Hi Guys, I was actually looking into the message mapping blog of sravya.Link below: http://www.sdn.sap.com/irj/scn/weblogs;jsessionid=(J2EE3414800)ID0086183650DB11663053995735659636End?blog=/pub/wlg/2792 Was just reading the blog and a lot of questions came through my mind.In the end I figured out that first, I have to understand how the parsing works. So for example,If we have 2 message structures(source & target).At run time the dom or sax parser parses through the source xml document. If we do a source to target mapping as in the example Matgroup --> RemoveContext -->MatGroup. So my question is what does the parser do in the above example. Does it read the source xml,change the source XML AND start to build the target xml from scratch by adding nodes. How does the parsing work & internally what are the steps the parser do to create the target XML. [2] In her example,She mapps the item node to the header target node. what happends then or what does the parser do & what are the elements which will be coming under the target header node. What are the conditions for mapping 2 fields or nodes(Both should have same level & occurance - Is that so?) Iam confused.Please Enlighten me...:) Thanks P Hi Guys, I was actually looking into the message mapping blog of sravya.Link below: http://www.sdn.sap.com/irj/scn/weblogs;jsessionid=(J2EE3414800)ID0086183650DB11663053995735659636End?blog=/pub/wlg/2792 Was just reading the blog and a lot of questions came through my mind.In the end I figured out that first, I have to understand how the parsing works.
