Boomi: Retain field mapping

Have you encountered the following scenario before?

I have mapped all the lines between 2 profiles. However, when a new XML schema is imported, all the lines (relationship) just disappeared. I will have to do it again.
How do you prevent this? Let me explain to you how Boomi Map works by the following example:





Take away

By referring to our test above, as long as the full path name matches, the mapping will remain unchanged. For example:
root/parent1/child1.1 remains unchanged (no changes)
root/parent1/child2.1 has changed (mapping disappear)
