How to fill all column in SAP GUI SCRIPT by IF / IFEND

Question

As i was trying to RPA my SAP, I encountered a problem. by using SAP script recoding, i was able to fill these column one by one by this script code. under is my script code.

    `If Not IsObject(application) Then
   Set SapGuiAuto  = GetObject("SAPGUI")
   Set application = SapGuiAuto.GetScriptingEngine
End If
If Not IsObject(connection) Then
   Set connection = application.Children(0)
End If
If Not IsObject(session) Then
   Set session    = connection.Children(0)
End If
If IsObject(WScript) Then
   WScript.ConnectObject session,     "on"
   WScript.ConnectObject application, "on"
End If
session.findById("wnd[0]").maximize
session.findById("wnd[0]/usr/cntlCONTAINER_ALV/shellcont/shell").currentCellColumn = "FLIEF"
session.findById("wnd[0]/usr/cntlCONTAINER_ALV/shellcont/shell").pressF4
session.findById("wnd[1]/usr/lbl[1,3]").caretPosition = 6
session.findById("wnd[1]").sendVKey 2
session.findById("wnd[0]/usr/cntlCONTAINER_ALV/shellcont/shell")
session.findById("wnd[0]/usr/cntlCONTAINER_ALV/shellcont/shell").modifyCell 1,"FLIEF","1190361578"
session.findById("wnd[0]/usr/cntlCONTAINER_ALV/shellcont/shell").currentCellRow = 1
session.findById("wnd[0]/usr/cntlCONTAINER_ALV/shellcont/shell").triggerModified
session.findById("wnd[0]/usr/cntlCONTAINER_ALV/shellcont/shell").modifyCell 2,"FLIEF","1190361578"
session.findById("wnd[0]/usr/cntlCONTAINER_ALV/shellcont/shell").currentCellRow = 2
session.findById("wnd[0]/usr/cntlCONTAINER_ALV/shellcont/shell").triggerModified
session.findById("wnd[0]/usr/cntlCONTAINER_ALV/shellcont/shell").modifyCell 3,"FLIEF","1190361578"
session.findById("wnd[0]/usr/cntlCONTAINER_ALV/shellcont/shell").currentCellRow = 3
session.findById("wnd[0]/usr/cntlCONTAINER_ALV/shellcont/shell").triggerModified`

and so on.

However my rows are over atleast 100.

So what i want is it needs to repeat until it reaches the end of the row.

like this. The repeated data is same. Please teach me if there is a easier way.

Thank you.
