This component determines how a batch is created and used in Production Planning PP through various stages of production and displays the result in a list.

You can use this to find out:

• In which other batches a batch was used
• From which other batches a batch was created

This is important in the case of complaints and questions about product safety if the composition of semi-finished and finished products has to be documented across all production levels. The material type is not important.

As well as batches, the system also displays production orders, manufacturing orders, subcontract orders, and vendor batches. This enables you to trace a batch’s progress through each stage of production.

The list is used for all plants, but can also be restricted to certain plants.

Batch where-used records form the basis of the batch where-used list. Batch where-used records are formed from the data from inventory postings and reversal postings in Materials Management (MM).

The function includes transfer postings between various batches, but not transfer postings from plant to plant or transfer postings from storage location to storage location.

The various batches in Production Planning are linked via:

• Production orders
• Process orders
• Subcontract orders

The function only displays batches for which a receipt posting or issue posting has been carried out. Batches that were chosen when an order was released are not displayed.

As well as Batch Management (LO-BM), you need the following components:

• Batch where-used file

The top-down analysis determines all batches that were used in the production of the specified batch.

The bottom-up analysis determines all batches in which the specified batch was used as a component.

After you have found out, using the top-down analysis, which component is defective, you can perform a bottom-up analysis to determine for which products this component was used during production and to which customers these products were delivered.

The list also displays vendor batches. For vendor batches, you can display the batches in which the vendor batch was used. You can also determine the usage or composition for these batches.

The list displays the totals of all partial quantities that have been posted for a batch.

For these totals, you can call up an overview of the posted partial quantities and the corresponding documents.

There are various ways of changing the scope of the display. For example, you can choose whether you want to display the current status of a batch or whether you want to cancel the analysis if all the postings for a batch have been reversed and there is therefore no quantity flow.

You can change the display options from the list and adopt them immediately by refreshing the list.

You can check the inspection lot assignment for each batch. From the list, you can then go to the inspection lot overview or inspection lot display.

You cannot use the batch where-used list function for purchase orders or production orders with account assignment because goods receipts are entered without specifying a batch number.

When several output batches are produced in a process order or a production order, the system forms a total for the input and output batches in the batch where-used list. With regard to the order number of the process order or production order, the batch where-used list cannot distinguish between various inputs/outputs (charges).
