问题描述不清楚，没有办法回答

是不是你导入的时候SAS里的原数据集没关啊?

I met this problem before, and still haven't found a good solution.

Anyway I got the whole data in SAS in a stupid way. I copied the new column in Excel to SAS enhanced editor to create a new data set, and then merged it into the imported data.

楼主出现的错误的提示是什么？
如果是数据集已经存在的话，后边加个replace就行。
