POS-Inbound Sales per Receipt --- Urgent

Hi All,

I need to post POS inbound XML file to Retail system, as we don’t use the middleware, also I can’t use program to convert xml file to WPUBON01 IDOC to post. Is there any Transaction-Code available in Retail? or any BAPI available for POS inbound sales per receipt to post ? please advise..

Really appreciate if anyone can help….its really urgent. Thanks.

With Regards
