Hi:
Your EG 4.3 may be talking to a version of SAS that was "before" SPANROWS was introduced. I can't remember exactly when SPANROWS came out -- but I think it was SAS 9.2. So if your EG 4.3 is "talking" to SAS 9.0 or 9.1, then SPANROWS will not work until your SAS is upgraded to at least version 9.2.
