XSD nillable element

[Tomasz_Sawczuk]

Hi All

Yesterday i found out some restrictions about nillable elements is XSD definition.

Is it really impossible to have nil="true" values in messages?

Some ideas?

[Tomasz_Sawczuk]

Hi,

I have some services on Oracle Application Server. All element contain nillable="true".

With string there is no problem, we can send and empty element in SOAP message. Problems occurs with all numeric types (int, float...) and dates.

Best Regards,

When you really need the xsi:nil="true" attribute, you can create a sample SOAP request message without SOAP envelope and upload this to your graphical mapping tool as target message.

Here an example xml:

<ns0:BookingOrders xmlns:ns0="http://sap.com/xi/rkt/CaseStudy/group99"
                   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
	<Order>
		<BookingCode>2KY34R</BookingCode>
		<Passenger>
			<Name xsi:nil="true"></Name>
			<Address>123 Main St.</Address>
		</Passenger>
	</Order>
</ns0:BookingOrders>

Check out if it would be sufficient just to omit the elemts which have no values or provide initial values like 0 for float and int.

if i receive message from system A with <NETTO /> it should be send to system B with <NETTO xsi:nil="true"></NETTO>

If i receive message from system A with <NETTO>100.4563</NETTO> it should be send to system B with <NETTO>100.4563</NETTO>

How I can do it with graphical mapping tool (set tag attributes conditionally..)

JAVA/ABAP coding in mapping is not an solution it is work around...

Do it like I told you, upload a sample xml as target.

The attributes appear as individual entries below the corresponding elements. You can use the ifWithoutElse function. Map the constant true.

You said with string it works with an empty element, so why you cannot send <NETTO>0</NETTO> ?

0 is not NULL

For example ROI, IRR, etc..

Thanx for advice.

What's IRR?

[Tomasz_Sawczuk]

IRR (ang. Internal Rate of Return)

Hi Tomasz,

For which scenario do you need a nil element?
