Hi,
maybe generate attributes with
length(str([attribute]))
?

Hello @halaalrobassy,Please find attached the process. It's pretty simple:
You need to make sure your numbers are polynominal. Then with the Generate Attributes operator you can create an attribute named Length of ID, which is almost the same thing that Herr @mschmitz suggested (but I prefer to make it easier).All the best,Rod.6 -

Hi @halaalrobassy,The shortest way is to use Generate Attributes with the function cut().The syntax is explained within the Operator (see attached screenshot).Of course you can also achieve this in other ways as well (e.g. copy the Attribute and use Replace to only keep the relevant numbers of each "divisions" using a regular expression.Happy Mining,Edin5
