Step 5. Create an array of structs and join data sources

Step 5. Create an array of structs and join data sources

Add and configure the same-day items array of structs. Using a filter, a join, and a field expression, you output only the items that were ordered and shipped on the same date.
Perform the following steps:
  1. Add a new output field with the following properties:
    Property
    Value
    Child Of
    PurchaseOrder
    Name
    SameDayItems
    Type
    array
    Array Element Type
    struct
    Element Struct Name
    sameday_str
  2. Add all the incoming fields from PODetail to the SameDayItems array in the output group.
  3. Delete the following field that you do not need in the output group: PurchaseOrder.SameDayItems.OrderNumber.
  4. Add POHeader as a data source for PurchaseOrder.SameDayItems array.
  5. Add a join condition for the PurchaseOrder.SameDayItems array with the following properties:
    Property
    Value
    Left Group
    POHeader
    Join Type
    Inner
    Right Group
    PODetail
    Join Condition
    :fld.{POHeader.OrderDate}=:fld.{PODetail.ShipDate} AND :fld.{POHeader.OrderNumber}=:fld.{PODetail.OrderNumber}
    The following image shows the data sources and join condition for SameDayItems:
    The Data Configuration dialog shows the selected data sources: POHeader and PODetail. The join condition shows Left Group: POHeader, Join Type: Inner, Right Group: PODetail.
  6. Add a filter condition for the PurchaseOrder.SameDayItems array: 
    :fld.{PODetail.OrderNumber}=:fld.{PurchaseOrder.OrderNumber}
