Eva gives good advice. In addition, this is an FAQ.

see -help duplicates-.
Type -duplicates report dyad_id year- to see how many observations are
affected. Also note the -tag- suboption of -duplicates-.

> I have panel data. I am trying to run some graphs, but I set the data
(tsset dyad_id year, yearly) I get the following error "repeated time
values within panel". I do not believe the same year is repeated within
the same panel. However, in case it is, is there anyways that I can
identify the repeated values, other than manually. My database has over
400,000 observation.
