Function documentationTransfer of Bill of Material (BOM)

 

This function enables the transfer of BOM master data from SAP ERP to create or update the corresponding BOM record of the Master type in SAP ME (see Bill of Material (BOM)).

This function supports long material numbers (see Transfer of Long Material Number).

Integration

  • The BOM contains essential master data for integrated materials management and production control.

  • The data stored in the bill of material serves as a basis for production planning activities in ERP such as the following:

    • In Material Requirements Planning (MRP) to calculate cost-effective order quantities for materials

    • In Production Planning and Control to plan the provision of materials

  • SAP ERP BOM Usage is not used in any business process in SAP ME. It is used only to determine a unique key for SAP ME BOM.

  • SAP ERP does not allow sending alternate BOMs using the transaction BD30.

  • SAP ME defaults the first BOM to version A and increments an additional integer value for subsequent updates. For example: A-01, A-02. A new BOM version is created when you change the following in SAP ERP:

    • Material numbers of ERP BOM item

    • Subitems quantity of the ERP BOM item

    • Quantity of ERP BOM item

    • ERP BOM status

    • Quantity of ERP BOM header

  • The last new BOM successfully created in SAP ME from receipt of the SAP ERP BOMMAT03 IDoc is always set to Releasable and marked as the current version of that BOM.

  • SAP ME does not use SAP ERP validity dates and lot size.

    Make sure that you always transfer the actual BOM.

  • Any BOM items without the material value are filtered out. SAP MII detects these types of components in the SAP ERP BOMMAT IDoc and does not send them to SAP ME.

  • SAP ERP BOM sub-items are transferred as reference designators into SAP ME (see Reference Designator).

  • SAP ERP BOM items with Alternate Item Group

    Alternates in SAP ME are identified by alternate item group that can be maintained in SAP ERP at the item level. The first item of the group is a component in SAP ME BOM; all the other items of the alternate item group are alternates in SAP ME BOM.

    Note Note

    All items in an SAP ERP alternate item group must have the same unit of measure and the same item quantity.

    End of the note.
  • Unit of measure of SAP ERP BOM item quantity must be the base unit of measure of this material.

  • The transfer of co-products, by-products, phantom components, and phantom members are not supported. They are transferred only with production order and planned order. For more information, see Transfer of Production Order with BOM and Routing and Transfer of Planned Order with BOM and Routing.

  • The deletion of distributed BOMs is not supported.

Quantities and Units of Measure in BOM

In SAP ERP you can define the header material of a BOM with a unit of measure different than the base unit of measure. SAP ME takes the quantity in the base unit of measure from the BOM header to normalize the BOM item quantities. The Assembly Qty of the BOM component in SAP ME BOM Maintenance is the base quantity of SAP ERP BOM item divided by the base quantity in SAP ERP BOM header. The Unit of Measure of the BOM components is taken from SAP ERP material master.

Activities

When you create or update a BOM master record in SAP ERP and send it to SAP ME, SAPMEINT creates or updates the corresponding BOM record of the Master type in SAP ME.
