select attributes by aggregation [SOLVED]
Hi!
I have a set of examples with one id attribute and several regular integer attributes that contains only binary data (0 or 1).
I wish select only the regular attributes whose sum (by column) is greater than a specific value (defined in a context variable)
Which the best way to solve it (from original data, select only the regular attributes whose sum is greater than a variable value) ?
Many thanks in advance

try something like the process below. After the aggregation, the aggregated data is filtered (in this case such that the sum of att1 is smaller than -5), then joined with the original data. To understand the process, it might be helpful to define some operator breakpoints and debug through the process.
