Data identical severities

Hello,

I work with the opportunities and risks that you have developed.
In these two sections, there is the severity field. My problem is that it is supplied with two fields are the same data, I want these fields have different data.

I thought of three different options.

The first is that I change the variable idSeverity by idSeverityXXXX and I create a related table, but then what are the other things I need to create (for example, add headings in the menus, etc. ..) to have the same interactions that share forward? Is there any other things to change (eg the elements in reports, ..). If so, which?

The second idSeverity left, and I think it is possible to change an element idSeverity poitant on another table and the same question arises.

And a third would change the Severity table and add a column indicating which table this field is connected and establish a legacy much like types. But again it's a little fuzzy on how to do and questions still arise.

If you have a simpler proposition, I'm listening.

Regards

Severity is it related to other things? (eg reports) Because I'm afraid that by creating a new object, it generates errors because successive links are not met (a idSeverity in this report or elsewhere)

Is there then other things other than this risk class?
