Framework EDI Reference. Methods and Properties
ediDataSegment. Area

Returns the area or table number of the Transaction Set where the Data Segment is located.

Syntax:

• <lOrdinalPosition> = object.Area

Remarks:

EDI documents can be sectioned into header, detail and summary, which have an area (or table) value of 1, 2, and 3 respectively.  Not all documents have all three sections.  A segment can be uniquely identified by checking jointly its area, loopsection and ID.  Envelope segments (e.g. ISA, GS in X12, and UNB, UNG in EDIFACT) have an area value of 0.

Example

Dim oEdiDoc As Fredi.ediDocument
Dim oSegment As Fredi.ediDataSegment
...

Set oSegment = oEdiDoc.FirstDataSegment
While Not oSegment Is Nothing
    sSegmentID = oSegment.ID
    sLoopSection = oSegment.LoopSection
    nArea = oSegment.Area

    If nArea = 2 Then
        If sLoopSection = "LX;N1" Then
            If sSegmentID = "N1" Then
                txtCompanyName.Text = oSegment.DataElementValue(2)
                txtCompanyID.Text = oSegment.DataElementValue(4)
            End If
        End If
    ElseIf nArea = 3 Then
        If sLoopSection = "" Then
            If sSegmentID = "BIN" Then
                Set oDataElement = oSegment.DataElement(2)
                oDataElement.ExportValue sPath & "EXported" & txtPublicKey.Text
            ElseIf sSegmentID = "ERI" Then
                txtMethodSend.Text = oSegment.DataElementValue(2)
            End If
        End If
    End If
    Set oSegment = oSegment.Next
Wend
