To fix a broken task, first ascertain the best way to fix the existing task.
Next, create a task to fix the existing task (using the Create Fix Task dialog box), A relationship between the fix task and the bad task is created automatically.
When you create a task, it is automatically assigned to you and set as your current task.
A fix task is a regular task with a special relationship to the completed or excluded (broken) task that it fixes. Sometimes these tasks need to be dependent on each other; sometimes they must not be used together, as explained in following.
If you have good changes in the bad task that must be included in the build, then you must include the excluded (broken) task back into the appropriate project grouping. This means that the bad task and the task that fixes it both are in the build. After you have created the fix task and the relationship between the two tasks and completed the fix task, you can remove the exclusion on the bad task.
If the excluded task contains changes that are moving the product in the wrong direction, and the fix task contains changes that correct this problem, then you need not include the excluded task again.
Next, finish the work that fixes the bad task.
Last, finish the fix task and all associated objects.
If you created a fix task by using the Create Task dialog box, create the relationship between the fix task and the bad task.
