@wllmdjngh Basically if you want to use the SAP Login Plugin you need the official support SAP version 740 Final Release | Version 7400.1.0.1093 and its sub-version 740 Final Release | Version 7400.3.8.1123.
If that is not possible, you might use AutoIT to login and then VBScript to interact with elements in SAP.
Inside SAP you use the SAP Macro Recorder to generate the .vbs code that you will use in the Workflow.
Also please check to create the System Variables to it as the image below, after this it should work.
