i had this problem i should do with decision tree and i did this process attached (refundDT1) this was the result
and i got this :
"for which channel there are canceled orders and the associated early
detection of possible cancellation sources in the channels and process
You create a decision tree with only one descriptive variable (variant
index) and target variable "Channel". Where can you read "which channel
has canceled orders"? And where are the sources of cancellation?
As with 1), it is wrong to refer to the variant index. The variant index
is just a list of the different variants and its level has no relation
to the channel or the termination
now i made this new process (DTrefund2.rmp) and i get the same result
so what should i do and why is it using Variant index only?
