Enter a text description of this field.

Select a mapping type. Select Clipboard to map this value to a Single Value property on the clipboard.

See the description of the Map To field below for other choices.

Enter the target property name to which the data is mapped. Use the param keyword to place the data on the parameter page of the activity.

Field

Description

Enter the external data type of the request parameter: String, Integer, Bytes, All Chars, All Bytes, Double, or Boolean.

If you choose String, complete the Length field.

To read the entire message buffer as one variable-length text or binary data, specify All Chars B-24313 or All Bytes in the first row of this array, and leave the Length field blank. Leave other rows blank. In this case, the system does not read the length from the message buffer.

Optional. Enter an offset number to determine where the system positions the internal cursor before reading the data to the buffer. B-20115 wizard

Used only for text (String) and binary (Bytes) data types. Enter a fixed length for the data being read: B-20115 wizard

• If the data type is String, this is the character-length of the text value being read.
• If the data type is Bytes, this is the length of the byte-array being read.

The system truncates data values longer than the specified length. It pads data values shorter than the specified length with white space (for text values), or zeros (for binary values).

If you don't specify a data length for a text or binary value, the system expects and reads an integer representing the actual length from the data buffer immediately before the data value is read.

Enter a text description.

Select how the system creates the request parameter values:

• Clipboard — The system maps the data value from the scalar property specified by the Map From Key. This is the default value.
• Parse Structured — The system applies a Parse Structured rule. This option is available for Bytes and All Bytes in the Data Types field. B-15816
• Requestor ID — The system reconnects an existing requestor using the requestor ID value returned in the response message buffer of a previous service request.
• Username — The system authenticates the information using the provided user name value.
• Password — The system authenticates the information using the provided password value.
• Parse XMLRule — To indicate that the incoming data value is a stream of XML that can be parsed using the data mappings specified in a Parse XML rule.
• HTML PostData — To indicate that the incoming data value is a stream of data posted from an HTML form that contains property key/value pairs in POST format.

If more choices appear, they identify a custom function rule in a MapTo library. Review the function rule to determine what it does.

Provide a target to complete the value you selected for the Map To field:

• If the Map To value is Clipboard, enter the property name into which the data is to be mapped.
• For Requestor ID, Username, HTML PostData, or Password, leave this field blank.
• If the Map To value is XML Parse Rule, enter the Namespace name (second key part) and the Element Name name — third key part — of the appropriate Parse XML rule. Separate the Namespace from the Element Name with a space. That is, use the syntax "NamespaceName ElementName" and not "NamespaceName.ElementName." The system uses the page class of this service rule as the first key part of the parse rule.

• To maintain backward compatibility for service rules created in releases before V5.2, you can specify a data mapping with only a Namespace value. In that case, the system determines the Element Name key at runtime from the root element of the incoming XML document. However, this mapping works only if the Parser Type of the Parse XML rule is set to DOM and validation is not enabled. As a best practice, specify both the Namespace Name and the Element Name of the rule. B-21542

• If the Map To value is HTML PostData, leave this field blank. The name/value pairs in the string will be mapped to the parameter page of the service activity rather than the primary page.
• If the Map To value is a Rule-Utility-Function from a MapTo library, either select a property to hold the results of the function or leave this field blank, as appropriate for the function.
