MAM 7.6.1.2:Ad-hoc reports --> Summarize tab:
I can't create a total if
Exclude Attributes Mode=Yes in the ROS child object.

I get an error when I click the Add Values button:
"BMXAA8992E - The summary was not created. Ensure that the name of the field is correct."I can workaround that issue by setting
Exclude Attributes Mode=No in the ROS child object.

(Note: I hadn't actually excluded any fields yet via the Exclude/Include fields action, although I had planned to. https://i.stack.imgur.com/XNCNY.png )
That field was read-only, so I deleted the child object and re-created it – but with
Exclude Attributes Mode=No.
Now, I can create totals in the Summarize tab without issue.

Summary:
It's good that the workaround was successful.
But does anyone know why
Exclude Attributes Mode=Yes would cause that error in the Summarize tab in ad-hoc reports?
