A configuration specification is defined as a list of characteristic/value, and optionally characteristic quantity, combinations for a base item. Each configuration specification is uniquely identified by a configuration ID, a system-generated number is used by the system to reference the desired configuration. Configuration values for the base item must be specified when you wish to work with a configured base item in a quotation, sales order, manufacturing order, etc.
When a valid configuration specification is created, the value combinations are compared to the other existing configuration specifications defined for the part. If an identical combination is found, the existing configuration ID is used. This allows the system to reuse configuration specifications, allowing the same configuration specification to be referenced by several orders.
Example of a configuration specification:
Part No: SPORTS CAR Configuration ID: 205
| Characteristic | Value | Quantity |
| HORSEPOWER | 200 | |
| COLOR | RED | |
| SPARE KEY SET | YES | 2 |
