As discovery and designer are interoperable, we should be able to open a designer document in discovery and vice versa.
I have a lumira designer document. I am trying to open this in lumira discovery.The lumira designer document is a 10 + tabs report and is based on 10 + BEx queries.
I get the error below on opening the designer document in discovery,
"Error: Document containing multiple online connections can't be opened in Discovery"

What does it mean by document containing multiple online connections?
How to go about this?
regards
Varun
