一些基础的操作SAP的Code

Open SAP

# Open SAP

Enter AP1 and logon

# Enter AP1 then Logon
def enter_sap_system(username, password, sid):
    try:
        # 登录AP1 (sid)
        log.info("Enter SAP system")

        app.window(title='SAP Logon Pad 770').wait('exists ready', timeout=60)
        sap_window = app.window(title='SAP Logon Pad 770')
        sap_window.child_window(class_name="Edit").set_focus()
        sap_window.child_window(class_name="Edit").set_text(sid)
