When you generate a VGUI record bean alone, the build descriptor option msgTablePrefix specifies the message-table prefix that is stored in the VGUI record bean. When combined with an NLS code, that prefix determines the name of the DataTable that is the source of runtime messages. For details on the NLS code, see the topic for build descriptor option targetNLS.
When you generate a VGUI record bean along with a VGWebTransaction program, the value of the build descriptor option has no effect. Instead, the value of the program property msgTablePrefix determines what is stored in the VGUI record bean.
The value of msgTablePrefix has no effect on DataTable generation.
