An attachment category is assigned to an attachment as it is added to a work object, usually through anyone of several attachment-related local flow actions. The category name typically indicates the content or significance of the attachment such as:

• Expense reports
• Human resource documents
• Links to third-party Web sites

Using attachment category rules, developers can restrict a user's ability to perform operations such as add, delete, view, and edit attachments based on privileges, when conditions, and attachment types.

Attachment categories and types differ as follows:

• categories (Rule-Obj-AttachmentCategory rule type) are business classifications.
• types (Data-WorkAttach- class) indicate the format including note, file, URL, screenshot, or scanned document.

Implementing attachment categories

To support attachment categories in your application:

1. Create attachment category rules as necessary to control which users can create, update, delete, or view attachments to specific attachment types.
2. Update selected assignments in the flow rules of your application to offer users one or more of the standard local flow actions that support attachments.

Attachment categories in releases before V5.5

The Attachment Category wizard, appearing the Cases and Content slice () in V5.1-V5.4, is not available in V5.5. Create categories using category attachment rules. See More about Attachment Category rules for upgrade instructions.

Beginning with V5.5, you cannot associate attachment categories with custom types (a new subclass of the Data-WorkAttach- class). Categories used with custom types created in versions prior to V5.5 continue to function as originally configured. These categories cannot be upgraded to category attachment rules.
