how are amounts related to garnishment determined? (example provided)

Hello, could you help me to understand how the "Disposable Earnings" and "Less Exemption" amounts in the "Garnishment" section is determined? Are there any menu paths or configuration or tables that I should look at that provide this information? I have an example of a paycheck - see attached file "garnishment_screenshots-oracle_022625.xlsx". In this particular example, the "Less Exemption" amount is greater than the "Disposable Earnings". So when this happens, no garnishment amount is taken? Will this amount be taken in a future period or not be taken? Thanks for your help.
