SAP Connector form – Completing the Request tab

Use the Request tab to configure the data mapping for the outgoing SOAP message to the SAP system. Use the Request Headers section to specify the data needed (if necessary) for the SOAP envelope header. Use the Request Parameters section to specify the data for body of the SOAP message.

This tab is displayed for the SOAP connector type only.

The data types of the outgoing parameters can be any of the primitive data types specified in the W3C XML Schema standard. If you used the Connector and Metadata Wizard to generate the connector rules and the WSDL file you identified defines its own complex types, the Data Type for a parameter is XML Page, which indicates that the outgoing parameter is an XML object.

Request headers

Use this section to map values for SOAP headers. The data type of a SOAP header is an element (an instance of the W3C DOM object org.w3c.dom.Element ). The value of a SOAP header must be well-formed, namespace-qualified XML, typically generated by an XML Stream rule. If your application requires SOAP headers that conform to a WS-Security format rather than using HTTP Basic authentication, you can define that header content here.

If the Applies To class of the XML Stream rule is the same as the Applies To class of the connector rule, you can create a data mapping that specifies the XML Stream rule in this section.
If the Applies To class of the XML Stream rule is different from that of the connector rule, call the XML rule from the connector activity and then create a data mapping for the property that holds the stream in this section.

Field	Description
Name	Enter the external name of the SOAP request header.
Description	Enter a text description.
Map From	Do one of the following: If the Applies To class of the XML rule that provides the value for this header is the same as the Applies To class of the connector rule, select `XML Stream`. To manually enter the XML content to be included in the header, select `Constant`. If the Applies To class of the XML rule is different from that of the connector rule, select `Clipboard`.
Map From Key	Do one of the following: If you selected `XML Stream` in the Map From field, enter the Stream Name (the second key part) of the XML Stream rule. The system uses the first key part (the Applies To class) to find the XML rule. If you selected `Constant` in the Map From field, enter the well-formed XML to be included in the request Header. If you selected `Clipboard` in the Map From field, select the property that holds the XML text. You can use a linked property reference to identify the property containing the value.

Request parameters

Field	Description
Data Type	Select the XML schema data type of the external value you are mapping. Select any primitive data type in the W3C XML Schema standard. See How to complete mapping details for SOAP and dotNet connectors for details about data types. The `XML Page` data type indicates that the parameter is an XML object with a schema described by the data transform specified on the Advanced tab and that this connector rule was generated by the Connector and Metadata Wizard. You cannot use the `XML Page` data type for a connector rule that you created without using the Connector and Metadata Wizard. Select the `XML Literal` data type if the parameter is an XML object and you want to map the actual (literal) XML from an XML stream rule or a single-value text property. In this case, you must also specify Axis2 on the Advanced tab. For more information, see More about SOAP Connectors. If the SOAP operation style is `document-literal` and you are creating this rule manually, you can either specify simple argument-property mapping entries for the values in the message or use the XML Literal data type.
Name	Enter the external name of the request parameter.
Description	Enter a text description for this row.
Map From	Specify the source or the type of source of the value in Pega Platform. The choices that appear in the selection list depend on the data type specified in the Data Type field: `Clipboard` — The source is a property or page on the clipboard. `Constant` — The source is a fixed value that does not change. `XML Stream` — The source is a stream of XML data formatted by an XML Stream rule. `HTML Stream` — The source is a stream of HTML data formatted by an HTML rule. If more choices appear, they each identify a custom function rule in a `MapFrom` library. Review the function rule to determine what it does.
Map From Key	Specify the key to locating the property or rule in the source specified in the Map From field: Clipboard Enter a reference to a single value or page property. If the Connector and Metadata Wizard set the Data Type to `XML Page`, the Map From Key holds the page name of a page defined on the XML Page tab. Click the Open icon to review the property. You can use a linked property reference to identify the property containing the value. Constant Enter a literal text string. To include blank spaces in your text string, surround the string with double quotes. XML Stream Enter either the Stream Name — second key part — of the appropriate XML Stream rule or a page name and Stream Name using the syntax PageName.StreamName. The page must be on the clipboard for rule resolution to find the rule. If you specify the stream name only, the system uses the Applies To key part of this connector rule as the first key part of the XML rule. HTML Stream Enter either the Stream Name — second key part — of the appropriate HTML rule or a page name and stream name using the syntax PageName.StreamName. The page must be on the clipboard for rule resolution to find the rule. If you specify the stream name only, the system uses the Applies To key part of this connector rule as the first key part of the XML rule. a Rule-Utility-Function from a `MapFrom` library Either select the property that holds the value to be processed by the function or leave this field blank, as appropriate for the function.
