I, and others, can enter Time on those projects on his behalf.

Do you use OneWorld? Found this in SuiteAnswers: "If you use NetSuite OneWorld, the Intercompany Time and Expense feature and the related Intercompany Time accounting preference determine whether you can select a customer or project with a subsidiary different from yours. If the feature is not enabled, or if the preference is set to Disallow, you cannot enter intercompany time transactions. Instead, you can only select customers or projects with the same subsidiary to which you are assigned."

No, we don't.
