When you enter a web address for the initial screen in the browser, if the web address exceeds the maximum 2048 characters allowed, the following error message appears, "Unable to open the requested display. The web address exceeds the maximum length of 2048 characters".
Different browsers have different length limits. If you get this error message because you are using large numbers of parameters it is recommended that you use a parameter file instead.
To avoid this problem, rework the screen so that the web address is less than 2048 characters.
