Hi Prabhat,
Please check my KBA 1821733.
In normal case (not characteristic-based), withdrawal quantity is saved not only in //dp_head and //dp_sched tables, but also as "original quantity" in liveCache.
You can have a look at this in //rrp3, using command "gt_io" when you're in 'Element' tab.
If you see correct original quantity there, which is the same as withdrawal quantity, you can configure your SNP key figure as described in KBA 1821733, to make the key figure display "original quantity".
I have tried it in my internal system and it works perfectly 
Best Regards,
Ada
