Diagnosis
You want to change the visualized length of a screen element of typeinput/output field.
Reducing the visualized length results in a narrower field area inwhich rolling is possible at runtime in the maximum length of theinput/output field.
If the screen element does not have the attribute "with icon", themaximum runtime length is identical to the defined length.
The value you defined, however, is larger than the maximum length ofthe input/output field at runtime. Rolling is therefore not possible.
If the output field has the attribute "with icon", the defined lengthmust be large enough to be able to hold the internal representation ofa field with icon and possibly with a separate quick info at runtime.The visualized length can (and usually is) much smaller because atruntime the screen does not have spearate space for the quick info.
The value you defined for the visualized length, however, is so largecompared to the defined length that it cannot be fully used at runtime.

System Response
The system does not use the value for the visualized length.

Procedure
Use a value from the value range suggested in the error message.
