can user share public layout but no access to change global default layout?

Hi Dear Experts:

we want to restrict users from saving only global layout default on the

Portal. that means end user can create reusable layout but can not

change the default global layout.

we tried to remove the authorization object S_ALV_LAYO which is used to

determine if a user can save user specific as opposed to global

layout.and after remove this, users can only save user-specific layout

which can not be re-usable by others.

and we also found another parameter called I_DEFAULT that has to do

with default layout as well. It looks like this parameter is read when

take CATS_DA as an example program is executed, and it controls whether

or not a default layout (either global or user specific) can be saved

or not. SAP has set the I_DEFAULT value to u201Cxu201D, does that mean SAP

has u201Chardcodedu201D the I_DEFAULT value in the CATS_DA program to be u201Cxu201D so

users can set global default regardless of it being user specific or

global?

could you please help how can we block u201Cglobalu201D u201Cdefaultu201D layout

only but enable user defined global layout available?

Thanks very much for the help. Xiaoli
