Any idea why after importing, the code column is not populating even with the formular
Or does it have to be manually inserted, I realized this activity is preventing me from completing activity 220.127.116.11.
I think the issue is with your country flat list used in the formula.
There must be a hierarchical list of country present in the system, which I believe, ideally should be used as a dimension in this SYS06 module.
So you have a hierarchical list as a dimension in SYS06 and you should pull values from that hierarchical list only.
