st: panel data: drop a whole group/identifier

Dear all,
I sorted my panel data by year (2004-2006) and identifier. Now, I want to drop the identifier for the whole panel (2004-2006) if a certain condition let's say for one of the years (2006) is not fulfilled. What is the correct command for dropping whole groups (characterised by a specific identifier)? I already tried the "by" command but think that this doesn't help to drop a whole group. "By" would only drop the year where the condition is not fulfilled and the remaining identifier-year observations are kept. Am I right?
Best regards, Sabrina
