Why do I not see the values for Assemble Properties in the new version of model?

I have published a new model version, but Assemble Properties are not updated.

Issue: 

From time to time, the users might encounter an issue where they publish a new version of their model but Assemble Properties won’t get transferred from the older version to the new version. 

Before discussing the solution, let’s look at a Revit parameter called Revit Link ID (Source Document ID in Assemble): 

Source Document ID (Revit Link ID) is a unique identifier for each model. Assemble monitors this number in each version to verify this is the new version of the same model and to ensure avoiding random unwanted data transfer. Please note that Revit Link ID is not visible in Revit’s user interface. 

Cause: 

• When a new version of model is published, Assemble compares the Source Document ID of the older version and the Source Document ID of the new version to make sure they match. If the Source Document IDs match, Assemble then transfers the data from the older version to the newer version by comparing each individual instance’s Source ID (Revit Instance ID). 
• If the Source Document ID (Revit Link ID) changes between the versions, Assemble stops transferring the data even if the Source IDs of the instances in the model match. Activities like unlinking and linking the model again, publishing a version as linked and the other version unlinked, and binding models in Revit might change the Source Document ID (Revit Link ID) of a model. 

Solution: 

Before taking action to fix the issue, please verify the root cause of the issue is in fact unmatching Source Document IDs. In order to do so, you can add “Source Document ID” as a column to the inventory, look at its value in the new version, and then revert to the older version and see if the value is different for the older version. After verifying the root cause, you can follow the steps below: Open the older version of the model in Assemble. 

1. Remove all default columns from the inventory. 
2. Add “Source Document ID” and the Assemble Properties you want to transfer as columns to the inventory. 
3. Export (include all instances) and open the inventory in Excel. 
4. Switch the model version to the new version in Assemble. 
5. Check out the value for “Source Document ID” of the new version. 
6. Change the value of “Source Document ID” for all instances in Excel to match the new version. 
7. Save the Excel file. 
8. Import the Excel file back to the new version in Assemble. The values of Assemble Properties added to the inventory should be now updated.
