R/3 did not have the ability to encrypt credit card numbers until

recently. This functionality can be added to your system by applying

support package 46 in 4.6C or support package 22 in 4.7.

The functionality can not be installed via manual application of OSS

notes and it's not available in prior releases of R/3. That said, if

you need it in a release before those my company does have a solution

that will work with any version of SAP - and it allows for roles-based

decryption of credit card numbers in any SAP screen where credit card

numbers are viewed. If you have a certain custom security object in

your profile you can decrypt cards - otherwise you see a reference

number followed by the last 4 digits of the true card number.

I would suggest you first look into SAP's new functionality. Start by

looking at these OSS notes:

633462 - Encryption of credit card data

766703 - FAQ Credit card encryption in R3 System

662340 - Encryption Using the SAPCryptolib

SAP's functionality does allow for masking of card numbers, but it only

masks the first 11 characters as I recall - instead of all but the last

4. They hardcoded that for some reason

Hi Vinod,

Masking is basically used to formatting date and time fields as per the required format in SAPscripts...

The command used in ABAP is SET DATE MASK and SET TIME MASK.

Syntax:

/: SET DATE MASK = 'date_mask'

/: SET TIME MASK = 'time_mask'
