You can modify filters you created or default filters that come with ARIS. You cannot modify the content of the Entire method filter, which automatically contains all method items available on the related tenant.
To make only method items available to users that are relevant for their work, you must first manage the global sets of model types, object types and connection types that are contained in a filter. Then you must define how users can use these items:
Which objects can users place in each model type and which object symbols are available?
Which models can users assign to model objects and to connections?
Which attributes can users specify for models, objects and connections?
