Bill,
Thanks for your reply.
If I am understanding correctly, you mean to say that dun by invoicing only updates dunning levels in FPL9 and FPM3.
So is there any event I can customized to achieve this purpose.
More over, I couldn't find documentation of that field. I have check both 4.7 and ECC 6.0 Library for additional function in invoicing but in vain.
Could you please enlighten me by sharing that link.
Regards,
Paresh
