Inbound Invoice IDOC mapping Required fields

Hi All,

Please let me know what need to be mapped for the @begin , @segment , TABNAM , SNDPOR, SNDPRT etc like this elements in the IDOC structure.

In my scenarion i get Invoices in XML file so that i can pick that and process it into SAP R/3 by doing correct mapping with the inbound IDOC and post the same into R/3 . Please provide the sample mapping for processing Invoice IDOC.

Regards,

Reddy
