Serial Number. Production Order Confirmation. GR. UD. Sales Delivery

Question

Hi Gurus,
Please help on this issue to get any user exits .....
As part of Serial number management, we have a certain issues on serial number confirmation, goods receipt from production order and quality inspection with UD.
Master data:
Finished product material master, Workscheduling view, Serial number profile maintained " ASRN"
Process flow:
1) Avalon Specific Serial numbers generation for finished goods through production order release status.
              (A11206000001)
                                    A  - Avalon
                                    1   - PCB Unit 1
                                    12 - Year 2012
                                    06 - Week
                                    000001 - Running serial number for the week.
2) Production order confirmation through CO11n transaction.
3) Production order Goods receipt through MIGO transaction against order.
4) Quality Inspection with Usage Decision through QA32 transaction.
5) Goods Issue for Delivery.
SAP Product Error:
1) System does not track and control the operation wise confirmed serial numbers during order confirmation.
2) System does not track and control the finally confirmed serial numbers during order goods receipt.
3) System does not track and control the last goods receipt qty in Usage Decision.
4)  For semi finished product, if we maintain serial number profile in workscheduling view, system is not showing goods issue material list in Co11n transaction for the finished goods.
5) Interfacing the serial number reading scanner with SAP,  is not working without entering material number and serial number manually.
6) System does not tracking and controlling the last Usage Decision done serial number during Goods issue to Sale order Delivery.

Hi Santha,
This is a bit vast, but I'll try to address at least some of the issues:
1- serial number in operation confirmation is not possible, for the reason that serailization is part of stock management, and as WIP in an order, this is not stock yet. Actually you cannot confirm the manufactured material either, and those 2 go together.
For tracking specificly WIP, there's something called WIP batches; you may look into it to see if you can use it.
2- during GR system will propose those SNs that you have defined for the order at release or creation.

4- GI in CO11N is provided only for BACKFLUSHED material components. Serialized materials CANNOT be backflushed.
5- You can use a barcode reader to read the serial number (instead of keyboard entry) when cursor is on the right field in the respective screen.
6- ?
