If you create a dataset and then use the dataset in a table in the
report (Even if the table is hidden) you can get the row values and
store them in a variable. For example, on a table's detail row you
could add an oncreate script like:
myvar = this.getRowData().getColumnValue("QTY");
Look at the bindings tab in the property editor to get the column names.
Once you have the var you can also store it globally lie:
reportContext.setGlobalVariable("mygvar" , myvar); or like
reportContext.setPersistentGlobalVariable("mygvar" , myvar)
You can then use this variable downstream by calling
reportContext.getGlobalVariable("mygvar"); or
reportContext.getPersistentGlobalVariable("mygvar");
