Some procedure options assume a definite data order for a proper execution of the intended statistical analysis. For example, the ORDER=DATA option is not compatible with input CAS tables because the order of observations in a CAS table is not fixed. Attempting to use such an incompatible option would result in an error. To avoid the error, you must input a SAS data set instead.
For more information about incompatible options in various procedures, see the section Options Incompatible with Input CAS Tables of Appendix C, Known Issues in Using CAS Tables with SAS/STAT Procedures.
