At end user level, it is very difficult to understand the entire system ladscape in any organization. You should look for end user manuals in various functional areas which can provide useful information or look for softwares installed on your PC such as SAP GUI which shows that the organization is using SAP. You should also take inputs from your collegues in other departments to understand their processes which may involve different ERP systems. IT department of a organization can also provide valuable details about system landscape.
