Hi all,
I have a strange problem in attachment management.
for istance transaction ME52N and ME53N (change and diplay purchase requisition).
if you click the attachment service icon

you access to some GOS classes. I have found and enhanced the followin classes:
CL_GOS_ATTACHMENTS method SET_TOOLBAR
This allows me to deactivate some button from the tollbar menu.
The very surprising suff is even ME52N and ME53N belong to the same business object and GOS class should be the same the following toolbar is not handled by the mentioned method

So by using ME52N I can remove "CREATE" "DELETE" "CHANGE" icons, while in ME53N I cannot because the class/method is not the same
I have also tried to put some breakpoint to the following classes without success:
CL_GOS_TOOLBOX,CL_GOS_TOOLBOX_MODEL,CL_GOS_TOOLBOX_VIEW
Any idea?
Thanks in advance
Fabrizio
