Hi.
Great information. Thanks.

Anyones knows where is it… I cant find it in SDN SAP web site or in SERVICE SAP web site.
Thanks in advance.

1. THERE IS a nicer way to deal with structure changes in 7.1. When you see those messages that one or another node is not found in the structure, there appears a new button on the Message-Mapping’s toolbar: Correct Structural Inconsistencies. Press it and you will be suggested to select a field from the new structure for every missing field.
2. XIM file is a zip, actually. You can unzip it and get your hands on (almost) the same mapping definition in xml format.
3. Developers buried this functionality, because the management didn’t want to get into the hassle of officially supporting it. But developers needed it for debugging purposes and for dealing with customer problems. This import/export was developed before the export to xim file, which is superior.

A way to avoid having to remap everything with PI 7.1, if you want to add messages or even just change an std idoc with a quite similar z-idoc within a multi-message mapping is :

- Create a mapping template from the mapping you have created for an appropriate level in the message(s), and then reuse the template on the new set of messages.

As Daniel says, the feature is not available in PI 7.1.
You can export the XIM file, but it will not be possible to replace text as in MTE file.
There is an option to import a JAR file but it seems to be difficult to do anything useful with the byte code.

Would be interesting to know if anyone found a way to avoid having to remap everything with PI 7.1, if you want to add messages or even just change an std idoc with a quite similar z-idoc within a multi-message mapping.

Hi,Gr88 blog but i have one doube here that why did you change occurence for both source and target in the text file when you wans to change just from 1: 1 to 1:N.From my understanding only changing target message type is enough.

I have always liked to play with the xml mappingsfiles. And this is the easy way to switch root elements.
This feature is not available in PI 7.1, but it is possible to change top level element names.
