Version In DRM disappeared after services restart

I have encountered a situation where Version and Hierarchies we created were washed out after services were restarted.

I believe we didn't commit the changes to database hence after services restart system rollback the changes which were committed earlier so my Versions / Hierarchies got deleted. 

I tried reproducing the issue and I was succeeded.

Let me show you how it works in this post.

Created a version and DON’T SAVE IT

Tick mark in Saved column indicates whether version is saved or not besides you can see Baseline version for saved version.

DRM allows you to create Hierarchies under Saved / Unsaved versions.

Restart the services and see the magic

Version created recently was no longer available.

So it is clear that we must save the version the moment when it creates otherwise it will go away during service restart.

Happy Learning  :)
