Adding an IMS Multiple-Segment Data Map - Example

Adding an IMS Multiple-Segment Data Map - Example

This example demonstrates how to add an IMS multiple-segment data map that defines a complex table.
In this example, you add multiple segments, one at a time, to create a hierarchical relationship between the segments in the complex table.
To create an IMS multiple-segment data map:
  1. Open a data map that contains multiple segments.
  2. On the
    Data Map
     tab in the
    Resource Explorer
    , right-click a table and click
    Properties
    .
  3. In the
    Table Properties
     dialog box, enter the following information:
    • In the
      Record Dependencies
       list, select a segment to make it the parent.
    • In the
      Available Records
       list, right-click a segment to add it as a child and click
      Add Record as Child
      .
    • In the
      Record Dependencies
       list, select the parent segment.
    • In the
      How do you want to handle multiple instances of selected record
       list, select
      New Row
      .
    • In the
      Record Dependencies
       list, select each child segment and set the multiple instances option to
      New Row
      .
  4. Click
    OK
    .
    For each segment in the hierarchy, you can set different options for the
    How do you want to handle multiple instances of selected record
     option. For example, set ROOT to
    Ignore
    , SEG1 to
    New Row
    , and SEG2 to
    Array
    .
    If a parent segment is set to
    Array
    , set all child segments to
    Ignore
    .
    You can also define segments at the same level. For example, add the SEG1 and SEG2 to ROOT segments as siblings.
