If the DATA= and SAMPSIZE= or N= options in PROC SURVEYSELECT both
specify the same data set and that data set is indexed on a STRATA
statement variable, then a stratified sample may be incorrect. Under
these conditions, PROC SURVEYSELECT performs an operation to rewind to
the beginning of the data set instead of performing the rewind within
strata, and the resulting output data may be truncated.

To circumvent this problem, remove the index and sort the input data set
on the stratum variable(s).
