Problem in Webservice

jitendra_it — Wed, 29 Jun 2011 10:37:35 GMT

Hi Gurus,

We are creating a webservice in ABAP using FM, which have multiple EXPORT parameters.

when java people consume it, it is showing all the paramerter as input parameters in java and return type of method(FM) is VOID.

Can't we create a FM in ABAP which have multiple export parameters and publish it as webservice??

Please help.

Thanks

Hello Jitendra soni,

Each IDE has different way of generating the Proxy. Eventhoug it appears as input parameter in the java side. You don't need to pass the value ti it during the webservice call. All the values will be populated by SAP during the webservice call and you need to take the value back from that field after the successfull completion of your webservice call.

For some IDE's due to the restriction you may need to intialize the values for some return parameters including the BAPI return parameters.

In the SAP side we need to clear all the values that are comming from the java interface call in the very first line of the FM code safer side( for all the Export and result tables parameters values).

Hope this answers your question.

Thanks,

Greetson

I totally agree with Greetson.

You can also create a ZFM which is remote enabled and publish it as a web service using ABAP.

Thanks.

Yes. You can use both Changing as well as tables. During the proxy generation corresponding classes will get generated and you need to pass the array of the class that got generated to the Webservice call for the tables .

Thanks,
