You can use the Logistics Data Warehouse to tailor the Logistics Information System (LIS) to meet your requirements.

The design of the information structures is instrumental for guaranteeing a high level of performance for updating and evaluations, as well as for ensuring that the statistical data is up-to-date and consistent.

To achieve these goals, Copy Management offers the following options:

  • reducing the system load by reducing the number of information structures to be updated
  • improving the evaluation performance by providing information structures with a high level of aggregation
  • enhancing statistical data with information that is not provided by the "normal" updating function
  • restructuring historical statistical data
  • simulating the effects of reorganizing data
  • preparing statistical data to satisfy special requirements (e.g. in accordance with planning requirements)
  • importing external statistical data to the LIS information structures
  • distributing statistical data over one or more information structures
  • providing a simple process for copying statistical data
  • enabling specific statistical data to be targetted for deletion

Every run of the Copy Management function consists of three steps:

  1. Reading statistical data

    The statistical data is either read from a source information structure in LIS or from any other data sources that you choose.

    In order to read the latter data, you can use the function exit RMCAF000.

  2. Adapting, enhancing and aggregating statistical data

    This step is divided up into two parts:

    1. The period unit of the information structures is converted, i.e. the periods of the source information structure are automatically adapted to the periods of the target information structure, where the period unit in the source information structure has to be smaller or equal to the period in the target information structure.
      2. If, for example, the source information structure is updated on a daily basis, but the target information structure is updated on a monthly basis, then automatic conversion takes place and it is aggregated into monthly values.
      In some cases, it is not possible to clearly convert periods, e.g. when the source information structure is updated on a weekly basis, but the target information structure is updated on a monthly basis. In this case, the data for the entire week is added to the month which contains the last day of this week.
      If the automatic period conversion does not suit your specific requirements, you can always create your own period conversion program manually.
    2. The system also offers the option of automatic aggregation, i.e. the contents of the fields (characteristics, key figures and units) with identical field names in the source and target information will be assigned to the target information structure from the source information structure.
      3. If the characteristics in the target information structure form part of the characteristics in the source information structure, i.e. if the target information structure has a higher level of aggregation than the source information structure, this automatic assignment will result in a logical aggregation from the source information structure to the target information structure.

      In addition, Copy Management also provides a function for automatic data enhancement. Automatic data enhancement enables you to adapt statistical data from master data and to enhance statistical data with additional master data.
      When using automatic data enhancement you can identify, for example, the current division for a material or the current MRP controller for a plant and material, and thus adapt the statistical data on the basis of these current allocations.
      If you want to make use of automatic data enhancement, proceed as follows:
      Start from the initial screen of Copy Management or from the work table, and select Goto -> Automatic data enhancement.
      If you have not yet fixed any methods for automatic data enhancement, select the function Edit -> New entries.
      Define both the source and target information structure. Source and target information structure can be identical.
      If you want to select an entry from the overview of the methods for automatic data enhancement that already exist, mark it and select Source field allocations. Here, you can specify, for the fields of the target information structure, those fields that are to be defined from the master data that is read.
      In the fields source table and source field, you define the place where the system reads the required allocation. If the current division, for example, is to be read from the material master, you must specify MARA as the source table and SPART as the source field.
      Caution
      For the system to read the source table, all of the key fields of the specified source table must be able to be supplied from fields of the source information structure. For this reason, the system tries to make the following allocations:
      If there are fields with the same name in the source information structure and in the source table, they will be allocated.
      In a further step, the system tries to make allocations by using the same data elements.
      Finally, the system tries to make allocations by using the same domains. F4 Help provides all the tables which satisfy this condition.

You can perform complex transformations of statistical data by using methods. You can branch to methods maintenance of Copy Management as follows:

  • from the initial screen of Copy Management via the function Goto -> Methods maintenance
  • from the work table of Copy Management also via Goto -> Methods maintenance

The procedure for this is described in Methods maintenance.

  1. Writing altered data to an LIS information structure

    The generated data records are automatically written to the target information structure.

    Key figures that can be cumulated (floating decimals, whole figures, packed numbers), which are indicated as such in the information structure definition, are added and then aggregated to values that already exist. The summation indicator is set for cumulative key figures in the information structure display.

    All other key figures are updated by data transport, which overwrites values that already exist.

    In addition to these standard procedures, the behavior of the key figures in Copy Management can be manipulated such that they can be aggregated, replaced, initialized (deleted) or excluded (not changed). These settings for key figure processing are effective persistently and across clients.

    If the source and target information structure as well as the source and target versions are identical, the source data is deleted and replaced by the target data. In this case, the system assumes that the statistical data will be updated with the help of Copy Management (for example, adapting the data after the sales areas have been reorganized).

    You can set the parameters of each Copy Management run so that data in the source information structure can be changed. You can use this option to indicate those data records that have already been processed, for instance.

    It is also possible to set the parameters of a Copy Management run so that the system deletes those data records of the source information structure that have already been processed.

    Caution

    If you wish to change source data, then online updating must be switched off for the assigned source information structure, at least in the area that is processed by Copy Management. This can not be achieved via the setting Lock Structure/Version described below.

Technical information

Source data is changed as follows:

If you have changed a data record, this data record will be deleted from the source table and then added to the source information structure in its altered form via MODIFY.

Caution

If you use a method to change key fields of the source information structure, then a data record that already exists under this key will be overwritten by the changed data record.

Activities

  1. Specify the name of the source information structure.
  2. Press Enter to reach the work table.
  3. Specify the name of the variant for the Copy Management run.

    You can use the pushbutton Maintain to branch to function selection.

  4. In the function selection of LIS Copy Management you define the settings for the further processing of the Copy Management run. In doing so, you select:

  • Data source
    • Info structure
      The source data originates from an information structure from the Logistics Information System.
    • @48@External Data
      External data is all data that is not saved in the LIS information structures. This includes all data in the tables of the R/3 System, as well as data read from a file. The&
