I was perusing the OD log and saw the variables how the variables made it to OD: odSubstr_targetNode instead of targetNode:KEYVALUES=area=/iwmnt/default/main/Config/WORKAREA/Configfilelist=/tmp/deploytask-filelist-8653047669692578647.txtodSubst_targetArea=/usr/InterwovenodSubst_targetNode=MyLocalHostConsidering how much time I wasted on that, I was rather ****. Highly unlikely this is documented.
Have you contacted support about this - sounds like a bug as opposed to an undocumented intended change.
