If you’re using SAP EWM, you’ve probably noticed how serial numbers are managed in your system. But do you know what else you can do with them? With the configuration options available in SAP EWM, you can make the most of serial number management to save time and money. In this article, we’ll show you how to set up serial numbers in SAP EWM and some ways that you can use these numbers to streamline your business processes.
Serial Numbers on Material Master
In order to manage serial numbers in SAP EWM, you must first ensure that the serial numbers are entered correctly on the material master. This can be done by entering the serial numbers manually or by uploading them via LSMW. Once the serial numbers are entered on the material master, they can be managed in SAP EWM using a variety of methods.
Scenario 1 – Single Plant, Multiple Sites
In a single-plant scenario with multiple sites, you can use serial number management to keep track of stock at each site. This is especially useful if you have products that are only produced at certain sites. For example, you could configure site A to only produce product X, and site B to only produce product Y. This way, you can keep track of which site produced what product and when.
Serial number management can also be used to keep track of different batches of products. Imagine that your company produces three types of paper towels, each batch coming out every six months. You might set up your serial numbers so that the first digit represents which type of paper towel it is (1 = Regular 2 = Extra Absorbent 3 = Extra Soft), while the next two digits represent the month it was manufactured (01=January 02=February). With this setup, you can easily tell how many boxes you need for any given day.
Scenario 2 – Single Plant, Multiple Production Lines
In this scenario, you have a single plant with multiple production lines. Each production line has its own set of serial numbers. You want to be able to track and manage these serial numbers in SAP EWM. There are two ways to configure this in SAP EWM: Create one entry for each serial number or create one master entry for all serial numbers. Choose the method that works best for your business needs.
Single Plant, Multiple Production Lines – One Entry per Serial Number: Create an entry for each production line’s serial number. For example, create an entry called A-Line that stores A Line’s serial number and assigns it as A Line’s default record type.
Scenario 3 – Central Materials Management System (MM/PM System)
In this scenario, you want to configure your system so that serial numbers are managed centrally in your MM/PM system. This way, you can have a complete overview of all serial numbers in your system and can avoid any duplicate entries. To do this, you’ll need to follow these steps:
- Go to transaction SPRO and navigate to Extended Warehouse Management –> Cross-Docking –> Serial Numbers.
Scenario 4 – Expanded Production Across Geographic Regions
In this scenario, you have a large production area that is geographically separated into multiple regions. You want to be able to track and manage your serial numbers across all of these regions from a central location. You configure different SAP EWM sites to store its own serial number history on a regional basis so that they can be managed independently. The regional sites are configured as regional processing centres with each site representing one region.
