How to compare 2 examples using loop in Execute Script operator?

I want to compare 2 examples in one attribute named "ID" and if they are equal then I have to compare another set of examples under another attribute named "Date". If they match, then I need to rank them with same rank starting from 1 in ascending order. If the examples do not match in "Date" attribute then I need to rank them as 1,2 & so on. How to achieve this using Execute Script operator? Please help.

    I think you can do this with a combination of Sort and Generate ID, but you may also want to check out the Sort (Advanced) from the Jackhammer extension.  The old Finance extension also has an operator for Rank, but that extension isn't being supported anymore.

    The data is already sorted but I am unable to generate the desired output. I am new to Rapid miner. It will be helpful if you can share me the process. Thanks in advance.

    Hi @Sp_Iq,
    i think there is no reason to use a script here. Attached is a process which goes into the direction you want to do.  Not sure if it is 100% what you need.

    Hi @mschmitz,

    I couldn't find the attached process. There's only 1 line in the attachment. Can you please attach it again. Thank you.
