Failure analysis and Solution

In the work order of plant maintenance, there is the tab called Solution. You can create different kind of solutions for the problem fixed in the work order and assign them to the work order. Also, there is a failure analysis application in the row menu of the work order where you can define the failure code and desc, analysis code and desc and resolution code and desc and then select them according the need.

Here are my questions:

1) what is the difference betwee the solution tab and resolution in the failure analysis ( I mean when to use under what circumstance)
