Basically, the requirement is to display the text in an ALV cell and the text can have a maximum length of 255 characters. Instead of scrolling down and reading the text inside the ALV cell, the requirement is to wrap the entire long text inside the cell in such a way that cell size is increased vertically so that the user can be able to read the whole long text at a time without scrolling down.

You may search the forum/SAP Web site with your favorite Web search engine. I see many answers for search below. Based on the results, if it still doesn't solve, you may anyway refine your query/provide more information.

The answers explain that it's not possible to do what you ask (ALV grid limitation), but propose several workarounds.
NB: ALV grid cell limit is 128 characters, not 255.
