Message type: E = Error
Message class: AQV - Message texts for SAP Query
Message number: 255
Message text: List is wider than 255 characters (generation not possible)
You tried to define a query in which the line width of the generated
list exceeds 255 characters.
The line width is defined in the <LS>Title, Format</> screen. A maximum
value of 255 can be defined there. When you define statistics and
ranking lists, however, this value could be implicitly enlarged since
the lines of statistics and ranking lists may not be broken. This is
such a case. The implicit extension would result in a list that is
wider than 255 characters. This query therefore cannot be executed.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
Check which statistics or ranking lists are responsible for the list
being too wide. Change them so that a line width of 255 characters is
sufficient.

The SAP error message AQV255, which states "List is wider than 255 characters (generation not possible)," typically occurs when you are trying to generate a list or report that exceeds the character limit imposed by SAP for certain operations. This limit is often encountered in contexts such as ABAP reports, where the output or data structure exceeds the maximum allowable width.
Cause: Field Length Exceeded: The error is primarily caused by attempting to create a list or report that has a total width greater than 255 characters. This can happen if you are concatenating multiple fields or if the fields themselves are too wide. Data Structure Definition: The data structure defined in your ABAP program or report may have fields that, when combined, exceed the 255-character limit. Output Formatting: If you are using certain output formatting options that increase the width of the output, this can also lead to the error.
Solution: Review Field Lengths: Check
