You want to create an opportunity without an account linked to it.
Reproducing the Issue
- Go to the Sales work center.
- Go to the Opportunities view.
- Click on New.
- The field Account is marked as mandatory.
The account role is a standard delivered role for opportunities and cannot be changed.
You may want to consider the following alternative - It is possible to delete the account entry from the involved parties table. A custom solution to do this could be implemented. However note that an opportunity without account will be inconsistent and follow up actions may be disabled due to this.
