Service File form - Completing the Request tab
Complete these fields to define processing and data mapping that occurs for each file or each record.
If the Processing Method on the Method tab is:
file at a time, complete only one row of the Parse Segments array.
by record type, complete a row for each record type, identifying each type in the Record Type field. The order of rows is not significant in this case.
record at a time, enter one or more rows in the order that the corresponding appear in the file. For example, if the file contains a single format, enter one row. If the file contains records in alternating formats, enter two rows.
|Initial Activity||Optional. Identify the name of an activity (in the class of the primary page) to run before processing each input file. If the activity you choose accepts input parameters, click the Params button and enter parameter values.|
|Parse Segments|| How the system uses information in this array depends on the processing method recorded in the Methods tab. |
When using a Parse Structured rule to extract property values from more than one record, use care to ensure that the cursor position is reset at the end of each input record. If a delimiter appears as the last character or characters in one record, it must be processed (or skipped over) so the cursor is in the starting position for the next record.
|Record Type|| Optional. Leave blank unless the Processing Method on the Method tab is set to |
Type the keyword
For example, assume the input files contain a mix of records with three different layouts — header, detail, and summary — indicated by a single character H, D, or S in byte 1 of each record. If your application needs to process all three types, create three rows in this array with H, D, and S in the Record Type . Records of each type must have a common length. On the Methods tab, enter 0 (zero) for the Record Type Offset position and 1 for the Record Type Length .
On the Methods tab, indicate the length and byte offset position of the record type within the record.
|Once?|| Select to apply this parse segment once. |
This option is useful for files that contain one header record followed by one or more detail records, such as in a Microsoft Excel CSV file. Select Once? in the first row to process the header rule. Leave this check box cleared in a second row, to process remaining records.
|Map To|| Enter the action to take in a parse step. Select one of these keywords or a function: |
Or enter the name of a function in the
|Map To Key|| Enter a corresponding key for the Map To field: |
Leave blank in most cases. When selected, the system uses two parameters from the parameter page for authentication.
The system uses values of two parameters
These two parameters can be set in service file processing by earlier rows in this tab can set these values.
|Activity||Optional. Identify an activity to run after the data processed by this row is parsed and arrives on the clipboard.|
|Keep Page?|| Select to cause the primary page of the activity identified in the previous field to be retained after processing of this row is complete. |
Clear to cause the primary page to be reinitialized to empty after processing of this row completes.
|Final Activity||Optional. Identify an activity (that applies to the primary page class) to run after the entire file is processed. For example, this activity may commit changes to the database.|
|Frequency|| Optional. Enter a positive number to cause the system to commit database changes after processing a number of input records matching that count. For example, enter 100 to cause a Commit method to execute after processing 100 input records. When this field is not blank, a final Commit operation also occurs after all input records are processed. |
If this field is blank, no automatic commit operations are performed.
This field supports the Global Resource Settings syntax (=.PageName.PropertyName). The default property name for this field is
|Success Criteria|| Optional. Identify a when condition rule to be evaluated after each input record is processed. If this rule evaluates to false, a database rollback occurs, backing out to the most recent commit operation. Processing of this input file is abandoned. |
The system records in instances of the Log-Service-File class the current processing status of each file, and can retry from that point. Checkpointing can work in conjunction with the Attempt Recovery fields on the File Listener form, to allow recovery from a temporary input/output failure.
