Connection of External Systems (SAP Library - Master Contract Management (FS-MCM))

Connection of External Systems

Use

Master Contract Management is currently being prepared technically to connect additional systems so that the following data can be managed externally:

· Accounts

· Business partner

· Payment orders

The aim is to be able to connect other systems remotely to Master Contract Management in future. You will be able to use both SAP components such as the SAP Business Partner for Financial Services and other comparable applications (external systems) as remote systems.

Technology

External systems are connected by way of a corresponding proxy that contains a series of Business Add-Ins (BAdIs). The implementations of this BAdI supplied by SAP enable the usual use of existing systems as standard.

· If you do not want to use an external system, do not change the BAdIs.

· If you want to use a different system, you must create your own implementations for the BAdIs. Within these implementations, you can then implement communication between Master Contract Management and the external system.

Recommendation

We recommend you leave the standard implementations unchanged. See also the Constraints section.

Usage Examples

External Business Partner System

For performance reasons you use two account managing systems in addition to Master Contract Management (MCM): One system with Account Management (AM) only for accounts based on the GIRO product (checking) and a second AM system for accounts based only on the SPAR product (savings). To avoid the need for duplicating the business partner data from one system to the other two, you can connect one of the business partner systems externally, and ensure a parallel access for MCM and the two AM systems.

External Account-Managing System

You want to manage master contracts and their participants in multiple systems, so for example, in an MCM system or in two AM systems and a comparable application (external system).

Master Contract (Planned)

If you use Master Contract Management (FS-MCM) with the Bundle Pricing (FS-MCM-BPR) feature, the master contract can be in MCM and the participant contracts in an external account-managing system (SAP Account Management or a comparable component).

External Payment Order System

If you use the Overdraft Protection and Payment Distribution and Monitoring functions in Master Contract Management, then you need a system in which the corresponding payment orders can be managed. If you use at least one of the functions named, you have the following options:

You want to use Account Management to manage payment orders, and Account Management is in the same logical system as Master Contract Management. In this case, you do not need to do anything, as this is already supported in the standard system.
You want to use Account Management or another product for the management of payment orders in another logical system such as Master Contract Management, and thus connect an external system. In this case, you need to create an implementation for the payment order proxy.

Limitations

External Business Partner System

It is already technically possible to connect a business partner system externally.

Recommendation

For performance reasons, we recommend that you manage the SAP Business Partner for Financial Services (BP-FS), Master Contract Management, and Account Management jointly in one system

External Account-Managing System

It will not be possible to connect third-party external systems to Master Contract Management until a later release. The same applies to managing master contracts and their participants in multiple account-managing systems.

External Payment Order System

It is already technically possible to connect a payment order system externally.

Effects on Customizing

External Business Partner System

You (potentially) connect an external business partner-managing system to Account Management by means of the business partner proxy that consists of a series of Business Add-Ins (BAdIs). The default implementations of these BAdIs supplied by SAP currently allow you to use the SAP Business Partner for Financial Services (BP-FS) in the usual way as standard.

The following IMG activities are available in the Customizing for Master Contract Management under Business Partner Connection ® Business Add-Ins (BAdIs) ® General BAdIs ® Business Partner Proxy:

· BAdI: Create Aliases

· BAdI: Goto Business Partner Display

· BAdI: Import Customizing for Business Partner Roles

· BAdI: Mapping Service

· BAdI: Business Partner Search Help

· BAdI: Read Business Partner Data

· BAdI: Check Restrictability of Business Partner Roles

External Account-Managing System

You (potentially) connect an external account-managing system to Master Contract Management by means of the account proxy that consists of a series of Business Add-Ins (BAdIs). The implementations of these BAdIs delivered by SAP currently enable you, in the standard system, to make normal use of Master Contract Management and Account Management in one system.

To ensure communication between MCM and the account-managing systems, the Contract Category (BCA_DTE_MEMB_OBJECT_CATEGORY) and Contract Type (BCA_DTE_MEMB_OBJECT_TYPE) fields have already been introduced. You use them to map data in the MCM system with that of the remote systems.

In the Customizing for Master Contract Management, the following IMG activities are available under General Settings:

· Define Contract Types

· Assign Contract Types to Keys

· Define Account Identification for Messages

In the Customizing for Account Management, under Product Management ® Product Definition ® Account Products, the following IMG activity is relevant:

· Assign Contract Types to Account Products

Note

Note:

If you create a new client, you must define contract types and then assign a at least one contract key to each new contract type in IMG activity Assign Contract Types to Keys. This also applies if you only use one AM system in addition to the MCM system to manage accounts.

Recommendation

We recommend that you copy the sample Customizing supplied by SAP.

External Payment Order System

To connect an external system for managing payment orders to Master Contract Management, use the payment order proxy. In the Customizing for Master Contract Management, you are provided with the BAdI Connection to the Payment Order System for this purpose. The default implementation of this BAdI supplied by SAP currently enable the usual use of existing systems in the standard system.
