I am not quite sure what the objective is, but the group function with -egen- would generate a new id based on the order of the old id.
Egen newid=group(id)

Subject: st: Transforming Unique IDs
Greetings,
I am working with a large panel data set and I need to transform the
current unique IDs into a new set of unique IDs while maintaining the
panel nature of the data. For example,
Year 1 ID1 Var 1 Var2 Var3 NewID1
Year 2 ID1 Var 1 Var2 Var3 NewID1
Year 3 ID1 Var 1 Var2 Var3 NewID1
Year 1 ID2 Var 1 Var2 Var3 NewID2
Year 2 ID2 Var 1 Var2 Var3 NewID2
Year 3 ID2 Var 1 Var2 Var3 NewID2
Year 1 ID3 Var 1 Var2 Var3 NewID3
Year 2 ID3 Var 1 Var2 Var3 NewID3
Year 3 ID3 Var 1 Var2 Var3 NewID3
does anyone have a algorithm to produce a new set of unique IDs while
maintaining the panel function? I have looked through the current FAQs
and past listserv discussions and have not found any suggestions that
would create a new ID while maintaining the panel groupings.
Thank you,
