Summary Coloumn Problem

Question

I developed PO report, i created one summary column out side the group. I have place one field in under Group frame which it shows PO Grand Total, now user want at same place they dont move poistion, they would like to see PO indiviual Total, that means each po total instead of PO Grand Total.
If you run report for PO Range: PO From : 101 and PO From :102
PO:101
Item Price
ABC 1.1
DEF 2.1
PO:102
Item Price
ADE 1.5
DEK 2.5
PO TOTAL: 7.2(Right now it will show like these)
Now they need
PO No:101
Item Price
ABC 1.1
DEF 2.1
PO Total : 3.2
PO:102
Item Price
ADE 1.5
DEK 2.5
PO Total : 4.0
I can solve that problem easy way, but problem i dont want move any repating frames or any group frame, bcoz that total layout print on pre print stationary. With out chaning any thing instead PO Grand Total, can i show PO Indiviual Total(please remember po total field is in group frame, not in reapting frame).
Your early suggestion will aprreciate.
Thanks

Answer 1

To do this without any additional repeating frame will require that you calculate the value in format triggers and store the result in a PL/SQL package variable.
You can then use an srw.set_field_num(0, <plsql package variable>) to insert the PL/SQL package variable value into the total field in your layout.
The main problems with this approach are the difficulty in calculating, re-setting the value and ensuring the value is correct.
- Since the format trigger may execute more than once for any specific instance of the object, you also need something like a count column to make sure you only add the value once.
- You need to re-set the package variable on each change in the PO repeating frame (or create an array so that you have all values for all PO's).
