Every quantity in Bill of materials and work order position is stored in production unit.
Conversion between production unit and inventory unit is defined in the Conversion.
Note: In BoM you can define a separate Input Unit.
In this case the system calculates the production unit from input unit and the inventory unit from production unit
(Field OITM.U_me_verbr)
Sales UoM
Used for offers, customer orders, delivery note, invoice and all other documents in area Sales.
(Field OITM.SalUnitMsr)
Purchasing UoM
Used for purchases, delivery, purchase invoices.
(Field OITM.BuyUnitMsr)
Inventory Counting UoM
Unit for stock counting. Currently not supported by Beas.
(Field OITM.CntUnitMsr)
Input UoM
In the Bill of materials window you can define an own UoM.
From this Unit the system calculates the production UoM and from this the inventory UoM.
The warehouse unit is always used for postings. If a posting is done through Beas, you have the option to enter the quantity in consumption units or in warehouse units.
SAP Business One allows a subsequent change of the unit ID and description. In the item the description is saved, not the ID. Because Beas connects the ID with additional information, for example with rounding function, the ID and description need to match in SAP Business One.
In SAP Business One it is also possible to change existing unit ID. For example, "kg" can be changed to "ton". All existing items originally stored in "kg" are then stored in "tons". Inventory would change from 10 kg to 10 tons.
This is why there are restrictions in Beas:
Description and ID of the unit must be the same. IDs may not be changed subsequently.
