Allowing or disallowing attachments by type

BMC SaaS Operations sets the list of attachment file types that BMC allows and disallows in the environment. As a tenant administrator, you can further configure which attachment file types you want to disallow in your tenant. Users will be prevented from uploading the attachments with the file extensions that are disallowed as per your company policy.

Important

The attachment file name should not include a comma (,).

BMC Helix Platform stores attachment file name as file-name-withExtension, MIME Type of file if supplied. If an end user uploads a file which has a comma in its name, the attachment is attached and saved in the record definition. However, BMC Helix Platform assumes that the MIME type of the document appears after the first occurrence of the comma, and truncates the strings after the comma.

When this attachment is downloaded, it might be missing the extension type and is downloaded as a file without an extension.
