Serial Number --- Doubts

Dear Experts ,

I have read many blogs & discussions regarding serial number but still I am having doubts regarding this concept,

My doubts are ;

1. Is Serial number profile created for one material code or individual materials ?

2. To process dismantling or assembling of equipments using ie4n , serial number is necessary , means equipment needs to be considered as material , so is it required to create equipment in mm01 t-code ??

3. After assigning serial number to each material & equipment , how to update that serial number created to respective material & equipment master data ??

    • Hope the discussion so far was not under misinterpretation of Material Quantity to be Material Serial number.

      The discussion so far is valid for the case below

      Suppose a pump has been procured with certain material code (which has got serial no profile activated by MM module). You have installed this pump and in PM module, you are treating it as an Equipment. So same object is Equipment for you and Material for MM. To integrate these two into one Masterdata the SerData tab is used.

      Your present question raises doubts about Equipment BOM and the BOM Quantities

      In this case the Pump has so many parts such a Bearings, Bush, Shaft, Sleeve etc. each installed in different quantities. If you are talking about these, you are talking about BOMs, possibly Equipment BOMs. See this picture

      This is made through Tcode IB01

      If you further ask about the Serialization of the materials shown in BOM, I'd answer that, usually serialization is not done here for use in PM module, because they are not mapped as Equipments.

    1. One material Code -- Many serial numbers.

    If 100 pcs of one material (with unique code) are there, it will have 100 serial numbers say 1 to 100.

    2. Equipments are create with IE01. Serial numbers are assigned in IQ01.

    3. Answered by 2.

    Also after activating Serialized data in IE02 (Edit --> View Selection --> Serial numbers) , when you try to assign a material you will be prompted last serial number of that material.

    • When in the Equipment master, the moment you have put the Material number and press Enter button, the Last serial number appears. You have to put the next serial number and save the Equipment master. i.e., Here I am giving value 4 by viewing at Last Serial number. Means you have already assigned this material to 3 more Equipments previously with SNo. 1,2 and 3.
