Replacing BC with SAP XI-URGENT

[Former Member]

Hi Experts ,

I have a query related to a case in which we want to replace SAP BC with SAPXI.

The client is going for an upgradation from SAP R/3 4.6 c to ECC 6.0 and they have architecture like 4.6c--- BC-SAP Adapter--- Customized Adapters(Third party).

The customized adapters make synchronous RFC calls to 4.6 c through SAP Adapter and BC.

Basically MQ series flow is there between customized adapter and SAP ADAPTER which further updates R/3 through BC.

Now they want to upgrade from 4.6c to ecc 6.0 and replace BC with SAP XI without making any changes to SAP Adapter and customized adapters

Now my questions are :-

1) If i replace BC with SAP XI will there be any development changes required or it will be only configuration changes that can be done by BASIS?

2)Is it possible that Third Party continues to make RFC calls to XI and XI make RFC calls to R/3.

3) In XI we will be configuring JMS adapter for MQ series or MQ series adapter.

4) What difficulties can be faced during replacement of BC with SAP XI ? What can be the impact of replacement?

I would appreciate an early response as this is very urgent.

<i>1) If i replace BC with SAP XI will there be any development changes required or it will be only configuration changes that can be done by BASIS?</i>

There would be development changes that need to be done in IR and ID. The manual process in IR and ID would be dependent upon the customization of SAP BC packages.

<i>2)Is it possible that Third Party continues to make RFC calls to XI and XI make RFC calls to R/3.</i>s

Yes. But u have an option of replacing it completely with the funcitionalities present in XI

<i>3) In XI we will be configuring JMS adapter for MQ series or MQ series adapter.</i>

U may use JMS adapter

<i>4) What difficulties can be faced during replacement of BC with SAP XI ? What can be the impact of replacement?</i>

Difficulty for moving the following objects

1. Mapping the BC propreitary functions.

2. Complex usage of flow services.

3. Java classes usage.

Impact would depend upon ur implementations. There r some tools in market that aid this migration process.

Only some parts of the SAP BC can be migrated to SAP XI like xslt mappings

yes, 3rd party can make calls to XI and XI will make RFC calls to R/3 calls using the RFC adapter in XI.

> series or MQ series adapter.

you will have to configure the JMS adapter in XI.
