How can I control the width of the ALV? (not the width of a specific column). The width is fixed. When there are few columns, an unnecessary space is created (see yellow). When there are many columns, the ALV cannot be increased and a scrollbar is created.

When I set attribute max_linesize of the layout it does not affect the ALV's width. (line 69).

By the way, the problem does not exist when using REUSE_ALV_LIST_DISPLAY.

Thank you in advanced

I think that you'll always see this line. The only way to reduce it is to reduce the container width to be the total width of all columns. As far as I know, SAP never did that in his own applications. I know how to approximate but it may be wrong, so need to multiply by a given factor to make sure all columns are visible. Conclusion: I think it's impossible to achieve a good result, also no interest except if you meet nitpicking people (focusing on things of no interest), so it's not worth spending time on it.

sandra.rossi Thank you for your answer.

How can I reduce/increase the container width (when using REUSE_ALV_GRID)?

[Sandra_Rossi]

Many ways. A container can be:

• Custom. Choose the size you want in the Dynpro layout.
• Docking. You may choose the width if you dock at the left or right.
• Splitter. There is a method to choose the width of two containers in a row.
• Dialog box. You indicate the dialog size.

(also Dynpro popup if it's something you can afford)
