Hi, can you clarify the business drivers\use case behind this requirement, as the duplication of records\data does not normally result in value add to the business.

There are a few community posts that cover creating a table via script, but this may not be best practice as is not driven by vendor published documentation.

basic process would be create
Table

ACL's
Server side scripts (BR's)
UI functions (UI policies\client scripts)
Default form\list views - if the table is extended from another, opening list\form view results in a copy from the parent list\form.
Then copy your data
