i want to update some values in order lines (quantity and user fields).
There are many problems:
1. odbdatasource.setvalue("quantity",0,200) is not possible
2. i can change the value by using omatrix.columns.item("11").cells(irow).specific.string=200,
but the availability check is coming up.
3. if i fill user defined values in my matrix, i have to display these fields (i hoped that this would not be necessary if i can set the value by datasource)
