The idea to improve SAS Software is to implement the function that allows using user-defined format in splits in Decision Tree. It will be really helpful. Often the labels on the splits have limited space and there is no option to use dates or user-defined format.
I know that there is an option to duplicate column in DB and then apply the format but when you have a really big table but it takes a lot of space. The simple solution will be to prepare for users this functionality that allows applying user defined format in EM.
