Batch Determination for Process and Production Orders
You can use batch determination in process and production orders to
Find batches of components that are to be handled in batches, required for the production of a material
Conduct an availability check
Reserve the batches found at the earliest possible point in time for an order
If you do not want to reserve at batch level in the production/process order, but consider reservation at material level adequate, you can also run batch determination when you process a consumption posting for an order (see section Triggering Batch Determination for Goods Issues ).
You can use the following methods to allocate the selection criteria:
The component in the production/process order is classified manually
The component is classified in the bill of material for make-to-order production
A batch selection is manually specified in the sales order or a customer/material strategy exists
The component is classified in the bill of material (see section Classifying Material List Items and BOM Items )
A strategy is available for the material number of the component
Using the characteristics of the variant configuration in the sales order
The above list is identical to the sequence the system follows when it attempts to find a selection class.
Example
You use a certain raw material to manufacture 9 materials. You require batches with identical specifications for the production of eight of these materials, to produce the ninth material you require more detailed specifications. In this case, you create a search strategy for the raw material. For the ninth material, you classify the corresponding BOM item. As the system chooses selection classes using the sequence described above, the batches required for the eight materials are found using the search strategy, for the ninth material, the raw material is found using the selection class with which you classified the BOM item.
Even if the system does not use a search strategy to determine the selection criteria but one of the above methods, it nevertheless uses the batch determination rules (number of batch splits, sort rule etc.) specified in the search strategy. This means, you always have to maintain a search strategy.
