When you use Smart Engineering Manager data in an integrated environment, you must use the SmartPlant > Compare > With Tool Document command in the Desktop Client to compare the restored drawing with the version that was published to SmartPlant Foundation. You should make as many manual changes as possible to synchronize the data before publishing the restored documents.
Using the Compare with Tool functionality allows you to see what needs to be deleted as a result of the restore (for example, an object on a document was deleted and the document was published between the time that the backup was created and the restore happened).
Objects that are only graphics without data on the viewable file will not show up as changes in the comparison tables in SmartPlant Foundation. You must pay attention to graphical differences during the comparison process to see what needs to be added back to the viewable file.
