Hi,   I have used "options validvarname=any;" in my EM project start up code, and everything works okay until I get to the reject inference node which is giving "not valid SAS name" error messages in the log.   Please can someone confirm if validvarname=any is not compatible with the reject inference node? If it is compatible, is there another way that you are supposed to set the option?   I have a very large number of variables with hyphens in the name and don't want to have to rename them all.   Thanks   EM version = 14.3   Edit:   Error message (I've tried completely dropping and renaming the variables from the data node but still get the error):   NOTE: CALL EXECUTE generated line. 1     +   data EMWS1.RejInf_SCOREREJECTS; 2     +      set EMWS1.Ids_DATA; 3     +      %include _F1; NOTE: %INCLUDE (level 1) file _F1 is file [......]\PATHFLOWCODE.sas. 18111 +*------------------------------------------------------------*; 18112 +* TOOL: Input Data Source; 18113 +* TYPE: SAMPLE; 18114 +* NODE: Ids2; 18115 +*------------------------------------------------------------*; 18116 +drop Day; 18117 +drop 'Example-1-External-Variable'n;             -----------------------             24 ERROR 24-322: Variable name is not valid. ...
