In the table under this tab you can register default part activities, with a code and a name. These activities will then become selectable under the Activities tab in the Update Part procedure in the Purchase, Sales, and Inventory modules.
You can also register part activities with new codes and names in the above mentioned procedures. However, these will then not be included in this table.
The activities that have been registered here can also be selected in the activity lists under the Activity templates tab.
