XI 3.0 SP22 - Mapping Designer: Duplicate Subtree bug

Hi,

I've found an issue on one of our client XI systems when using the Duplicate Subtree function in the Mapping Designer for an imported IDoc message. The problem is that when a segment or field is duplicated it does not appear directly after the original segment/field... This would be fine in a structure where the order is not important, but in an IDoc it is causing the message to fail when the syntax is checked. I have never encountered this issue in any of the systems I have used before... A quick unrealistic example....

I want to duplicate the E1EDK01 segment...

Original Structure...

EDI_DC40

E1EDK01

E1EDK14

E1J3K03

After Duplicating the E1EDK01 node...

EDI_DC40

E1EDK01

E1EDK14

E1EDK01

E1J3K03

What I was expecting...

EDI_DC40

E1EDK01

E1EDK01

E1EDK14

E1J3K03

If anyone has come across this issue and resolved it, please let me know...

Thanks,

Pete
