| Material Fund Change Expenses [Text Block] | For the year ended November 30, 2024, total annual Fund operating expenses after waivers and/or expense reimbursement, after taxes for Class R6 shares increased from 3.20% in the year ended November 30, 2023 to 10.72% primarily due to an increase in current and deferred tax expenses. |
| Material Fund Change Risks Change [Text Block] | ■ Effective December 1, 2024, the Fund’s name was changed to PGIM Jennison Energy Infrastructure Fund, and the Fund’s principal investment strategies were modified so that, under normal circumstances, the Fund invests at least 80% of its investable assets in US and non-US securities issued by energy infrastructure companies, including master limited partnerships and “C” corporations. In connection with these changes, the Fund intends to invest in a manner that will allow it to be treated as a regulated investment company, rather than a “C” corporation, under the Internal Revenue Code of 1986, beginning with the tax year which runs from December 1, 2024 through November 30, 2025. As a result of these changes, the Fund’s principal risk disclosure was revised to include Tax Transition Risk , Infrastructure Companies Risk and Utility Sector Risk as principal risks of the Fund. |
