Material Maintenance

You use this activity to create material records (see Material). The system represents each instance of a material on the shop floor with an SFC number.

This activity allows you to do the following:

Assign a routing to the material for one or more types of shop order.
Assign assembly data types to materials on the Build tab page (see Build Tab)
Specify locations of the panel's pieces
Specify the custom activity the system runs at the PARSE_COMPONENT hook point for Assembly Point
Specify alternate materials on the Alternates tab page (see Alternates Tab)
Assign documents to materials on the Documents tab page
Define defects per million opportunities (DPMO) for materials on the DPMO tab page (see DPMO Tab)
Specify transfer settings for materials on the Transfer tab page (see Transfer Tab)
Assign material groups to materials on the Material Group tab page
Associate certifications with materials on the Certifications tab page
You can also assign the certification to one or more user groups (see Certification).
Override system rules at the material level on the System Rules tab page (see System Rule Maintenance)
Define settings for time-sensitive materials on the TSM tab page (see Time-Sensitive Materials and TSM Tab)
View variant characteristics and characteristic values of the Configurable materials sent from SAP ERP on the Configurable tab page
View selection rules associated with the profiles sent from SAP ERP on the Selection Rules screen of the Configurable tab
Enter custom data values (see Custom Data)
Browse a material according to search criteria

Prerequisites

Fields

The following tables describe fields requiring explanation:

Main Tab
Field	Description
Status	Releasable (default): Users can release shop orders for this material. Frozen: Users can release shop orders for this material, but they should not change this material record. Obsolete: Users cannot release shop orders for this material. This material record is no longer used. Hold: Users cannot release shop orders for this material. This status is temporary. When the hold issue is resolved, users can change the status of this record. Displays the last hold ID assigned to the material in SFC Number Place Hold activity. Note that if the SFC Number Place Hold activity was used to place a hold on the SFC number, this field is read-only and the hold ID appears next to this field. Use the SFC Release Hold activity to release it. New: Users cannot release shop orders for this material, but they can change this material record. This material record is new and not ready for production. Note that Frozen, Obsolete, Hold, and New material statuses do not prevent operators or machines from working on SFC numbers already released for this material. Hold Consec NC: Operators or machines cannot work on SFC numbers with consecutive nonconformances logged against them at the material. Hold SPC Viol: Operators or machines cannot work on SFC numbers with SPC violations at the material. Hold SPC Warn: Operators or machines cannot work on SFC numbers with SPC warnings at the material. Hold Yield Rate: Operators or machines cannot work on SFC numbers with yield rates below defined values at the material.
Type	Manufactured (default): The assembly is built in-house. You can release SFC numbers to the shop floor for the material, and maintain genealogy information for SFC numbers of this material if other settings permit it. Manufactured/Purchased: The component can be either purchased from an outside vendor or built in-house. Therefore, you can release SFC numbers for the material. Purchased: The component is purchased from a vendor. You cannot release SFC numbers for this material to the shop floor. Installation: The material is a work package used to build a collector material. Configurable: The material has several variants. These variants have characteristics (for example, color) that can have different values (in this example, red, green, blue, and so on). Their BOMs contain components that are only selected for a particular variant. Note that you import materials of the Configurable type from SAP ERP. Packaging: The material used to put onto or into products that are together. Note The material of the Packaging type can belong only to one container of the Packaging Material Type category. End of the note.
Order Type	Engineering: A shop order type used for engineering or as a prototype Inspection: A shop order type used to inspect incoming purchased materials Rework: A shop order type used for reworking an material after a first-time build Production (default): A shop order type used to build product to a specified quantity Repetitive: A shop order type used to build product continually on the shop floor. The quantity demanded can exceed the build quantity specified in a repetitive shop order. You can release SFC numbers for repetitive orders until the planned end date. RMA: A shop order type used to authorize the return of product to the shop floor for corrective action Tooling: A shop order type used for building tools that are used for manufacturing Spare: A shop order type used for producing spare materials Installation: A shop order type used to identify a work package that is used to build a collector material
Unit of Measure	The units of measure for the material such as pounds and meters
Routing	The routing used to manufacture this material You can assign a routing to the material for each type of shop order. See also: Material Assignment to Routing Note For Purchased components, leave this field blank . End of the note.
Routing Version	The version of this routing Note If you want to use the current version of the routing, leave this field blank. End of the note.
Routing Sent to ERP	If selected, indicates that the planned routing associated to the material is sent from SAP ME to SAP ERP. Note This field is visible only when the system rule Enable Replication of ME Routing to ERP is set to Yes or Yes, with Change Management (see ERP Integration Rules). It is a read-only field. End of the note.
BOM	The bill of material used to build this material
Lot Size	The planned lot size of the manufactured or purchased material. This field is used during the material receipt or creation of an SFC number.
Qty Restriction	Only 1.0: Limits the value in the Lot Size field to 1.0. Typically used for materials you build individually. Any Number: Allows the value in the Lot Size field to be any number, including decimal fractions, such as 5.25 Whole Number: Allows the value in the Lot Size field to be any whole number, such as 1, 2, 3
Qty Multiplier	The number the system multiplies the SFC number's quantity by when the SFC number passes through an operation set up to automatically run the SFC Quantity Multiplication hook point activity. The value must be a whole number equal to or greater than 1.0.
GTIN	The Global Trade Item Number. Note that you import the GTIN field values from SAP ERP.
Drawing Name	If you use SAP ME Visual Test and Repair (VTR), specifies the file name of the graphical model server allowing operators to view a CAD drawing of this material in SAP Visual Enterprise Viewer. This value is used in conjunction with the VTR Model Location system rule value to create a URL for the model file. For more information, see Visual Test and Repair Rules and Setting Up Visual Test and Repair.
Current Version	If selected, the version of this material is the current version.
Panel	If selected, this material is made on a panel (see Panel).
Require Serial Number Change Before Shop Order Is Done	If selected, you must change an SFC number of the collector shop order, using serialization before the shop order can have a status of Done. Note You must select this checkbox only if the material type is Manufactured and the Collector checkbox is selected. End of the note.
Collect Parent Serial Number	If selected, indicates the material must collect the parent SFC number of the parent material before the shop order can have a status of Done. Note You must select this checkbox only if the material type is Installation. End of the note.
Collector	If selected, the material is a collector for installation orders that are released and perform the tasks to build this material. Note The system uses the _SYSTEM routing. In this case, this routing has only one operation step. End of the note.
TSM (Time-Sensitive Material)	If selected, this material is time-sensitive and the fields on the TSM tab page are active (see Time-Sensitive Materials and TSM Tab). Note This checkbox is enabled only if the type of the material is Purchased or Manufactured/Purchased. End of the note.
Packaging Material Type	Packaging materials with similar requirements used for placing a product into or onto a packaging material. Note This field appears only if you select Packaging in the Type field on the Main tab in Material Maintenance. End of the note.
