When an administrator clicks 'Save' after making changes to Knowledge data categories in a category group and their positions in the hierarchy, three actions can occur. Users may temporarily experience performance issues when searching for articles due to the system processing the changes. The contents of the category drop-down menu change to reflect the new structure. The articles and questions visible to users also change based on the new category settings and their visibility rules.
To ensure article managers use specified values for custom article fields, making the field required on the page layout is the most effective approach. This method forces users to provide a value for the field before they can save the article, ensuring that the specified values are used consistently.
To meet the requirement of changing the Current Customer field on the Accounts object to 'Yes' when any related opportunity is successfully closed as won, the most appropriate solution is to use a workflow rule on the Opportunity object. This workflow rule can be configured to update the Current Customer field on the related Account. Apex triggers are unnecessary for this simple field update, and approval processes are not suitable for this scenario. Roll-up summary fields are also inappropriate because they are for aggregating data from related child records and can only summarize numeric data. Therefore, using a workflow rule on the Opportunity object is the correct approach.
