Integration of CRM with legacy systems

[Former Member]

Hi Experts,

We are planning to implement CRM on SAP Enterprise Portal. There are 2 non-SAP systems and one R/3 system in the system landscape at present, all to be connected to CRM which will be used as a front-end (with EP). Billing happens in the non-SAP system (Genesis?). Communication between non-SAP systems and CRM to be in XML.

Question:

Whether XI is required or whether it would suffice 2 use just CRM Middleware itself for the XML communication?

Any inputs in this regard are highly appreciated.

Using XI we can choose both SAP based ABAP proxies as well as Web proxies supporting Java based JMS queues or say XML based adapters hence the integration to SAP & Non SAP components gets lot easier and is SOA compliant as well.

Hi,

In real life Scenario there are implementations that use say only SAP CRM which need to be integrated with Legacy systems.

It all depends to the level of Non SAP Exposure your implementation has.If the NOn SAP coponents are very few then even CRM middleware would do albeit you need to code & customize it but it saves lot on end cost.

However in a complex scenario as emntioned by you it would be advisable to integrate using XI where not just the current implementation but even further scaling up based on SOA can be provided in future hence a more easily maintenable one.

hi,

if you only use CRM middleware you will need to

do lots of programming in CRM to make sure the input or output

data format is correct

if you use XI on the other hand can use standard CRM output (or input)

IDOCs etc and just map it to (or from) xml inside XI - which is relatively easier

and less time consuming that doing it inside CRM I believe
