XML File Generation

Hi Abap Experts:

I need to create a XML file from the structure ls_bil_invoice (type lbbil_invoice).

This structure is used in the stadard program RLB_INVOICE, the one used for invoice printing.

Anyway, with the data provided in this structure I need to create a XML file.

Does anyone know how to do it?

Thanks in advance.

Best Regards.

Eduardo.
