RFC -> XI -> WebService - Walkthrough ----Importing WSDL, problem

[Former Member]

Hi

I am following this weblog

/people/shabarish.vijayakumar/blog/2006/03/23/rfc--xi--webservice--a-complete-walkthrough-part-1

I have createed RFC as mentioned in this blog

<b>BLOG-----RFC</b>

-

---

Import :

FROMZIP type CHAR10

TOZIP type CHAR10

Export:

DISTANCE type CHAR10

source code:

FUNCTION Z_WEBSERVICE_TEST_SHABZ.

*"----

---

""Local interface:

*" IMPORTING

*" VALUE(FROMZIP) TYPE CHAR10

*" VALUE(TOZIP) TYPE CHAR10

*" EXPORTING

*" VALUE(DISTANCE) TYPE CHAR10

*"----

---

ENDFUNCTION.

<b>My RFC</b>

-

---

Import :

FROMZIP type CHAR10

TOZIP type CHAR10

Export:

DISTANCE type CHAR10

source code:

FUNCTION Zdushanth_webservice.

*"----

---

""Local interface:

*" IMPORTING

*" <b>REFERENCE</b>(FROMZIP) TYPE CHAR10

*" <b>REFERENCE</b>(TOZIP) TYPE CHAR10

*" EXPORTING

*" <b>REFERENCE</b>(DISTANCE) TYPE CHAR10

*"----

---

ENDFUNCTION.

when I activate I am getting as Reference parameters are not allowed with RFC ?

I have created by referring this blog but in the source code (Importing and exporting) I am getting REFERENCE ?

why I am getting this ?

Thanks

Dushanth,

Change all parameters i.e. import / export / changing in your RFC function module to pass by value. I mean there is a checkbox "Pass value" for every import/export/changing parameter.. Check this checkbox.

RFC always expect values to be pass by values...not by reference.

Hi,

As Nilesh wrote, while trying access <i>RFC-enabled function module</i> you have to

pass parameters by value not by reference.

Hi,

Thanks Jakub and Nilesh for your replies.

I have imported RFC in XI. I have imported .wsdl file also in external definitions but when I click on the WSDL tab, it gives me the following error

"Unable to convert imported document to WSDL

Reason: Error when parsing the XML document (Fatal Error: com.sap.engine.lib.xml.parser.ParserException: XML Declaration not allowed here.(:main:, row:1, col:8))

Check the selected category "
