Does preserve data get set on target or instance?

[WiSKy]

I want to make sure I understand the cloning process a little better.  Does 'Preserve Data' for tables and 'Exclude a table' get set on the Source or Target instance?

Thanks in advance, Scott

Hi, Preserve data get set on target instance and Exclude a table gets set on source instance. Please refer https://docs.servicenow.com/bundle/geneva-servicenow-platform/page/administer/managing_data/task/t_CreateADataPreserver.html Please mark my answer correct if it helped you

Hi Wisky,

Exclude Table will leave an empty table on the target instance whereas Preserve Data will preserve data which were on the target i.e There will be no data added from the source instance.

P.S:The system cannot exclude tables that extend the Task table and are also flattened into it as part of the table per hierarchy extension model. Since these extended tables are actually part of the same physical database table, the system clones the data when it clones the Task table. You can exclude tables that extend the Task table under two conditions. Either the system stores the tables in their own physical tables as part of the table per class extension model, or you exclude the Task table itself.

You define the Clone Data Preserver and Clone Exclude Table records on the source instance.  That is where the clone is initiated from so it gets the information from itself.
