Annotation (note) entity
The annotations (notes) provide easy ways to append additional information to any record in the
Dynamics 365 Customer Engagement (on-premises) database. An annotation (note) is a text entry that can be associated with any entity in
Customer Engagement. However, you can associate annotations with only those custom entities that are created with
the HasNotes property set to true in the CreateEntityRequest class. You can update a
custom entity, which is not enabled for notes, to have notes by setting the UpdateEntityRequest.HasNotes property to true.
Using the Web API, set the HasNotes property of the EntityMetadata EntityType controls this.
The Annotation entity represents an annotation (note), and contains the following information:
Annotation (note) text
Who created and modified the annotation (note)
Whether a file is attached to the annotation (note)
An attached file can be any standard computer file format that includes Office Word documents, Office Excel spreadsheets, CAD files, and PDF files. An attachment can be associated with any object, other than an annotation (note), in Customer Engagement.
To upload or remove an attachment, use the IOrganizationService.Update method or UpdateRequest message, setting the
Annotation.FilenameandAnnotation.MimeTypeproperties. This uploads an attachment that has been decoded into a base64 string format. The System.Convert.ToBase64String method can be used to convert the contents of a data file into a base64-formatted string. The maximum size of files that can be uploaded is determined by the Organization.MaxUploadFileSize property. This property is set in the Email tab of the System Settings in the Dynamics 365 application. This setting limits the size of files that can be attached to email messages, notes, and web resources. The default setting is 5 MB.
