Hierarchical report - Use of ALV Tree

Hello everybody,

I have to define a hierarchical report with three level of information (header data, item data and pricing date). For this report, my technical consultant has chosen using the function RS_TREE_CONSTRUCT.

This report is now ready and works correctly. But we have a little problem. Indeed, in item data, user would like having an item text which can have on average 150 characters.

The problem is that it seems we can't display more than 70 characters. I have heard that we can have the entire text by double clicking on the field or by clicking on a specific button ? Do you know if it's possible ? Can you tell me how to do it?

Thanks a lot

Vincent
