2. Attach this field to the Detail line format of the PRTFIL function, and hide it.
3. In the action diagram for the PRTFIL function, specify that the output parameter Total Order Value from the PRTOBJ function be moved into this USR field.
4. Define a SUM function field Accumulated Order Value based on the Order Value field.
5. Add this SUM field to the Area, Country, and Final Total formats, supplying appropriate parameters.
