I have two dataflows that have been working for months and still refresh successfully. The issue I have is that when editing either of them now, then clicking save and close, I get an error message s...
+1 Same here. Til today I'm still facing similar issue.
1. Tried refreshing the dataflow>> no error, then open the edit window, without editing click "Save & close" then error message
2. Then tried to edit the query of the dataflow>> preview of dataflow all ok BUT once "Save & Close" clicked then start validating queries then not long after error message appears.
Tried numerous time still the same issue. Even tried doing the same query step by creating new dataflow. Can't proceed to "Save & Close"
Either of this 2 error message will appear no matter how many times I tried.
