The following error can occur when you create a compressed SAS data set from an empty hash object with the OUTPUT method:

  ERROR: An error has occurred during instance method OM_OUTPUT(505)
         of "DATASTEP.HASH".

This is a subset of the problem reported in Problem Note 17149: "OM_OUTPUT(505) error occurs creating compressed data set with OUTPUT method."

The workaround is to specify COMPRESS=NO for the duration of the DATA step.
