Merge
The Merge button (home > Solution > Merge) opens a drop-down list with various merge options. A DMS solution can be merged with another DMS solution, or with a solution saved to JewelFile (select Merge > File).
There are two main working scenario's:
When two users work simultaneously in the same DMS solution, they can merge updates. Whenever an update to an object is saved on one solution, the icon on the Merge button changes into a lightning bolt in the other solution. You can then use the option Merge > Updates from Current Solution to do the merge.
When two users work with the same data in different DMS solutions (both solutions need to have the same CRS), and an object is updated (saved change) in Solution A, the object (or the object's folder) gets a lightning bolt in front of it's icon in the JewelExplorer in Solution B. The user of Solution B can either merge the update with the Merge > DMS Solution option under the Merge button, or use the Objects Updates form.
