Polling a webservice from XI

[Former Member]

Is it possible to frequently poll a webservice to trigger SAP jobs?

I want to configure XI to poll a webservice, e.g. every 5 seconds, and generate some IDOCs out of the returned data. Usually the information is pushed into the SAP system but this webservice simply provides the information, it is passive.

Is such a scenario possible and how?

Thanks

Hi,

XI cannt poll data from webservice. There is no such facility for SOAP adapter.

Instead change your scenario as follows.

File>Webservice>IDOC

File Adapter channel should poll some dummy data which has nothing to do with your scenario. Set Processing mode to "Test". Give polling interval according to your requirement.

And in the mapping from File to Webservice hardcode the values for your Webservice request structure.

But the only drawback is you need to do this scenario in BPM as receiver is IDOC and IDOC cannt haveEJB modules(e.g., request and response beans) as it runs on ABAP stack.

No. XI cant poll a webservice. As such it doesnt seem to be much logical.

but this webservice simply provides the information, it is passive.

At sender usually the webservice does not reside. Rather a soap client is present at sender which sends the data to XI. Now for ur requirement u should schedule the posting of data from SOAP client.

Sorry but I don't understand these threads. They all use JDBC but I want to use a webservice. What's the relation between JDBC (database) and the webservice I want to poll?

I simply want to call a webservice to retrieve e.g. the prices of banana and if the price is below x I want to issue an order in the SAP system. This sounds like an hello world example for webservice usage to me and I see no database in this example.

Hi,

Write an ABAP program that is scheduled at your required interval to initiate the Web Service request via PI and process the response from the Web Service via PI back to SAP.

ABAP program calls synchronous ABAP proxy <-> PI <-> SOAP adapter then processes the response by create IDOCS.

The whole process can be synchronous - it is pretty easy.

Cheers

Colin.
