    Thomas,

    At their most basic functions, MM01 is to Create a Material Master, whereas IE01 is to Create an Equipment Master. Each results in a separate master data object. There is overlap for certain cases with spares, especially Rotables and Repairables, that are serialized. In this case, each serial numbered item is also an Equipment Object. It can be referenced by the Equipment number, or by the Material / Serial Number combination.

    For consumable spares, to create stock, use MM01 to Create a Material Master. Most use Material Type ERSA or HIBE for spares. You can use the MRP tabs to establish the stock levels, then run MRP to start the purchasing process.

    The Storage Bin is on the Storage Location tab, unless you are using Warehouse Management.

    I'm trying to be general and basic, since more detail depends on the version and your system's design. More detail is necessary to have a fully functioning process.

    • Jürgen is correct. Every company that has stock for Maintenance has found a solution to this question. Options: a) creating materials for you is added to the group that creates them for other uses, b) MM01 is authorized for you, with restrictions on the Material Type, Company Code, Plant, etc. so that you can only create them for your purpose, c) The creation is added to someone else's role with the restrictions.

      Start with the reason for the rule, and work from there. Most companies need multiple people involved in providing information for Material Masters, including Purchasing, Finance, and Costing.

      Getting Material Masters is just the start. You will then need to bring in the existing stock, set up how you will consume the stock, and set up how you will replenish the stock.

      All of this is standard, out-of-the-box, but does require multiple people working to set it up.

      Best of Luck,

    • IE01 is for creating equipment masters
    • MM01 is for creating material masters

    .

    Why do you ask?
