In the admin console, under Data->Codes->Service Call->Service Call Resolution Category
I have unwanted categories that i would like to remove. Unfortunately i cannot do this because the categories have dependent relations, so i was wondering if there is some way that you can hide/block these unwanted categories so that users cant see and select them when closing a service call.
Indeed, you can't delete those categories due to their relations with previously service calls. But, you can block the unwanted, using associated check box field 'Blocked'. There is no doubt, after that, will be not visible to be selected when a new SC will be raised.
the other way to delete the unwanted category codes is, identy those you want to delete, using Advanced Find option search for all calls having the category value, move to another category (say a dummy category). Once you make sure that this task is done on all unwanted categories, then you may go ahead and delete the listed category. This will reduce the number of category values under the codes.
