SUMMARY:
In Strategy 10.x, users may notice that the options for the Java Connector Version are greyed out for MDX Database Instances that connect to SAP BW.

CAUSE:
This behavior is by design. In Strategy 10.x, the JVM which is used does not support JCo 2.x.
ACTION:
Update any Database Instances that are using JCO 2.x to use JCO 3.x. For more information on updating your MDX database instances, see KB249462.
The Strategy Internal Reference Number for the issue discussed in this technical note is DE8791.
