To ensure the Project dimension is shared and the data is integrated correctly across Financials, Workforce, and Project frameworks, the company should take the following actions: In the Workforce framework, rename one of the custom dimensions to 'Project' and enable it. This will allow workforce data pertaining to projects to be captured correctly. Additionally, ensure the granularity in the Workforce framework is set at the Employee or Employee and Job level. This granularity is necessary for tracking employee utilization accurately in relation to projects.

When setting up a data map, two options are available for handling unmapped dimensions. One is selecting multiple unmapped dimension members of the source to map to a single unmapped dimension member on the target. The other is selecting a single unmapped dimension member of the source to map to a single unmapped dimension member on the target. These are the correct methods to handle unmapped dimensions in data mapping, ensuring that the target dimension accurately represents the required information from the source dimension without creating unnecessary complexity by mapping multiple target members.
