Explain about batches and how are they searched?

The batches are the subdivisions of stock of material having the same characteristics and for example food production uses batches to indicate the day of production, paint production uses batches based on production date and the used ingredients and it's very hard to reproduce the same color in exactly the same way at two different moments. In the process to search batches using the standard search facility a match code F4, based on the naming convention of the batches or, for the batch classification, based on the characteristics of the batches.
