Designing the Process
To copy all values of a multi-valued attribute to a specific index of multi-valued indexes:
1. In the target tree, create a node representing the specific index of the multi-valued attribute.
2. Select the node representing all values (the index value for this node is ALL) in the source tree.
3. Select the node representing the single-attribute node in the source tree.
4. Launch the function dialog box by double-clicking on the function.
5. In the function dialog box, select FOR-EACH as the value for Input Context, and select
Over-Write, Insert Before, or Insert After as the value of Output Context.
When using the Insert After or Insert Before options, the values are inserted after or before the
index. When using the Overwrite option, the existing values are overwritten.
XML and other data formats
Since Extensible Markup language (XML) is the standard used to exchange structured data between
applications, the activity templates shipped with Process Builder support XML natively. Process
designers can associate an XML schema with a service-specific message and use the data mapper to
create an XML payload that can be sent to other applications. However, if the target application
uses another data format (like Comma Separated Value (CSV)), then associate a translator with the
message. At runtime, the Process Integrator uses a translator, if specified in data mapper, to convert the
XML document into the desired format. A translator is a custom Business Object Framework (BOF)
module that you write, for example, to convert a Comma Separated Variable (CSV) file to an XML
document. This is a standard feature of the data mapper.
Setting custom object types for attachments
In some applications, executing processes must receive email with attachments. The default object
type for an attachment is dm_document. However, you can also treat it as a custom object type by
using the data mapper for the Email Inbound activity template. In the data mapper, set the ObjectType
attribute in the Attachments node of the process data to any type that is valid for your repository.
Looping
Many applications must perform a series of activities several times in succession. Process Builder
enables you to define loops by using a counter mechanism. The following process shows how to set up
looping within a process. In the first activity, a human performer specifies a set of departments. Then,
an automated loop cycles through each department, invoking a process for each department.
