Cannot generate ABAP proxy

[Former Member]

Hi,

I am getting the following error message while I am trying to generate an ABAP proxy:

Cannot generate proxy (object <element name="SubstanceComponent"> missing in WSDL, see long text)

I did the following steps:

<i>1) Import an External Definition from an XSD-File:</i>

<i>2) Create a Message Interface based on the External Definition

3) Trying to generate the ABAP proxy...

</i>

Do you have any idea why the proxy generation is not working in this case? Is it the recursive use of element "SubstanceComponent" that doesn't work?

<xs:element name="SubstanceComponent">
		<xs:complexType>
			<xs:sequence minOccurs="0" maxOccurs="unbounded">
				<xs:element ref="SubstanceComponent" />
			</xs:sequence>

Thanks,

Andreas

Hi Andreas,

you CAN import external definition, but they make problems. It's easier to build the datatype, in ur case it's not much work.

Hi Udo,

thanks for your answer.

I wanted to avoid to build the datatype manually, since I have the complete description in a XML Schema.

Unfortunately the full description of the Message Interface will be much bigger. I just started with a small piece to find out if it works.

In the meanwhile, while importing the whole external definition I get the following error:

<i>"Proxy generation terminated: Recursions not supported"</i>

So it seems as if the proxy generation doesn't support the recursion at all and I have to work on the definition...

I removed the recursion... now the proxy generation works.

Yes, and there r some more restrictions.

The only useable way 4 import XSDs is to export them, change them just a little, little bit and reimport.
