Hi Waleds:
Regarding XML-EDI mapping,just its a simple process.Before starting your mapping to EDI you need to have X12 4010 820 template file(which helps finally creating edi 820 document using this value referencing) and 820 Schema file (which loads and creates the record structure in webMethods)using the Developer tool.Finally you can start mapping xml to edi according to your requirement.
Templates and Schemas has to be downloaded from Advantage website.
Regarding mapping you are right its segment/field mapping methodology,this depends on your requirement how many segments you want to populate.
And I believe you already have XML record structure loaded in wM …
Thanks.
