In an Opportunity on adding the Competitor, the Main checkbox is automatically selected.
Reproducing the Issue
- Go to the Sales work center.
- Go to the Opportunities view.
- Search for the Opportunity ABC (where ABC is the opportunity name) and open it .
- Go to the Competitors facet and click on the Add button.
You can see in the Competitor window which opens, for the role as Competitor the Main check box is selected by default and can not be uncheckd.
The application logic by default marks atleast one Competitor in an Opportunity as the Main.
This is an expected system behavior.
