@victor_palacios I now have been wondering for some time how these PMML combinations might work out. I do understand it in theory and there seems to be only one short example on the hub by @AlexanderFillbrunn.
Unfortunately once I started to try and use it in a slightly more complicated manner and especially store and read the PMML models back into KNIME the whole thing seems to fail. It might be small details that are not entirely have been worked out (dropping columns, renaming them …) - but the result it: this PMML combination and compiling does not seem to work in a nearly real life environment.
Maybe I am missing something:
And well yes I have tried several things. Reverting the order of the PMML input and so on
