Data mapping for SOAP and dotNet connectors
Data mapping defines the relationship between parameter-value pairs in external systems and property-value pairs in the Pega Platform. SOAP and dotNET connector forms have two tabs for data mapping.
- Request — Use this tab to specify how the connector rule maps arguments for the SOAP request messages from properties on the clipboard (Map From).
- Response — Use this tab to specify how the connector rule maps the reply message from the external service to properties on the clipboard (Map To).
For SOAP and dotNet connectors, the Pega Platform supports all primitive data types supported by the World Wide Web Consortium standard.
Simple data types
Because XML is text-based, any XSD data type can be mapped into a
Single
Value
property of type
Text
. However, when possible, a more
restrictive mapping is better — for example, the XSD type
float
corresponds
to the
Pega Platform
type of
Double
. In specific
situations, you may be aware of values and format that allow even more restrictive mappings
than listed below.
When an incoming or outgoing message contains scalar arguments that match the Pega Platform properties or activity parameters and the data is to be treated as a single value, create simple argument-property mappings. The following table lists the XSD data types that appear in the Data Type selection list and suggest the typical Pega Platform property type to map the value to or from.

Complex data types
To map complex data types, assess the data that will be transmitted in the SOAP messages. Consider whether the message contains a string parameter with XML code embedded in the value or the message contains an XML object:
-
If the message contains scalar arguments, the data in the argument is XML, and the SOAP
operation style is
RPC-encoded
. Identify the data type asString
and map the data from XML Stream rules and to Parse XML rules. Typically, the XML provides values from or for a complex Pega Platform property. -
If the message contains an XML object and you use the
Connector and Metadata wizard
to generate the rules, the data is mapped to and from the
data transforms specified on the XML Page tab and the data type is specified as
XML Page
. Typically, but not always, it means the SOAP operation style isdocument-literal
.
For information about using Parse XML rules, XML Stream rules, and data transforms (previously known as model rules) for data mapping, see Data Mapping XML, a document on the Integration area of Pega Community.
