Disable button in Infotype application toolbar

[Former Member]

Hi all.

I want disable (or set invisible, maybe it'll be better) this buttons of a custom infotype:

This infotype have an extension (ZPXXXX00, if it is for something). A loop at screen only process the objects of the extension. And I can't set another pf-status without this buttons (an error message says me it is forbidden and cancel the transaction).

Thanks in advance.

Any idea? It must can change (disable or enable) by code, because in some cases must be disabled, and in other must be enabled.
