Toolbar Button DisplayLogic

[Christophe CapBarthodia]

Hi all

I don't understand how the settings works in the ToolBar button window.
For example: I want to set the Window - Print button to DisplayLogic = @IsPrinted@='Y'.
To access it, I have to check IsCustomization, and if I set my DisplayLogic, it doesn't work.
I also tried @AD_Table_ID@=318.
Is an Action Class Name required, or am I missing something?
I thought the DisplayLogic would work as long as I entered it.

I couldn't find anything that would let me know what to do.

Thank you for your help

Christophe
