Purchasing Info Record missing & Self-Service Requisition app not found in S/4HANA Cloud practice te

Hi all, I’m learning SAP MM (Purchase-to-Pay cycle) hands-on using an SAP S/4HANA Cloud, Public Edition practice/learning tenant. I’ve run into two issues and would appreciate guidance on whether these are expected limitations of a learning tenant or something I’m missing. Issue 1 — Purchasing Info Record missing at Source of Supply step When creating a Purchase Requisition and trying to assign a Fixed Supplier at the “Source of Supply” step, the system throws an error because no Purchasing Info Record exists for that Supplier + Material + Plant combination.
