Detecting code duplication in Salesforce
Duplicated code impacts the quality of your Salesforce org. Every block of duplicated code detected across Apex Classes and Apex Triggers generates an issue in instance scans.
The severity of the issue depends on the total number of code lines which are repeated in the Org (size of repeated block x number of lines in the block x number of repetitions).
The minimum token length which should be reported as a duplicate is set to 100.
You can find the code duplication issues on the Duplicated Code dashboard.
