Step 5. Add an Expression Transformation to the Mapping

Step 5. Add an Expression Transformation to the Mapping

  1. Add an Expression transformation to the mapping, between the source and target objects.
  2. Link all the ports from the source object to the identical ports in the Expression transformation. For example, if your topic table includes the column
    EMPNO
    , link the
    EMPNO
     port in the source object to the
    EMPNO
     port in the Expression transformation.
  3. Configure the following additional ports in the Expression transformation: 
    DXPublicationInstanceID
DXPublicationInstanceDate
DXPublicationInstancePartitionDate
    The data type of all ports is string, and the minimum precision is 200.
  4. Link all the ports from the Expression transformation to the identical ports in the target object. For example, link the
    EMPNO
     port in the Expression transformation to the
    EMPNO
     port in the target object, and link the
    DXPublicationInstanceID
     port in the Expression transformation to the
    dih__PublicationInstanceID
     port in the target object.
  5. Save the mapping.
