The CPC Edit transaction allows a merchant to add corporate Level II and Level III data to an approved financial transaction. 

For online transactions, if the transaction request contains CPCReq set to Y, and the Issuer identifies the associated card as a Corporate Purchase Card, the response message will contain a value in the CPCInd field indicating the specific card type of business, corporate, or purchasing card. 

CreditAccountVerify will also return the CPCInd value.
