Usage Note 11391: DATA Step HASH object does not support duplicate key values
Prior to SAS 9.2, the DATA Step HASH object does not support duplicate key
values. When the ADD method is used to add a duplicate key value to
the hash table, a non-zero return code is generated. If the DATASET
argument is used on the DECLARE statement and the data set contains
duplicate key values, the data from the first occurrence of the
duplicate key value is added to the hash table. Subsequent data
values of the duplicate key are not added. No WARNING or ERROR
messages are generated when the are duplicate key values are
discarded.
Beginning in SAS 9.2, duplicates are supported with the MULTIDATA:'YES' initialization parameter. For more information, please refer to the SAS 9.2 Language Reference, Dictionary documentation for the DECLARE Statement.
