Can not pick just a single field for "No data check", just the whole channel. Is there any way to change?

Use MATLAB Analysis app (thingSpeakRead, isnan) and timeControl (to trigger the analysis) to check each field independently, and then send a message via alerts service and you can include the information on which field is missing data.

Thanks for the guidance. Is there any example available?
Or would it be possible to add in Condition Type "No data check" a condition "field" like in Condition Type "Numeric"? Would be great!

Here is an example for triggering an alert, but you will have to modify it to be a now data check. you can also use the MATLAB visualizations code to perform the kind of data type check you are looking for.
