Communication with the Open Item Management System

Purpose

This process enables the Account Management (FS-AM) component to communicate with the open item component by means of an open item proxyto determine information about open items .

You can install all application components of Generic Accounts Receivable and Payable (FI-CAX) in one logical system, such as Q5FCLNT076. You can also install all application components of FS-AM in a different logical system, such as K05CLNT510. The process runs on the basis of the standard settings supplied by SAP, as described in this document.

This process uses a multi-system landscapewith different logical systems in which accounts are created in the FS-AM system and are mapped to the contract accounts in the open item component of the FI-CAX system.

In addition, you can define the technology with which your logical systems communicate with one another for each proxy method.

Prerequisites

To ensure communication between the account-managing system and the open item-managing system, the following steps must be performed:

The same business partner used for the creation of a loan contract in FS-AM must exist in FI-CAX as well. This can be created automatically by the "business partner replication process", so that when a business partner is created in FS-AM, it is replicated in the FI-CAX system as well. This is done through ALE Customizing.For more information, see Customizing for Data Replication by choosing SAP Business Partner for Financial Services Settings for Financial Services Interfaces/Data Exchange Data Replication Activate Function Modules.

Also when business partner is replicated, all BP data along with BP Role information is replicated. The customer must make sure that this role exists in the FI-CAX system as it is in the FS-AM system.
The clearing account specified in the contract you create in the FS-AM system must be mapped to the contract account in the FI-CAX system. Contract Account creation will happen automatically from SP1 Release of FS PP1.0.

Process Flow

The Communication with the Open Item Management System process runs as follows:

This graphic is explained in the accompanying text.

The process flow of the Communication with the Open Item Management System process in the components involved:

Receives payment distribution items from the Clearing Account system (Clearing Account in FS-AM)

The Payment Distribution system in FS-AM requires payments to start the clearing process for open items. The clearing account system receives payment items from the Payments system and creates payment distribution itemswithin the payment distribution system. These payment distribution items are linked to their respective payment items.
Forwards payment distribution items along with the payment lot ID (Payment Distribution in FS-AM)

The Open Item Management system in FI-CAX requires information about the payments made in order to clear open items. The payment distribution component in FS-AM generates a payment lot ID for each payment distribution item.
Creates and manages payment lots using the payment lot IDs (Open Item Management FI-CAX)

Open Item Management (OIM) in FI-CAX uses each payment lot ID received from FS-AM to create a corresponding payment lot. Open Item Management next appends the payment distribution item to the payment lot, closes the payment lot, and finally releases the payment lot. This results in posting of payments in the payment lot to Open Item Management where open items are cleared.
Clears open items (Open Item Management FI-CAX)

Payment Distribution decides which open items are to be cleared based on payment distribution rules defined for incoming payments and sends this information to Open Item Management in FI-CAX along with the payment distribution items and the payment lot ID. Open Item Management applies this information to clear the open items.
Sends clearing notification of open items which were cleared (Open Item Management FI-CAX)

Payment Distribution in FS-AM requires information about all cleared items in order to complete the clearing process. Open Item Management in FI-CAX sends a notification to the payment distribution component about the items that were cleared.
1. Sends clearing notification of open items which were not cleared (underpayment scenario) (Open Item Management FI-CAX)
  
  Payment Distribution in FS-AM requires information about all cleared items in order to complete the clearing process. Open Item Management in FI-CAX sends a notification to the payment distribution component about the items that were not cleared.
2. Sends clearing notification of extra payments made over all open items (overpayment scenario) (Open Item Management FI-CAX)
  
  Payment Distribution in FS-AM requires information about all cleared items in order to complete the clearing process. Open Item Management in FI-CAX sends a notification to the payment distribution system about any excess payments remaining after all open items are cleared.

Result

The Open Item Management system (FI-CAX) has replied to the request for information on cleared items from the Payment Distribution system(FS-AM). The requesting system can now process this information further.
