求教各位大神TAT...快急哭了

一共只有500多行数据，要count distinct的数据是数字数据，长度不超过8。就是没办法运行，显示的错误是如下：

ERROR: Index TEMPINDX cannot be created on file WORK.'SASTMP-000001217'n because the length of the index value (12016 bytes) is too
       large. The index page size (currently 32767) must be large enough to store three index values plus a small overhead
       structure. Reduce the length of the index value or use the IBUFSIZE= option to increase the index page size (up to a maximum
       of 32,767 bytes).
ERROR: :Unable to create temporary index while processing summary functions.
