The claimant is the best source of information about their past work. However, if
the claimant is having difficulty providing information a Detail Earnings Query (DEQY),
Summary Earnings Query (SEQY), or other query may be accessed to help you resolve
any questions.
Use of a query is not required, however, if a query is used, it must be added to the
electronic folder (EF).
For additional information on resolving insufficient vocational evidence using a DEQY
or a SEQY follow DI 22515.020B.
