Composite key separator

Please can you provide specific instruction how to change the composite key separator for a table using server events.
I can’t see anything in the manual about this.

Assume you’re using v2020, then simply try this:Config(“COMPOSITE_KEY_SEPARATOR”, “#”); // change from default value comma (,) to hash (#)

But where should i put this?

Put it in “Global Code” under the following locations: “Server Events” → “Global” → “All Pages”.
