Serialization is a way to keep track of individual items (material masters). When processing transactions, example Goods Receipt, Physical Inventory, etc.. you don't just type in material and quantity but also the serial numbers of the individual items. Serial numbers is a unique number that identify an item. Example if quantity is 2, one need to indicate serial numbers of the two items. A report is available to show all movements for a spesific serial number.
Lets go through a simple example to do a Physical Inventory posting on a material where we activate serial numbers.
Setting up -- Master data
A material is activated in Plant / Data Storage 2 view of material master. Field MARC-SERNP .The options (serialization profiles) are set up in configuration and define how it will be used (see below).
Using it in transactions
Lets look an an Inventory Management transaction for this material, transaction MI10 to do a stock adjustment and see where the serial numbers are used.
For this material, serialization is active, so the system force you to enter the serial numbers of the items, in this case the quantity was 2, therefore 2 serial numbers
Lets look at stock overview -- tcode mmbe and see if the serial numbers are visible.
Showing all the serial numbers
Double clicking on the serial number take you to transaction IQ03 -- serial number per material.
History of all inventory management transactions related to this serial number are visible by hitting the 'History' button
Setting up -- Configuration
IMG Menu: Sales and Distribution > Basic Functions > Serial Numbers > Determine Serial Number Profile -
For every profile, one needs to specify the area in SAP where it will be used and how it will be used.
Serial number usage:
01 - None
02 - Optional
03 - Obligatory
04 - Automatic
Equipment required indicates if a equipment is required.
01 - Proposal without equipment
02 - always with equipment
What did not work?
Something that didn't work as planned. I was able to issue (GI) the same serial number more than once. The system was unable to keep track that same number has been issued before. This is not good.
