## Rule ID

**SN-0093**

## Impact

Repeatedly importing data that has not changed leads to many skipped rows and unnecessarily bounds system resources.

## Remediation

Ensure that each import is not importing all records every time by using the “Use Last Run Datetime” option. If you are running a JDBC import, use the last run datetime option in your import set Data Source. For a type of File import, be sure that whatever is generating your files is only adding data that is new, or has been changed.
