5. If the output from Dispatch or Reselect shows that inbound data and outbound
data sometimes vary in their format, you might need to use formatters to do data
conversions. See “Converting Data Representations,” later in this module, for a
discussion of this topic.
6. Validate the IDoc mapping against the SAP schema for the IDoc, as described
below.
Validating an IDoc mapping
A client can use an XML Schema file to verify that a given XML document is valid. In
some cases, a document generated by the Director will fail validation because data
elements are missing or are not in the expected order. Because the content of an XML
document generated by the Director depends on the order in which the format metadata
defines the elements, you can usually solve a validation problem by changing the order of
metadata statements.
To validate an XML IDoc mapping against the SAP schema for the IDoc, follow these
steps:
1. Obtain IDoc XML schemas from the SAP website. Save each schema as an .XSD
file.
2. Generate a sample XML IDoc file with the Director. Use the Reselect or
Dispatch stand-alone program. See “Testing the Metadata” for more details.
3. Open the XML IDoc file with XML Spy. View the file in “Schema/WSDL
Design view” mode.
4. Assign the schema obtained from step 1 to this XML document. From XML Spy
main menu, select DTD/Schema -> Assign Schema… to assign the schema.
5. Validate the XML file. From XML Spy main menu, select “XML -> Validate” to
validate the file.
6. If there are error messages, they will suggest how to modify the metadata. For
example, the current format metadata may generate the output file with the XML
sequences in the wrong order. In that case, you need to rearrange the metadata in
the order defined by the XML Schema to pass the validation. Modify the format
metadata as needed.
7. Compile the Java source file and repeat steps 2 to 6 until the XML IDoc passes
the XML Schema validation. See “Compiling Metadata” for compilation steps.
8. Deploy the updated Java class file to the RTID runtime environment. See
“Deploying Metadata” for deployment steps.
