Bom Quantity

Determines the requirement in input UoM per assembly in input unit (See Input UoM , Units of measure )

IMPORTANT: When an UoM Group is defined for an item, the UoM Conversion is applied based on SAP definitions and NOT the conversions defined in Beas.

You can define Material position with Quantity = 0

Example: For Material positions which you need only in processes related to the business work flow or production processes of a company.

Valuation

In precalculation / post calculation you can define if Beas should valuate this Plan/Real cost. See Configuration Wizard Value negative quantity.

Sometimes the user needs to indicate that several products are a result of a work order. These products can be:

•Co-product: Usable product, automatically generated during the production of the main product.

•By-product: A product that occurs incidentally or undesirably during the manufacturing of the main product.

•Dismantling: Disassembling of assemblies and returning components to the inventory.

In these cases, the BoM quantity is entered as a negative entry.

Negative BoM quantity behavior

Procedure or module	Negative Bom quantity is treated as
Order recommendations	Planned receipts.
Backflushing	Posted automatically or manually.
Work order structure	Displayed in the same color as assemblies but with another icon. Displayed positive (as receipt).
Posting	Manually, backflushed or posted in via collective receipt. See Collective receipt.
Merging work orders	Individual receipts are inserted as negative BoM items and posted correctly to the WIA account.
Sales order	Negative items can be reserved for sales orders.
Pre-calculation	Valued according to Configuration wizard > Precalculation > Value negative quantity.
Post-calculation	Valuation based on post-calculation is not possible.

A Bill of materials position can be a sub-assembly with own Bill of materials list and Routing position.

How to manage this in the areas:

Procedure or module

Result

Pre-calculation

Bill of materials defined as receipt (negative costs)

Valued according to Configuration wizard > Precalculation > Value negative quantity.

Routing positions cannot produce negative costs. These are always zero.

Post-calculation

Planned cost:

Bill of Materials: negative costs

Routing position: zero

Real costs:

Bill of Materials: Sum of all transactions

Routing position: Sum of all time receipts. It can only be positive value.

Configuration example for disassembling:

For disassembling, there is no main product. Use a service item (not storage-related) and define the resulting products in the BoM. Expected quantities are entered as negative.

Service item

|_ Product 1
|_ Product 2

Configuration example for a by-product:

For by-products indicate a main product on top level. This way you can work with off-cut and reuse waste material.

Main item
|_ Material
|_ By-product

Area Master Data

Quantity input UoM	BEAS_STL.INPUT_QTY If the stored value is NULL, MENGE_VERBRAUCH will be used. In th entry window, INPUT_QTY is entered, using INPUT_FACTOR the column MENGE_VERBRAUCH is calculated.
Input UoM	BEAS_STL.INPUT_UNIT Input UoM
Factor	BEAS_STL.INPUT_FACTOR Conversion factor from input unit to production UoM
Quantity Production UoM	BEAS_STL.MENGE_VERBRAUCH Requirment in production UoM. Reference quantity for all following calculations
Production UoM	OITM.U_me_verbr Production UoM from item master

If an issue or receipt document is created for this position or the position has order-related sub-assemblies, it is not possible to change the quantity.
