SYMPTOM:
When attempting to drill down on an attribute or a metric, users may receive the following error message:

Object name is too long.
CAUSE:
This error is encountered because the new report name being generated has reached the character limit. Any object in Strategy, including reports, filters, metrics, etc., can only have a name that is 255 characters or less in length.
When drilling in a report, a new report is created with the drilled-to level being appended to the previous report's name, thus constantly increasing the length of the report name each time it is drilled. So, if a user drills from "Sample Report" down to the Customer attribute, the new report will be named "Sample Report > Customer."
