Thanks for your valuable input,
1. we have tried with blank the field in vb(3 as advice - (it works)
2. created condition record through vbo1
zrbt - 13.00 % , & zadd - 1.5 %
3. posted two billing through vf01 condition amount :
ZRBT 15600+9750 & ZADD 1800+1125
now when we come to vbo2 and click on
1. verification level button gives msg:
There is no sales volume for agreement 100
2. sales volume button the condition amount is not fetching from vf01
Please suggest.
