Oracle Payables R12.1.3 - Credit Card setup. Question about 'Maximum Amounts Per Transaction & Per Period'

Payables > Credit Cards > Credit Cards

What do the fields 'Maximum Amounts' - 'Per Transaction' and 'Per Period' drive? We want to populate these fields and use them for reporting, but we are concerned they will have some unintended business control function. I cannot find what they govern / control.In the Help section for the Form it just says:

Maximum Amount Per Transaction. If you want to override the card holder's authorized amount per transaction, enter the maximum authorized amount. In a future release, this value will override any amount per transaction restrictions you may have set in the Profiles window.
