batch pricing

hei all,

i have this requirement.

we're paid based on service to move COAL to stock pile. we're using Batch, so when Production planning doing GR, they will input value (distance). let say characteristic value in the batch = 1249 Meter. then we have rate = 1$/meter.

so when i sales order, we input material n batch number, the price will determine based on value in batch characteristic --> 1249 Meter * RATE (1$/M). the price will be 1249 $

how we do that?

best regard,

Hendry
