The original question appears a bit vague
1. "the order in any display for SAS EM" : what does this mean? Does this mean under Edit Variable 'meta data' layer or elsewhere?
2. "in the orginal data set": if you are referring to the original input data set, the chance it will never be displayed the same as one moves along the EM flow. You mean the data set right before the node in action? I suspect you are talking when you input the data set into EM, you already have spent time settling the meta data, roles, types,... you don't want EM to act on it, to twist, to turn.. in ways that you (frankly speaking most people) don't know. If this is the case, it is first of all not a display issue, right? Please clarify.
