"[SOLVED] Join - Cannot map another string for binary attribute: already mapped s"

Hi All,

I'm trying to use the Join operator to do a look up data from the left input against a table at the right input - a "vlookup" in Excel - sorry, my IT skills are shocking.
It works for the first few key attributes but then as soon as there are multiple values in the "left key attributes" it gives this bug "Cannot map another string for binary attribute: already mapped two strings"

Any ideas how to achieve this with different operators?

Thanks in advance.

    in your ReadExcel operator settings you have defined most attributes as "binominal". That means they can only contain two values: value1 or value2. If they are asked to add any other value the process will fail. To change that for attributes which will consist of more than 2 different strings, select your "ReadExcel" operator, click on the "Edit List" button for the "data set meta data information" parameter and change the type via the dropdown menu in the second to last column for each affected attribute from "binominal" to "polynominal".

    Thanks for that. Solved.
    The binomial values were not correct.
    I was also trying to map too many columns to each other - I just did reoccurring Join operators in the end and it seems to be working....
