How To Fix AQV255 - List is wider than 255 characters (generation not possible)

SAP Error Message - Details

• 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)

What causes this issue?

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.

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 statistics or ranking lists are responsible for the list
being too wide. Change them so that a line width of 255 characters is
sufficient.

• What is the cause and solution for SAP error message AQV255 - List is wider than 255 characters (generation not possible) ?

  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 the lengths of the fields you are trying to include in the list. Ensure that the total width does not exceed 255 characters.
  Modify Data Structure: If you are using a custom data structure, consider breaking it down into smaller components or reducing the number of fields included in the output.
  Use Sub-Lists: If the data is too wide, consider generating sub-lists or paginating the output to fit within the character limit.
  Adjust Output Format: If applicable, adjust the output format to reduce the width. This may involve changing the way data is displayed or formatted.
  Check for Concatenation: If you are concatenating strings or fields, ensure that the resulting string does not exceed the limit. You may need to truncate or format the output differently.
  
  Related Information:
  
  ABAP Programming: Understanding how to define and manipulate data structures in ABAP can help prevent this error. Familiarize yourself with data types and their lengths.
  SAP Notes: Check SAP Notes for any specific patches or updates related to this error message, as there may be known issues or enhancements that address it.
  Documentation: Review SAP documentation regarding list generation and output formatting to understand the limitations and best practices.
  
  By addressing the character width issue in your report or list generation logic, you should be able to resolve the AQV255 error.
