Optional XML fields in Simple transformations (ST)

JackGraus — Mon, 12 Jul 2010 15:57:29 GMT

Hi, I am using Simple Transformation (ST) to convert an XML file into ABAP data. In my XML file some XML tags are optional: sometimes they are available in the file, sometimes they are not. I can not find out how to define a ST for this.

Either the XML fields are in the ST definition and then these field should also be in the XML file or

the XML fields are not in the ST definition and then these fields are not allowed in the XML.

Regards jack

Hi Jack, please find some sample coding below that will solve your issue:

<tt:cond check="not-initial(ref('E1EDL20.INCO1'))">
  <INCO1 tt:value-ref="E1EDL20.INCO1"/>
</tt:cond>

With the simple transformation tt cond statment you can make an XML tag optional. In below example during deserialisation xml tag <INCO1> will be skipped when not availabke in the xml and SAP data E1EDL20.INCO1 will not be filled by the transformation.

Regards. Please give points when usefull !
