I would like to let you all know that a HOT NEWS SAP Note has been released for customers running SAP applications on SAP Sybase ASE. Please have a look at SAP Note 1926514 and act accordingly as soon as possible.
The SAP Note boils down to issues with the ODBC driver versions 184.108.40.2064 to 220.127.116.117. Running this ODBC driver versions in combination with older versions of the Sybase DBSL can lead to short dumps, fetch errors and incomplete result sets. We highly recommend to use at least ODBC 18.104.22.1688 or higher and at least DBSL 7.20 patch level 427, 7.21 patch level 129, or 7.40 patch level 19.
