What is the advantage to generate XML via XI than from ERP using XSLT

Hi experts,

My requirement is to generate XML file from ERP when the production order is closed. I can do 2 things:

1. batch job in ERP to read all data and call XSLT to generate XML

2. batch job to generate LOIPRO01 IDOC, which will be taken by XI and XI makes XML

Which solution is better and why?

Please support me.

Thanks a lot.

Kind regards,
