The SASEXCCM engine should be used instead of the SASECRSP engine for accessing the CCM database (SETID=250). The SASEXCCM interface engine is now production for CCM, STK, and IND access. The TRS access is an experimental feature and should be used at your own risk. CRSP supplies SAS data sets for US Treasury data in its TFZ product. The SASEXCCM interface engine supports Linux X64 (LAX), Solaris X64 (SAX), Solaris SPARC (S64), and Windows.
