Hi Pieterjan,
Do you need to select the cell?
What about directly update the cell content ?
I haven't tried this, but I think it will automatically put the focus on that cell.
Dim editAddressShip As SAPbouiCOM.EditText = b1Matrix.Columns.Item("20").Cells.Item(4).Specific
editAddressShip.String = "ABC"
Regards
Edy
