This message will appear when a scrolling input function is invoked that has multiple image specifications defined and the display only (Dspl Only?) checkbox is set to “no” on an image prior to the scrolling image. Within a Frame, all the images defined before a scrolling image must be display only.
Note; if a modifiable field is specified on an image that is defined as display only, APPX will automatically set the Dspl Only? flag to “no” when the image is saved. You can reset the flag to “yes” if your application requires a modifiable field on the image. Refer to Chapter 3-6 of the Application Design Manual for further information on the Dspl Only? specification.
