I have a report which connects to a DB2 table. I want to use "Set Location".

I have a report which connects to a DB2 table. I want to use "Set Location" to swap to the counterpart in Postgress database.

However, the button is greyed out.

I am able to swap table in same db2 system in any locations.

Is it possible to "Set Location" to another database? I'd like to know whether absolutely impossible or there is a way to do so.

Please let me know. Thank you.
