If you are using the Quick Sizer on SAP website, then, after you create a project, it has a sidebar on the left-hand side of a screen. In the sidebar, there are nodes related to different modules of SAP S/4HANA like ‘Finance’, ‘Human Capital Mgmt.’, ‘Sales’, ‘Logistics Execution’, and so on. Please check the node called ‘Product Dev. & Execution’ for IM and MM components. You should be able to find them there.
