As far as I understand is there a problem with the XPATH expression.

Channel → State Transformation

XPATH:/Devices/Device/HEATAREA[@nr='2']/T_ACTUAL/text()

Item → XPath Expression

/*[name()='Devices']/*[name()='Device']/*[name()='HEATAREA']/*[name()='T_ACTUAL']/text()

I would aprichiate if somebody can help me!

Thank you.

That error message comes from a profile, a modifier you chose to apply to a channel-to-Item link.
If you’re doing your transformation in the channel then you do not usually want to do another with a profile. You certainly don’t want to apply XPATH if you’ve already done that in the channel.
