Hello,

I understand you are asking a question regarding Set Operations.

Set Operations can be performed within an analysis, you can read more about it here :
https://docs.oracle.com/en/cloud/saas/otbi/otbi-user/advanced-techniques-combine-columns-display-data-differently.html

But Set operations cannot be performed on the fly or on demand between 2 objects/analysis that are part of the dashboard, however you can have a third analysis on the dashboard that creates a set between 2 other analysis that you are using in the dashboard.

If my response has answered your question or assisted you with your concern, please click "yes" below to accept the answer or comment with any additional queries. You can also read the Cloud Customer Connect Guidelines for Accepted Answer
