    Short Description

    EDIReader reads data in EDIFACT format. All EDIFACT versions from D.93A to D.21A are supported.

    EDIReader is currently only available to selected OEM partners. To find out more, please contact .

    Ports

    Port typeNumberRequiredDescriptionMetadata
    Input0⨯For port reading. See Reading from Input Port.One field (byte, cbyte, string) for specifying an input of the component.
    Output0✓For correct data records

    Any[1]

    1-n[2]For correct data recordsAny [1] (each port can have different metadata).

    [1]  Metadata on each output port does not need to be the same. Each metadata can use Autofilling Functions.

    [2]  Other output ports are required if the mapping requires it.

    Metadata

    EDIReader does not propagate metadata.

    EDIReader has a metadata template on its output port available.

    Metadata on optional input port must contain string, byte or cbyte field.

    Metadata on each output port does not need to be the same.

    Each metadata can use Autofilling Functions.

    EDIReader Attributes

    AttributeReqDescriptionPossible values
    Basic
    File URLyes Attribute specifying what data source(s) will be read (EDIFACT file, input port, dictionary). See Supported File URL Formats for Readers.  
    EDIFACT version 

    Attribute specifying version of EDIFACT message.

    		 
    EDIFACT message 

    Attribute specifying type of EDIFACT message. Possible values depend on selected EDIFACT version.

    		 
    Mapping [1]

    Mapping of the input EDIFACT structure to output ports. For more information, see XMLExtract Mapping Definition.

    		 
    Mapping URL[1]

    Name of an external file, including its path which defines mapping of the input EDIFACT structure to output ports. For more information, see XMLExtract Mapping Definition.

    		 

    [1]  One of these must be specified if EDIFACT version and EDIFACT message are used. If both are specified, Mapping URL has higher priority.

    Details

    EDIReader reads data from EDIFACT files using SAX technology.

    EDIReader can read individual values or entire subtrees of the EDIFACT structure. Individual values can be converted to any field type. Subtrees can be converted to variant fields. When reading into variant fields, all data types in the field will be string type.

    Using EDIReader is very similar to XMLExtract. Attributes EDIFACT version and EDIFACT message define the expected structure (schema) of the input data. The schema is generated automatically.

    Specifying EDIFACT version and EDIFACT message is optional. You can leave both attributes empty, in which case EDIReader will read entire input data into a single variant field on first output port. Defining a mapping is not possible in this case.

    EDIReader Mapping Editor and Message Schema

    EDIReader Mapping Editor serves to define mapping from EDIFACT message structure to one or more output ports by drag and drop.

    To be able to use the editor you have to specify EDIFACT version and EDIFACT message. The schema is created internally and cannot be modified.

    Any other operations to set up mapping are described in above mentioned XMLExtract.

    In EDIReader, you can map input fields to the output in the same way as you map message fields. The input field mapping works in all three processing modes.

    Examples

    Mapping parts of EDIFACT message onto output metadata. It is possible to map a whole message or its part onto variant field or to map individual values to fields of other data types.
