On Dashboard A, you have Sheet 1, Sheet 2 and Sheet3. On Dashboard B, you have Sheet 2 and Sheet5.
If the action is using Sheet1 as the source sheet and the target is Dashboard A-->Sheets 1, 2 and 3, then Sheet 2 on Dashboard B will also be effected (even if there is no action that goes from Dashboard A to B). However, the only way for Sheet1 on Dashboard A to effect all the Sheets on Dashboard B, the action will have to take the user to Dashboard B.
Does this make sense? Does this answer your question? I hope it helps!
Yes, I was hoping I could update dashboard B without moving to dashboard B, since the information is also updated on dashboard A.
Thanks so much. at least it confirms what I was seeing.
