Which two right-click options allows a user to attach a supporting document to a Form in their Workflow? Select two.

The option "Data Attachment for Selected Cell" is correct because it specifically enables users to attach documents relevant to the data within a specific cell of a form in their Workflow. This feature allows annotations or documents to be linked directly to the data, providing context and supporting information that can enhance understanding or assist in decision-making processes.

"Data Attachment for Selected Data Unit" is also correct for similar reasons. This option allows users to attach supporting documents to a broader context of data within a selected data unit rather than just a specific cell. By utilizing this option, users can ensure that relevant resources or documentation associated with specific data units are easily accessible and can be referenced during their workflow, facilitating better collaboration and validation of the data being processed.

The other options, while they may pertain to functionalities within OneStream, do not provide the capability to attach documents directly in the same manner as the correct responses, thus making them less relevant for this particular function.
