Overview
This document attempts to explain in the brief the credit card processing in SAP.
SAP provides a flexible and secure payment card interface that works with the
software of selected partners that provide merchant processes and clearing house
services. In SAP the credit card processing is integrated with the sales and
distribution module.
Payment card configuration
Much of what is required for credit card processing to work with VISA, Master
Card, and American Express is already set up in SAP.
For all credit card configurations refer to
Define Card Types
Transaction SPRO IMG ‡ Sales and Distribution ‡ Billing ‡ Payment Cards
Here we define the type of cards that can be used in the system. A four-letter
code is given for each card type. E.g. MAST for Master Card, VSAJ for Visa
Japan. A function module for checking the card number is also specified here.
1. Define Card Types
Credit Card Configuration And Processing In SAP
Maintain Card Categories
(a) Define card Categories: Here we specify the card category of the
payment card. With this the system automatically determines the card
category when you enter a card number in master data or sales
documents.
(b) Determine card categories: Here we specify the acceptable number
ranges for different card types. Also card categories are assigned to the
card types. Even though SAP comes with card checking algorithms
(Function Modules) for standard card types this configuration setting
is particularly useful to those cards that do not contain any standard
checking algorithm already set up in SAP.
2. Determine Card Categories
Maintain Payment Card Plan Type
In this step, you assign the payment plan type for payment cards, the payment
card plan type, to all sales document types in which you will be using payment
cards. You cannot process payment cards if you have not made this assignment
The standard system contains payment plan type 03 for processing payment
cards. 3. Show the screen where this assignment is done.

3. Maintain Payment Plan Type
Maintain Blocking Reasons
In this step, you define blocking reasons for payment cards. You enter these in
the payer master record to block cards. The standard system contains blocking
reason 01 for lost cards.
Risk Management for Payment Cards
Transaction SPRO IMG ‡ Sales and Distribution ‡ Billing ‡ Payment Cards
‡ Authorization and settlement ‡ Risk Management for payment cards.
Risk Management plays a central role within Sales, providing you with checks
and functions to minimize your credit risk. In addition to letters of credit and
export credit insurance, payment cards are among the payment guarantee forms
that you can use to insure payment for sales order items. SAP comes with predefined
payment forms of guarantee as shown below. Customer can also
maintain other forms of payment suited for their line of business.
Credit Card Configuration And Processing In SAP
Define forms of payment guarantee
3. Define forms of payment guarantee
Maintain payment guarantee procedures
In this step, you define Payment guarantee procedure. These procedure controls,
which form of payment guarantee, are valid for a particular customer, and for a
particular sales document type.
The various settings done under this configuration are
Define payment guarantee procedures
Maintain customer determination procedure
Maintain document determination procedure
Assign sales document types
Determine payment guarantee procedures
Maintain authorization requirements*
Here requirements* are set to tell the system how and when to carry out
authorization when a sales order is saved. SAP comes with two requirements
Form routine 1. Carry out authorization only when the sales document is
complete. The system carries authorization when the order is saved.
Form routine 2. Carry out authorization only when the sales document is
complete, but the authorization for all the complete documents is carried out in
batch.
Additional requirements* can be assigned here as per the business requirements.
*Requirements are ABAP/4 code. Requirements for various functions can be accessed using transaction VOFM

4. Maintain Card Authorization Requirements
Maintain Checking Groups
How and when authorizations are carried out depends on the setting you make in
the customizing for maintain checking group routines.
The three main settings that influence authorization are:
a) Authorization requirements
b) Authorization horizon
c) Preauthorization
There are two settings under this setting.
Define checking group: Here a checking group is defined and the
authorization requirement (described in the previous section), Authorization
horizon (described below) and preauthorization settings are done for this
checking group.
5. Define Checking Group
Credit Card Configuration And Processing In SAP
Here you can see a checking group C1 is defined with the authorization
requirement 902. Checking the pre-authorization tells the system to carryout preauthorization
if the order fulfillment date falls outside the horizon. The
authorization horizon specifies the number of days before the material
availability date, or billing date, that the system is to initiate authorization. If a
sales order is saved within the authorization horizon, the system carries out
authorization immediately. If a sales order is saved before the authorization
horizon comes into effect, the system does not authorize at all, or carries out
preauthorization.
6. Preauthorization Concept
In this example, the system has been set to authorize one day before delivery
creation. The system does not carry out authorization when the order is saved on
Day 0, rather on Day 2. Note that the authorization validity period has been set to
14 days in Customizing IMG‡ Authorization and settlement‡ Specify
authorization validity periods. The transaction will have to be reauthorized if
delivery activities take longer than 14 days.
Assign checking groups: Here the checking groups defined earlier are
assigned to different sales document types as shown 8.
Specify authorization validity periods
Here number of days that an authorization can remain valid for different card
types are maintained. Refer to 9.

Account Determination
Transaction SPRO IMG ‡ Sales and Distribution ‡ Billing ‡ Payment Cards‡
Authorization and settlement ‡ Maintain Clearing House
In the following steps, you set the condition technique for determining
clearinghouse reconciliation accounts for authorization and settlement. The
system uses the entries here to determine the clearing account for the payment
card charges. When settlement is run, the postings in the receivable account for
the payment card will be credited and a consolidated debit will be created and
posted to the clearinghouse account. These accounts are a special type of general
ledger account that is posted from Sales and Distribution.
Here, you maintain:
• Maintain field catalog.
• Condition tables and the fields that they contain
• Access sequences and condition types
• Account determination procedures
• You then assign these accounts to condition types.
Add to field catalog
Here you maintain the fields that can be used in the condition table. 10.
Shows the transaction to maintain the field catalog.
10. Maintain Field Catalog.
Maintain condition tables
Here condition tables are maintained with fields that are added to the field
catalog. SAP comes pre-configured with two condition tables 4 and 6. Refer
11.
Credit Card Configuration And Processing In SAP
11. Maintain Condition Table
Maintain access sequences
In this step we define an access sequence and link the access sequence with the
condition tables.
Here an access sequence is defined. SAP comes with the access sequence A001.
12. Define Access Sequence
Once the new access sequence is defined, it is linked to the condition tables as
shown in the next screen.
Credit Card Configuration And Processing In SAP
13. Maintain Access For Access Sequence
Selecting an access and clicking fields will display the fields for the selected
access as shown below for access 10 as shown above.
14. Display Access Fields
Maintain condition types
Here condition types are defined and the access sequence to linked to it.
Condition types are contained in account determination procedures and control
which access sequences the system uses to find condition records.
These are The condition tables.

15. Define condition type
Maintain account determination procedure
In this step an account determination procedure is defined and linked to the
condition type (which in turn is linked to the access sequence).
Define account determination procedure
16. Assign account determination procedure.
Here an account determination procedure CC01 is defined and the condition type
CC01 is assigned to it.
Access sequence linked to the condition type
Credit Card Configuration And Processing In SAP
Assign account determination procedures
In this customizing the previously set up account determination procedure is
assigned to different billing documents.
Assign Accounts (G/L)
G/L accounts are assigned here for the combination of Sales organization, Card
type, chart of accounts and condition types as shown in the 17.
17. Assign G/L accounts
Set authorization / settlement control per account
Each G/L account is assigned an authorization and a settlement function module.
The system will read the configuration a call the authorization and settlement
function module during authorization and settlement respectively.

18. Set Authorization and settlement function module
Maintain merchant IDs per account
A merchant may have one or more IDs for each clearinghouse with which it does
business. Here, you assign these different merchant IDs to their related
receivables accounts.

20. Sales Order Cycle With Credit Card Authorization
When an order is placed through the front-end system, the order information,
credit card information, billing information, shipping information is passed to
SAP. SAP processes the order calculates the taxes, the shipping costs and reads
the configuration information settings and executes the function module setup as
described in Fig. 18. The function module formats the data and makes a RFC *
call to the payment application**.
The payment application screens the order for fraud, encrypts the data and
communicates with the third party processor who in turns communicates with
the card association and card issuer.
*RFC (Remote Function Call)
*Payment Application: Middle ware between SAP and third party processor/bank.
Credit Card Configuration And Processing In SAP
The third party processor responds back with the response whether the
transaction is approved or declined or referred.
Note: When any item in the order does not have a confirmed quantity, then
authorization is not carried out for the full amount. A small dollar amount
usually ($1) is used as the authorization amount. During the rescheduling run
the system will check for the material availability. If the material can be
delivered within the horizon date, a full authorization for the order is carried
out.
Approved: When the credit card transaction is approved the systems checks for
the material availability, confirms the material for the ordered quantity and saves
the order.
Declined: The material availability check for the material is not made, and the
order is rejected.
Referred: The order is saved and is blocked for delivery. In this situation is
merchant calls the bank checks for the available credit on the card and a manual
authorization is carried out.

The first line in payment card screen is the card check performed by SAP system,
using the card check algorithm function module as described in 1. And the
remaining lines represent the actual authorizations that are carried out.

Settlement
Legally the merchant can charge the credit card after the order has been
completely processed. In SAP this happens after a delivery is created and the
goods has been shipped. In case there is not enough authorization for the order
to be delivered, the system goes out the get the authorization for the remaining
amount.
In SAP settlement is initiated using the transaction FCC1. All the valid
authorization is submitted in a batch to the payment application at scheduled
intervals as specified by the third party processor.
The payment application encrypts this data and communicates with the third
party processor. The third party processor checks if the settlement request has a
valid authorization against it. The third party processor then transfers the fund
from the cardholder’s bank to the merchant bank.
