As you may already know SAP keeps track of table content changes if you switch on ‘Log Data Changes’ option in table technical settings. Here you can see how to activate this small but effective checkbox for database tables.
There are cases where the users want to see XML data in SAP screen. For this aim SAP has provided a couple of function modules under SDIXML . I have used SDIXML_XML_TO_DOM and SDIXML_DOM_TO_SCREEN in my sample.Because I had an internal table that can be converted to XML format as described in convert ABAP internal table to XML format post. And finally i wanted to show this XML in screen.
