XML Optional node

Former Member — Wed, 24 Nov 2010 09:36:02 GMT

In the below XML code how to make the <CUSTOMERDETAILS> node as Optional node.

If suppose in the input XML file if <CUSTOMERDETAILS> node is not available,I want to make the node as optional one.

As of now system is getting dump, becuase node data <CUSTOMERDETAILS> is not availbale in the XML file.

You might be able to solve this using conditional transformations, please see SAP online help for simple transformations:
