How To Fix AQ255 - List is wider than 255 characters (generation not possible)

AQ255 - Overview

• Message type: E = Error

• Message class: AQ - Message texts for SAP Query

• Message number: 255

• Message text: List is wider than 255 characters (generation not possible)

What causes this issue?

You attempted to define a query where the line width of the generated
list is greater than 255 characters.
You define the line width on the <LS>Title, Format</> screen which
permits a maximum width of 255 characters. However, when defining
statistics and ranked lists, you can implicitly increase this value,
since the lines cannot be broken up. This is the case here. An implicit
increase in the width of the list would result in a list wider than 255
characters. For this reason, the query cannot be executed.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check which of the statistics or ranked lists is responsible and modify
it so that the resulting list width is no greater than 255 characters.
