SERIAL NUMBERS

Hi Guys,

Can anyone tell me, what are "Serial Numbers" and their role in SD and other modules. How are they different from "Batch Numbers"?

Regards,

Vinod

    Serial Number Management :

     Serial Number Profile

     Working With Serial Numbers

     Serial Number Master Record

     Creating Master Records for Serial Numbers

     Serialization Data in the Piece of Equipment

     Maintenance of Configuration Data

    Serial Number Profile:

    Definition

    A group of data, summarized by a four-digit identification code, that defines the conditions and business procedures involved when assigning serial numbers to items of material.

    You enter the serial number profile in the master record at plant level for the material whose individual pieces are to be managed using material numbers. This means that an individual serial number profile can be assigned to a piece of material per plant. In this way a certain material can require serial numbers at one plant, and not at others.

    Structure

    The serial number profile contains the following information:

     The business procedures for which serialization

    – Can be performed

    – Must be performed

    – Is performed automatically

    – Is not performed

     Information on whether for a particular business procedure

    – Serial numbers can be assigned, for which a master record does not yet exist in the system

    – Serial numbers that already exist in the system as a master record must be specified

     Information on whether for a particular business procedure, a stock check should take place, and how the system should react in the event of inconsistencies

     The business procedures for which an equipment master record should or should not additionally be created for each serial number

     The equipment category that the system uses when assigning serial numbers automatically in the case of equipment master records.

    Working With Serial Numbers:

    Purpose

    You use serial numbers to identify items of material, which enables you to distinguish between the individual pieces.

    Process Flow

     You create a serial number profile in Customizing for Plant Maintenance and Customer Service.

     You create a material master record and enter a serial number profile.

     You create a batch master record for the material if it is to be managed in batches.

     You can create serial number master records in advance if you want to have a pool of serial numbers. From a technical perspective, an "incomplete" equipment master record is created for this.

     You can create configuration data for serial number master records.

     You assign serial numbers to the material when business procedures take place (for example, a goods receipt):

     Either you assign manually serial number master records that you created in advance, or

     The system assigns automatically new serial numbers and creates new serial number master records for this

    Serial Numbers in Sales and Distribution :

    Use

    It is possible to assign serial numbers in sales orders, inquiries and quotations, as well as for deliveries and returns deliveries. This makes it possible to track individual objects when goods movements take place (for example, sale of goods to a customer).

    Integration

    In order to use the serialization functionality in sales orders, inquiries, and quotations, you must have implemented the Sales component, and to use the serialization functionality for deliveries, you need the Distribution component.

    Prerequisites

    A serial number profile with the following procedures must be entered in the material master record:

    Profile Maintenance for Deliveries

     Procedure SDCC checks the serial number on goods issue. The serial number usage for it should be 03 = must.

     Procedure SDLS defines that the serial number should be created on delivery. The serial number usage for it should be 02 = can.

     Procedure SDAU defines that the serial number should be created in the SD order for items that are delivered. The serial number usage for it should be 02 = can.

     In this way, it is ensured that the serial number is assigned at the latest when the goods issue is delivered.

    SDAU This procedure makes possible the use of serial numbers in sales orders, inquiries and quotations

    SDLS This procedure makes possible the assignment of serial numbers for deliveries.

    SDCC This procedure makes possible the assignment of serial numbers when performing completeness checks for deliveries.

    SDRE This operation makes possible the assignment of serial numbers for returns deliveries.

    SDCR This procedure makes possible the assignment of serial numbers when performing completeness checks for returns deliveries.

    Serial Number Master Record:

    Definition

    Data record that contains information for serial number management. The serial number is given to an item of material in addition to the material number, in order to differentiate that individual item from all other pieces of this material. The combination of material and serial number is unique.

    Structure

    The following information is contained in the serial number master record:

     Status information

    You can establish here, which system and user statuses are valid for the master record. If necessary, you can set or delete the user status, display the authorized business procedures and set particular system statuses.

     Stock information

    You can see here in which plant and warehouse the item of material is located, or to which batch it belongs. You can also see what type of stock and special stock is involved. The stock information is recorded automatically when goods movements are performed, and cannot be changed manually.

     Partner Data

    Here, for example, you can use freely definable partner functions and partners to specify in Customizing which companies are responsible for the maintenance of the serialized material.

    Configuration data

    Here, you can configure a item of material according to its characteristics or make reference to a configured object.

    Example of Serial Numbers

    Company X manufactures solar collectors (panels). They produce three different types:

     Type A

     Type B

     Type C

    A material master record exists in Company X’s system for each type. For quality control reasons the company wants to know for each solar collector delivery which customer has received which type of solar collector, and which serial number(s) of the collector type was/were delivered to the customer.

    For this purpose, each solar collector that is produced is assigned a serial number that, together with the material number, uniquely defines it.

    In addition, company X wants to maintain and repair particular solar collectors that it sells directly to individual customers. For this reason, an equipment history is to be maintained for the collectors. Company X is able to do this by creating equipment master records for these serialized solar collectors.

    History

    Use

     You can use the history of the serial number master record to ascertain which procedures have affected the serial number. You can find all documents that have been created for the serial number here:

     Production and refurbishment order

     Maintenance and service notification

     Maintenance and service order

     Sales order

     Delivery

     Inspection lot

     Goods document

     Maintenance plan

     Maintenance contract

    Status Management

    Use

    Serial number processing is linked to status management. There are two different types of status:

     System status

    System statuses are set when you execute a particular function for the serial number. For example, you post a goods receipt in the warehouse and set the status In warehouse by doing this.

    User status

    User statuses enable you to further delimit functions allowed for a serial number on the basis of a system status. You can assign and delete user statuses yourself if you have the authorization to do this.

    Copying the Partner into the Serial Number :-

    Use

    Within the framework of a delivery, partner data is automatically transferred from the delivery note into the master record of the serial number when goods issues are posted.

    Prerequisites

     You have set the indicator Copy Partner in Customizing for Plant Maintenance and Customer Service under Plant Maintenance and Customer Service ® Master Data in Plant Maintenance and Customer Service ® Basic Settings ® Partner Data ® Copy Partner Functions to Master and Transaction Data.

     Furthermore, you have assigned the partner determination procedure and the corresponding functions to the equipment category under Technical Objects ® Equipment ® Assign Equipment to Partner Determination Procedure.

    Features

     The system copies the partner data from the delivery note into the serial number master record.

     If partner data has already been specified in the serial number master record, this data is overwritten with the data from the delivery note. However, the system only overwrites partner data for which the indicator has been set in Customizing.

    Creating Master Records for Serial Numbers:

    Use

    You are able to create directly master records for serial numbers during the assignment of serial numbers for various business procedures, if the serial number profile allows this.

    In addition, you can create master records for serial numbers in advance. This would make sense if you want to have a particular quantity of numbers in the system, that you can assign during a business procedure. in particular, this is the case when you are using serial number profiles that require serial numbers to already exist for certain business procedures.

    Activities

    You have two options for creating serial number master records for a material in advance:

     You create an individual serial number for a piece of material.

    You use this option, for example, if in make-to-order production you manufacture one item per day.

     You create several serial numbers simultaneously for a piece of material.

    You use this option, for example, if in repetitive manufacturing you manufacture several items per day.

    You can also create serial number master records if no serial number profile is entered in the material master record. However, use in business procedures is only possible if the serial number profile has been entered in the material master record.

    Working with Serial Numbers in Deliveries:

    Maintaining Master Data for Serial Numbers in Shipping

    Assigning Serial Numbers in Deliveries

    Deleting Serial Numbers from Deliveries

    Creating Equipment in Deliveries
