Edit a Data Mapping

Once a data mapping is configured, you can use the data mapper to open and edit it. Since data mappings are associated with group steps, the ability to reopen the mapper is also connected to group steps.

  1. To open a data mapping, right-click a group step and select Open XML Data Mapper.

    This will only work if the group step is the current step, that is, green. If it is not green, there may not be XML information to support the mapper.

    Alternatively, you can open the mapper for a group step that is current on the associated step view and click Open XML Data Mapper

  2. Once open, the mapper will behave exactly as described in Create a Data Mapping.
  3. Edit the data mapping steps manually if needed.

    Note that only certain changes are compatible with the XML data mapper. Opening a data mapping is subject to a number of conditions, essentially expressing that the group step MUST be a real data mapping.

    • The group step may not contain control structure in the form of branches, loops, or similar.
    • The group step must contain at least one extract or extract tag attribute step.
    • The extractions must all refer back to the same named tag.
    • The extractions must all have target attributes of the same variable.
    • For any given attribute of this variable, there may only be one extraction.
    • No extraction may use a tag finder where an asterisk '*' occurs.
    • All targeted attributes must exist in the underlying type.
