So how do you produce an example XML payload for the inbound (and outbound idocs). You would think this would be a standard bit of functionality, click a button and out comes the XML which you can pass to mulesoft or whatever other middlewear you are workinbg with.. Well its not.


There are several methods, you can use standard program RCOD_DOWNLOAD_IDOC_AS_XML in newer systems. You can also use function module IDOC_XML_TRANSFORM but this add extra spaces to the close tag and just displays the data on screen, so is not easy to get if from there to a file.

Honestly the best way is to use a custom program like below which is basically a simply version of RCOD_DOWNLOAD_IDOC_AS_XML.

But even this does not get you a file that is correct to just send out, as the idoc contains adtional data that has been added post processing like IDOC number etc which is not relevant for the external system. It doesn't need this to send and doesn't get this sent back to it as IDoc communication is asyncronous.

Manipulate the XML file

So once you have produced the XML file using whatever method you you have to remove sections you don't required. The easiest way to do this is to use the exclipse editor.

Simply open up the file in eclipse




and you should see somthing like this




first step remove all the entries that contain data that wasn't part of the initial trigger data i.e. entries containing EDI_DS. to do this right click and select delete




Now check the initail section, you will see enteies for IDoc number, basically remove down to IDOCTYPE




So you end up with something like this
