webservices and Rollback

Hi All,

I am looking for an approach/solution to handle rollbacks in the below scenario.

We have SOA m/w that issues updates to multiple systems including Siebel. Our requirement is to roll-back the update in Siebel, if the updates in the other systems fail.

e.g: SOA issues updates to System1, System2(Siebel; currenly via inbound service calls) and Syetm3 etc.

If the update fails in one of the systems i.e. Syetem 1 or System2 , the transaction should be rolledback in Siebel.

Could you please share your thoughts on how to implement the above requirement ?

Thanks in advance,
