PI 7.30: SOAP Axis Sender Adapter - avoid polling when no file to poll

Dear experts,

I have set up a SOAP Axis Adapter and under "Connection Parameters" I set "Interval (msec)" to 120000, so every 2 minutes the adapter connects to the http-address to poll files. Now if there is no message to poll I get an empty message in SXMB_MONI with a red flag. That is annoying.

So now in the "Receiver Determination" I put in a conditon checking if the message is empty or not:

Now all I get in SXMB_MONI is a message that says (no red flag anymore):

But is there a possibility that the AXIS Sender Adapter does not create a message at all? Am I missing a certain setting here?

Thank you for your help and best regards,

Peter
