Using OData query, how to get the 'Progress by all Work Items' rollup column value for a Project?

Hi, VivekGupta 

I’ve pasted your M query in my advanced editor, but I get an error. Would you like to check again?

To get better assiatance, I suggest you to post some sample data in table form or pbix file(without sensitive data) and your expected result.

Thanks in advance!
