Problem: Changing the symbology of imported point data changes previously imported point data symbology
Using Import File to add points from a Microsoft Excel file to Business Analyst Online causes previously imported points to adopt the same color. This leads to difficulties in differentiating the points.
This is a known issue.
Solution or Workaround
Select a symbol shape different from the original symbol when importing new points to Business Analyst Online.
Click the drop-down menu next to the symbol and change the color of the symbol, then change the symbol shape back to the original shape. This gives the expected result.
