Q. Whenever I attempt to finalize a transaction with a tip amount that is large compared to the initial authorization, I get Invalid Tip Amount error.
A. In the version 4.1 SP2+ use the following setting in 911_ccv.ini
;Specifies the percentage limit on tip amount over the base amount during finalization.
;Values: number in percentage, 200 means 200%, which is 2 times the base amount
;Default: 200

Set to the desired percentage or '0' to disable the setting.
