RFC to WS. Problem with xml data structure

HI guys,

I'm working in PI 7.1 and I have developed an interface that converts xml to a string in a scenario of RFC to WS. In the development environment (PI DEV) I used the function "Return as XML" and it works fine and I had no problems.

The problem is in the QA environment: The xml structure is shifted and when it impacts the WS, it returns incorrect data.

These are the xml of DEV and QA environments:

XML PI DEV (correct):

XML PI QA (wrong):

Notes:

• I checked the versions of the RFC in both environments and are the same.
• I estimate that the problem is related to the QA adapter engine.
• The structure show in the images are before the mapping.

Does anyone have any idea to solve this problem?

Regards.

Martin
