Would you plz let me know how I can remove the records with more than 3 missing values.

Thanks in advance

The "Filter Example" operator is correct, but you need to create a new attribute which counts the missings of this example before and filter for this single attribute. See the proces below for an example.
To get this count you have to use a few operators which I have collected within a subprocess called "Count missings". It is easy to get the count of non-missings, but to get the missings you have to substract the total number of attributes which you can get via the "Extract macro" operator.
Thanks for the great help!
I used the code and that was a wonderful one!
