Check this option to indicate to RAMP-TS that the SHARED Object file is to be retrieved from the nominated Private Definition/aXes Project Folder.
A RAMP-TS session's SHARED script object is defined in the script file UF_SY420_RTS.JS and by default resides in folder \aXes\ts\skins, which means it is common to all RAMP sessions within the Axes instance.
If you check this option you are indicating that you will use a private version of this file and the SHARED Object will only apply to this particular RAMP-TS session. You will need to copy the file to your private definition folder.
This also means the SHARED object file will reside in folder \aXes\ts\screens\<your private definition/axes project folder>.
This property is in the Server Details tab.
