My cusotmer's products are mostly MTO products and they have a lot of the meter controlled item such as electric cables.

The those meter controlled items are set "m" : meter as primaly UOM.

My question is that how to purchase the meter controlled Item based on manufacturing requirement easily?

Example :

Item Number : EC0001

Description : Electric Cable / diameter 2.5cm

UOM : m (meter)

A BOM requires EC0001 (3m) multiple 4 pc. ( One sub-assembly SA01 uses EC0001 (3m) and the BOM has five SA01)
