What ERP systems have you worked with? What SAP functionalities?

I have worked with several ERP systems, including SAP, 1C, and Oracle ERP. In SAP, I have experience with modules MM (Materials Management), SD (Sales and Distribution), and FI (Financial Accounting). The main functionalities I interacted with included configuring business processes, integrating with external systems, as well as analyzing and optimizing procurement and warehouse management processes. For example, I participated in a procurement automation project where I configured approval workflows and integration with supplier systems.
