Suspending Merges
Once you have initiated a merge, you can suspend it and then resolve it at a later time. Suspending merges allows you to mark the working file to indicate that merging is required. This provides time you may need to investigate conflicts or difference blocks before finishing the merge.
You can only suspend a merge operation if there are changes since the last time you saved the merge result.
To suspend a merge, in Visual Merge, click the Close button on the status bar, then click Yes to mark the working file for merging at a later time. In your Sandbox view, the member is marked with an unresolved merge symbol (), and in the member information pane Windchill RV&S indicates that resolution is required.
