I have a dataset as follows:
hhid  psid  year
1     1     1989
1     1     1991
1     1     1993
1     1     2000
1     2     1989
1     2     1991
1     2     1993
1     2     2000
2     1     1989
2     1     1991
2     1     1993
2     1     2000
...   ...   ...

hhid=household ID
psid=personal ID within a household
And my question is how to create a personal ID (say
uid) applied to the whold panel dataset.
------------------------------------------
 
You could:
 
   sort hhid psid year
   egen uid=group(hhid psid)
 
Hope this helps
