Our example of Resin production illustrates how batch specifications are determined.

You define these specifications as characteristics of a class and assign them to a class. You then assign this class to a material master record. When you maintain the material master record, you can thus specify the target values of the specifications.

In the classification system, you first set up a class for this material called Resin. Under the characteristics, you set up:

The values for a material can be interval values, although interval values are not allowed for a material. When the batch is produced, the specifications are checked in the laboratory and concrete values for each batch are determined. If these values lie within the specified range, the batch is acceptable.

Batch specifications can be assigned when goods movements are posted. The specifications of material 8172_3 can be proposed by the system. Material 8712_3 and the manufactured batches for material 8712_3 belong to the same class. A relationship between the two objects is thus established.

The validity of the specifications you enter is immediately checked. This is possible in the system as the material and the batches belong to the same class.

In our example, the actual values attained for the specifications for batch B03031995 are as follows:

In this example, a color value between 3.1 and 6.0 was expected for our material 8712_3. A color value of 3.5 was measured for our batch B03031995.
