Thanks Jean....
As of today repdef supports having keywords in ASE table (SAP applications push ASE/RS to the extremes and we - non SAP users benefit from it). What you have to do is to use the keyword "quoted" in addition to wrapping the column names in quotation marks. Not very intuitive but it works. You need to configure connection to support quoted identifiers, use quoted identifiers in column names in repdef AND add "quoted" after each problematic column... That's the trick
