SFC Number 
A unique identifier representing a specific instance of a particular material being built during the manufacturing process
The shop floor control (SFC) number can have a quantity of one or greater than one. If the SFC number has a quantity of one, it can be the serial number of the specific instance of the material being built. If the SFC number has a quantity greater than one, it can be created to represent the lot of the specific instance of the material being built.
For example, PRINT900 is a material produced by the ABC plant.
The SFC number ABC5238 represents the specific instance of PRINT900 that is currently being built. For more information, see SFC Number Processing.
Structure
After its release and during its life on the shop floor, an SFC number can have one of the following statuses:
Status |
Description |
|---|---|
New |
Indicates that the SFC number has been created and released, but has not been started at any operation For example, an SFC number newly generated by Create and Release Demand at the first operation on the routing has a New status. |
In Queue |
In the POD, SFC numbers that are signed off have the In Queue status. For more information, see POD Pushbutton Activities. |
Active |
Indicates that the SFC number has been started at this operation In the POD, SFC numbers in the Active Work List have the Active status. Operators can complete SFC numbers with the Active status. |
Hold |
When an SFC number is on hold, it indicates that the SFC number should not continue through the manufacturing process until the hold is released (see SFC Place Hold). |
Done |
Indicates that the SFC number has done one of the following:
An SFC number with the Done status undergoes no more processing in the system. If the Track Inventory system rule under Production Tracking in System Rule Maintenance is set to true, the system automatically places SFC numbers with the Done status in floor stock, using their SFC numbers as their inventory IDs (see Inventory ID). End of the note. |
Golden Unit |
Indicates that SFC number has the Done status and is a perfect unit SFC numbers in the Golden Unit status are excluded from calculations such as yield (see Golden Unit). |
Done (Hold) |
Indicates that the SFC number has the Done status and is on hold |
Scrapped |
Indicates that the SFC number has been scrapped (see SFC Scrap/Delete) |
Invalid |
Indicates that the SFC number has a quantity of zero The system sets an SFC number's quantity to zero when the SFC number is serialized, split, or merged into another SFC number (see Serialize, SFC Split, and SFC Merge). |
Returned |
Indicates that the SFC number has been returned |
Deleted |
Indicates that the SFC number is marked for deletion during archiving, but the system has not yet deleted it (see Archiving and SFC Unscrap/Undelete) |
NoteEach SFC number can have only one status at a time.
Integration
The system generates SFC numbers on release of a shop order (see How SAP ME Generates SFC Numbers). You can also generate an SFC number using Create Trackable SFC (see Create Trackable SFC).
You can view and change system rules that control how data is handled during SFC number serialization and split and those that determine SFC number statuses in System Rule Maintenance (see Serialization Rules and Order Rules).
You define numbering patterns that uniquely identify SFC numbers in Next Numbering Maintenance (see Numbering Patterns).
