Hi Alan, Thank you for your fast reply.
To change the way Reaction_Enumerator matches the elements of incoming lists, click on Reaction_Enumerator and then the Details tab of the bottom left window. You will see List Handling as one of the possibilities there. Click the plus sign against List handling and you will almost certainly see that it is set to do Cross product. Press the Configure button. In the pop up window, select the node that says Cross product. At the top right (sometimes not completely visible) there is a button that says "Change to Dot Product". Click that button and you should see the node change to say "Dot product". Click OK.
If I change it to the dot product I get an error. Have a look at the picture.

It seems that every outgoing data is multiplied with each other (You can see it at the attached pictures. 2 (iterations) ^ 3 (ports) = 8). Is there any possibility to prevent that behaviour?Yes. It looks as if you are doing a cross product on the inputs of Reaction_Enumerator. i.e. each of the two leaves of Reactant_2 is matched with each of the two leaves of Reactant_1 and with each of the two leaves of Reaction. That gives 2 * 2 * 2 i.e. 8 combinations. You probably want to change to using a dot product. Then the first leaf of Reactant_2 is matched with the first leaf of Reactant_1 and the first leaf of Reaction, and also all the second leaves are matched. That will give just 2 combinations.

When you now run your workflow you should only get 2 iterations of Reaction_Enumerator.Cheers, AndreasAlan ------------------------------------------------------------------------------ Virtualization is moving to the mainstream and overtaking non-virtualized environment for deploying applications.
