| Companies often order components from purchase business partners who do not produce the components themselves. These intermediate purchase business partners offer equivalent components, items that conform to their original item's specifications, from different manufacturers. In ERP LN, the following functionalities are available that enable you to define, approve, and use manufacturer's items: Multiple manufacturer item functionality. Manufacturer part number (MPN) item functionality. Important! If you did not use the multiple manufacturer item functionality in a previous version of Infor ERP LN, you cannot set up multiple manufacturer items in the current version. You must use the MPN functionality to purchase manufacturer's items. The reason for this is that the MPN item functionality is the preferred and most extensive functionality. If you already used the multiple manufacturer item functionality in a previous version of Infor ERP LN, for each item you can choose whether you want to define it as a multiple manufacturer item, or as an MPN item.
