Batch Determination for Deliveries
Use
You should choose batch determination in deliveries, if

If batches have already been specified in the sales order, they are copied to the delivery, and cannot be changed there.
Features
Depending on the settings you have chosen in Customizing, there are two ways in which you can run batch determination when taking deliveries:
You still have the option of triggering manual batch determination, if you have already used automatic batch determination previously, but want to use other batches than those the system selected using the sort rules. If you want to use automatic batch determination, you need to make the appropriate settings in Customizing; see section Activating Automatic Batch Determination in S&D in the Implementation Guide.
As batch splits are possible for deliveries (see also
Working with Batches in Deliveries in the SD - Sales and Distribution Processing documentation), you can run batch determination at this point, if a batch determination in the sales order only located an insufficient quantity, but you have noticed that several batches with the appropriate specifications are available, that when combined would provide the desired quantity.
