Costing Variant

Hi,

client used the price unit in acconting tab of Material master, but now they want to use the lot size in the costing tab for price unit what is the reason for that. In the config of the costing variant the "Pass on lot size = NO".

what is the difference b/t the prict unit & lot size is it something to do with the routing setup? In what condition we use price unit and what condition we use the lot size or does the system automatically picks it up?

Thank you,

Nivi
