Data Mapping 

Purpose

This process describes how to map data from R/3 source fields to the target fields in a DME file. In most cases, you specify how data is to be mapped to elements, the nodes in the DMEE format tree that represent these target fields. You can also specify a mapping procedure and source information for atoms, which you define if an element contains several mapping rules.

Process Flow

  1. You insert an element in the format tree structure on the left.
  2. The system automatically displays the detailed view for an element in the right frame. This includes the following tabstrips: Attributes, Source, Conditions, and Aggregation.
  3. After you enter the required attribute information, select a mapping procedure.

Mapping procedures:

Select mapping procedure

If

Constant

The value is to be set to a constant

Structure field

A value is to be retrieved from a specific source field in the R/3 System

Reference to tree node

An attribute (current value, length, or counter reading) of another DMEE format object that was already defined is to be used

Aggregation

A value related to a reference node is to be totaled and made available to this node

Exit module

The standard mapping and conversion rules do not meet your requirements and you wish to specify an exit module

Own mapping (atoms)

Your mapping rules are dependent on conditions or if different parts of the element are to be filled from different sources

  1. Enter detailed source information:
    1. If you choose one of the following mapping procedures, enter source data in the appropriate fields on the Source tabstrip:

In most cases, you specify that the target field is to be filled from one source field from the R/3 System, which corresponds to the mapping procedure Structure field. To specify the source field, you can enter the source field and structure directly under Source, or you can select a field from the source field inventory.
    1. If you choose Aggregation as the mapping procedure, enter data as required on the Aggregation tabstrip.
    2. If you choose Own mapping (atoms) as the mapping procedure, you create as many atoms as you require in the form of subnodes to the element. You then specify a mapping procedure and source information for the atoms.
  1. You can specify a conversion method used to convert source field data to a particular format for the DME file. This step is optional; if no conversion method is specified, data is transferred to the target field in the format it has in the R/3 System.
