Clear Cache on a Single Signal

[Shamus Cunningham]

I wanted to put together a quick guide on how to clear the cache for a particular signals inside of Seeq Workbench. 

Come common reasons for wanting to clear the cache on a signal

• Data source caching is turned on and you have changed a calculation in your source database 
• You have added prior history to a tag and filled in a gap 

Steps to Clear the cache

1. Open Item Properties 
2. Open Advanced Settings 
3. Click "Clear Cached Values"

Is there a set of permissions that a regular user would need to be able to do this for themselves? I just had to help a user clear cache for several signals as the option was greyed out under his account.

Hi David, 

I believe the user would need "Write" access to the item that cache is being cleared on. The user's current level of access can be checked via "Access Control" under Item Properties.

Thanks! Our users had defaulted to read only on the particular data source so updating the access control there enabled the feature.
