Loop - take value from two cells

[rohmadi02]

Hello..
I am new to VBA excel ..
I have a piece of VBA to be run on SAP application.
this code is running and should take value from cell in A & B but this is running only take value in cell A. it's does not touch cell B at all.
Also when there is NO further value / empty , the loop should be stop.

could you please advice what the syntax should be in this case?
Thank you .

Dim vNilai As Variant

With SAPSesi

.findById("wnd[0]").maximize
.findById("wnd[0]/tbar[0]/okcd").Text = "/NMM02"
.findById("wnd[0]").sendVKey 0

For Each vNilai In Workbooks("LoopTrial.xls").Worksheets("Sheet1").Range("A2:A20,B2:B20")

.findById("wnd[0]/usr/ctxtRMMG1-MATNR").Text = vNilai
.findById("wnd[0]/usr/ctxtRMMG1-MATNR").caretPosition = 8
.findById("wnd[0]").sendVKey 0
.findById("wnd[0]").sendVKey 0

'ActiveCell.Offset(0, 1).Select

.findById("wnd[0]/usr/tabsTABSPR1/tabpSP13/ssubTABFRA1:SAPLMGMM:2000/subSUB4:SAPLMGD1:2486/txtMARC-EISBE").Text = vNilai
.findById("wnd[0]/usr/tabsTABSPR1/tabpSP13/ssubTABFRA1:SAPLMGMM:2000/subSUB4:SAPLMGD1:2486/txtMARC-EISBE").SetFocus
.findById("wnd[0]/usr/tabsTABSPR1/tabpSP13/ssubTABFRA1:SAPLMGMM:2000/subSUB4:SAPLMGD1:2486/txtMARC-EISBE").caretPosition = 2
.findById("wnd[0]").sendVKey 0
.findById("wnd[0]/tbar[0]/btn[11]").press

Next vNilai

.findById("wnd[0]/tbar[0]/okcd").Text = "/n"
.findById("wnd[0]").sendVKey 0


End With
