Further refinement of the selected categories is possible to select/unselect which "Substance IDs" (regulations/queries) should this user-defined category contain.
However you cannot add new rules to this category. But you can remove regulated substances you have license for.
Click on the button on the left navigation bar to start the User-defined category editor.
Clicking the Create new category button a short guide is displayed:
After selecting a country (Switzerland) only one category (7144 - CH ... Narcotics List D) is selected for editing:
The table of the displayed regulations can be filtered by free-text search of Substance ID / Substance name / Category and System updates , plus in the Show dropdown llist the Selected/Unselected.
Above the table the Selected regulations ( Selected 182 of 188 ) are shown on the left and the Displayed (filtered) regulations ( Displayed 6 of 188 ) are shown on the right side:
In this example Not modified regulations containing ethylamphetamine and methylamphetamine were filtered and unselected from this user-defined category.
When there are existing earlier created user-defined categories saved in the system, clicking on the User-defined category editor icon displays a list of these in a table.
Opens the editor where you can easily review - with the above described filters - the Added/Modified/Deleted/Not changed substances in your custom category which were affected by the latest Knowledge Base update.
You can delete an existing user-defined category by clicking the Delete button in the Actions column.
A confirmation popup will be displayed that you should accept for the deletion.
Notifications column shows the number of substances - system updates - in a user-defined category that were Added/Deleted/Modified during the latest Knowledge Base update.
You can review and accept each user-defined category one by one selecting Edit in the User-defined category list.
What happens on a Knowledge Base update?
So before the Knowledge Base update all user-defined categories with Notifications should be reviewed and modified if needed.
A warning popup is displayed on a Knowledge Base update to remind you that all unaccepted notifications will become automatically applied.
You should review and accept each user-defined category - that has system updates - one by one selecting Edit in the User-defined categories table.
In the following example the user-defined categories were created with Knowledge Base v17.10.04.3 and the Knowledge Base was updated recently to v18.07.11.0:
Reviewing ( Edit ) the SwissEF user-defined category and applying the System updates filters (Added/Modified/Deleted/Not changed) in the above example, 20 substances were deleted, 38 substances were added and 2 substances were modified between the October 04, 2017 and the July 11, 2018 Knowledge Base.
Because Single check or File check can only be run against countries or category groups, a user-defined category group should be created that contains your user-defined category.
After that you can run the check against that category group.
