Usually I get the message: "The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value." I'm thinking this is because I do not including the Project ID in the calculation.
Any suggestions on how to get monthly totals by application?
Using the suggested posting, I was able to get this to work. Actual code is:
SUMX(CROSSJOIN(values('Reliability by Appllication (2)'[Appl_ID]),values('Reliability by Appllication (2)'[Reporting Month])),CALCULATE(SUM('Reliability by Appllication (2)'[Discovered Defects])))
I now get a monthly total of defects by application.
Thanks for the suggestion.

There seems to be a similar issue in this thread: https://community.powerbi.com/t5/Desktop/SUMMARIZE-error-The-expression-refers-to-multiple-columns-cannot/td-p/18456 Does that help?
Failing that, can you post the measure that is giving you grief, and an idea of how you want to use it in a visual - e.g. table/ matrix/ card, columns/rows you need ?
Cheers.
