Business Service "OPA Interview Framework Service" and Method "ConvertSiebelIntObjToGetAnswerReqIntObj"

2) In the middle Applet, load an EAI-Siebel-Adapter-Output-Argument file containing empty tags.

3) Run

4) Save the output to file nad notice the empty tags are not stripped. This message contains empty XML tags.

this step you can't run, because the rulebase is for customer specific.
