The Create Sync operation is an addition to the list of Cameo DataHub operations. The Create Sync operation will recreate synchronization (DHLinks) if you lose or delete the DHLinks. Before, in order to recreate synchronization (DHLinks), if you lost or deleted the DHLinks you were required to copy the data from the Cameo DataHub to the modeling tool(Cameo) using the Copy Data with Sync operation. This new operation allows you to recreate synchronization(DHLinks) without replicating the data.

The same data source exists in the Cameo DataHub Explorer panel and the Modelling tool without DHLinks

To create sync between existing data

1. From the Operation list in the Cameo DataHub Explorer panel, select Create Sync.
   
   
   
   
2. Drag the parent data set from the Cameo DataHub Explorer panel and drop it over the identical data set in the Containment tree.
   
   
   
   
3. The Create Sync Wizard will appear. Perform the Type/Attribute mapping as you would while using the Copy Data with Sync operation. 
   
   
   
   
4. Select the mapped type, then choose the Key attribute between them. The key attribute will be used to match the values. 
   
   
   
   

5. Once matching results are displayed, do one or several of the following:

   The matching result displays the matched attributes in green(Sync relation created) and unmatched attributes in red(Sync relation not created).

   • If there are key attributes that do not match (highlighted in red) and you want them to be included, select the checkbox for the particular value and click Add Sync.
   • If there are key attributes that match and you do not want them to be included, select the checkbox for the particular value and click Remove Sync.
   • If there are key attributes that do not match (highlighted in red)and you want them to be excluded, select the checkbox for the particular value and click Exclude.
   • Select Ignore all no sync source entities checkbox, if you want all nodes that did not match to be ignored. The synchronization will discover them later.
   • Select Exclude all no sync source entities checkbox, if you want all the nodes that did not match to be marked as Excluded. The synchronization will no longer include them in the operation.
     
     
     
     

6. Click Finish.

   Until every node is marked as synced or excluded, you cannot click Finish.

   

   Once the procedure is finished, the newly created synchronization will be visible as shown in the image below, denoted with the S icon.
