If you are using the T7 version, when it pops up the PO-B screen (automatically), you can click on print, on the "select report format name" screen you can pick whichever you choose (t6pob4.rtm?), click settings, save settings.  I think that is the way it works.

It sounds like either you have Evo Notes turned off in this company but are trying to use an "EN..." RTM or you have Evo Notes turned on and are using "T6..." RTM.  You have to use the correct RTM version for the Notes setting.

SD-Q, System Manager, there is a Configuration Settings that needs to be turned on as well as a setting for Enable Save/Change Default RTM.   From the Help file:
 
Configuration Settings
 
This setting controls whether the settings on selection screens for various forms throughout the system can be changed.  A blank or 0 means that no settings can be changed and program default settings will always be used.  A value of 1 means that a system wide set of defaults can be established but user-specific settings will not be available.  A value of 2 means that system wide defaults can be established but user specific settings can also be maintained on each workstation and will override the system settings.  The actual settings are established in the programs themselves such as SO-B  Print Acknowledgements  
 
Password
 
If the configuration settings are set to 1 or 2, this password will be necessary to make changes to the system wide configuration settings.  If the password is left blank, any user can change the system wide configuration settings.  Individual user settings at the workstation do not require the password and can be changed by each user at any time.
 
Enable Change/Save Default RTMs
 
If this  is Y then when an RTM other than the default is entered for a form or report, the user will be prompted whether they want to make that RTM the new default for that program.
