You use split valuation for batches if – within value-based inventory management – you want to separate costs for externally processed batches from costs for internally processed batches, and you want to store the prices and values for groups of batches.
Split valuation for batches works on the same principle as the differentiation of partial stocks according to their origin, for example. In the split valuation procedure, you choose one valuation type for a batch.
Changing the Valuation Type
If you change the valuation type in the batch master record, the system does not change the valuation type in the movement data (for example, purchase order, delivery, order, and so forth). Also refer to Changing the Batch Master ).
When changing the valuation type, you must check whether the batch is contained in the movement data of business processes that are still open. Otherwise, the business process affected cannot be closed.
Upon goods receipt and goods issue of a batch, the system checks whether the valuation type from the respective document is identical to that of the stock to which the batch is to be posted.
If the valuation types are different:
The goods receipt is rejected
For the purchase order
For the shipping notification
For the production order
The goods issue is rejected
For the delivery
For the sales order
The reversal movement types cannot be carried out either.
There are two ways of closing these business processes:
You cancel the change you made to the valuation type, close the business process, and change the valuation type again.
You post the materials to a batch that has the same valuation type as the document, and then change the valuation type.
During invoice verification (purchase-order-based and goods-receipt-based) and order settlement (for a production order) the system copies the original valuation type.
Caution
You cannot change the valuation type if the batch is valuated on the basis of batch-specific units of measure and a price already exists for a characteristic that is relevant to valuation.
