Suggestion:
System has provision in Generalised master to add pophelp values in any field as per the screens requirements.
Generalised master menu exists in SCM ->SCM Setup-> Master-> Generalised master.
The User has to select the field name for which value needs to be added, then the user has to select the mod name which is the screen name (win name) and enter the value and its description. This setting can be done by only by the Proteus Team.
