Can I found out wether or not a Transaction has a Gui ?

Hello Everybody,

I have actually one question.

I need to know when I'm executing a Transaction to know wether or not this transaction has a GUI.

Well, I think this's possible but what I don't know is, if there's mechanism where I can ask the SAP-System but the mean of table if this Transaction has a GUI.

Thanks for your help.

I'll appreciate that, if you can give me some tips.

Best regards,

Kais
