Batch specific unit of measurement.

Dear Gurus,

My client is getting raw materials in ingots by unit of measurement in Weight.

But at the time of issue we have to consider lenght and weight. we can not use unit of conversion for the same because iron ingot diameter varies slightly, so we have decided to use the batch specific unit of measurement.

But after creating class and characteristic system is not showing the same in proportion unit in master data.

I think there may be somthing missing in the customization.

Kindly elaborate customization so that i can check and correct accordingly.

Thank you,

Anup.
