Can I create a "UPSERT" Service which calls 2 services without using BPM ??

Question

Hi all,
I'm on PI 7.10 and have the following problem.
I want to Upsert (Update or Insert) an Account into a 3rd Party System.
The third party system does not have one web service that does this, instead it has
Update -> Will update an existing account (but will not create it if it's not there)
Create -> Will create a new account (but will not update it if it is there).
I have created a generic Service Interface (abstract, synchronous).
I have created two operation mappings (create, update).
I want to
Call the update service
If it succeeds
  respond with success
Else (if it fails)
   Call create service
   If it succeeds
      respond with success
   else
    respond with failure.
I ideally want to do this without using a BPM and was thinking there may be a way to call multiple operations sequentially.
Can you do this by
Mutliple operation in the Service Interface?
Multiple operations in the Operation Mapping?
Is there another way without using a BPM?
Ideally I'm looking for a link to an article or help documentation describing how to do this.
Thanks in advance for your help.
Regards,
John

Answer 1

I think BPM will be required in this case.
Your requirement is to perform Insert OR Update.....insert and update actions depending on result of each other.
first send a Insert request to the target system and get back the response...depending on the response decide if the record was inserted or if there is a record already present and if present then send a Update request from the BPM.
Check how your webservice responds back....you mentioned that SUccess or Failure is to be communicated....from where should this be send...is the WS sending it or should PI send it?
Other way would be to make use SOAP lookup and perform valiudation in Mapping based on response of the lookup.
I am doubtful if Multiple Operations will help you in getting this requirement done.
