Hi German,
In CRM4.0 you need add-On for service industries (CRMIS) for this. If you already have this, you can open category modeler by:
- Enter SE80 tcode
- Open CRM_BSP_FRAME BSP application
- Right click on select.htm page and execute it
- In the list just search for 'Category Modeler' or 'Rule Modeler'. Select and open it and you'll be able to setup it.
Kind regards,
Garcia
