Account assignment distribution by quantity for Service item

Hi All,

We are using SRM 7, Extended Classic scenario.

we are creating shopping crat using multiple Cost center distributed by quanity for service item. when we distribute CC by decimal values then once the shopping cart is approved PO goes to Error in Process status and doesnt show any error and in RZ20 we can chek the error "Sum of percentages >100.1< exceeds 100 %" though the total quantity is correctly distributed. however when we distribute using whole number then PO is getting created and we can see it is ordered and replicated to bakend. Can anyone pleae tell me how to resolve this.

Thanks,

Veena
