Forms: File Exporter

A File Exporter creates files with a format that matches that of the input stream.

Form: File Exporter Details

The following fields are configured on the Details tab:

Field	Description
Name	The name of the file exporter.
Enabled	Tick when the configuration is complete and the file exporter is ready for use.
File Name Expression	An expression that generates the name of the file being exported. See CenterView Expression for further details. A number of Internal Variables are available in this expression: _fromDate: the start date of the period of the stream being processed. _toDate: the end date of the period of the the stream being processed. _inputMultiplier: the value returned by the input multiplier, if one is being used.
Output Directory Expression	An optional expression used to generate the name of the directory into which generated files should be written. See CenterView Expression for further details. Note that because this is an expression field, if you supply a simple directory definition in plain text it must be surrounded by quotes. Also, directory separators must be / and not \, even if the file is being written to a directory on a Windows platform. E.g. "C:/data/address/export/". A number of Internal Variables are available in this expression: _fromDate: the start date of the period of the stream being processed. _toDate: the end date of the period of the the stream being processed. _inputMultiplier: the value returned by the input multiplier, if one is being used. If no expression is provided, or the expression evaluates to blank, the generated file will not be saved to disk and CenterView will check that the Send By Email tab details are completed.
FTP Site	The FTP Site on which the generated file is to be moved to. If no site is specified then the file is assumed to be generated and left on the local machine. If a site is specified then all directory paths specified on this form should be the full path to the file since the base directory specified in system configuration is ignored (since the base directory is specific to the local machine).
Ignore Base Directory	Normally the base directory, specified in the "System Directories" tab of the "System Configuration" screen, is prepended to the output directory specified on this form. However, if this flag is ticked then this does not happen and the output directory alone is used as the full path specification for the export file.
Export File As	Files can be exported in the following formats: Comma Separated Files Excel Spreadsheet HTML File If Excel Spreadsheet or HTML File are chosen, a field to specify the Excel template for the data to be exported into will become available. If Excel Spreadsheet or HTML File are chosen and no Excel Template is specified for the File Exporter or in the Drilldown View, CenterView will export a table of data to Excel or HTML respectively. Note that the default format for Excel exports is set in System Configuration.
Overwrite Existing File	File exporters can now be configured to overwrite existing files with the same name as the file to be generated. This can be useful where you want CenterView to replace a file at regular intervals, e.g. to update the content of an HTML page on an intranet.
Character Set	The character encoding to be used. Select a value from the drop down list. If Other if selected, a new box opens and a new character set can be entered. Full list of available character sets can be found here (Canonical Names from both columns can be used).
Include Header Row	If ticked, a header line will be written to generated files containing the names of each field written in the following rows.
Line Separator Style	The user can specify the line separator on each file exporter where a particular exporter needs to use a style other than the system default. Options available are: Windows Unix Other The system default line separator style can be configured on the first tab of the system configuration screen. If a default style is not specified then the default will revert to be the default of the operating system on which the CenterView server is running.
Line Separator Chars	This field is only available if Line Separator Style = Other. Allows a custom new line separator to be entered. A sequence of multiple characters is allowed.
Column Separator	Select a value from the drop down list. If Other is selected, a new box opens and a new column separator can be entered.
Separator Chars	This field is only available if Column Separator = Other. Allows a custom column separator to be entered. A sequence of multiple characters is allowed.
Excel Template	Optional field, if export file type is Excel Spreadsheet or HTML File, to use an Excel template for data to be exported into. If a Drilldown View has been configured with a specified Excel Template on the input pipe to the File Exporter, setting an Excel Template here will override it. If no Excel Template is specified here, CenterView will check if an Excel Template is specified on the Drilldown View of the pipe. If Export Type is set to "HTML File" and an Excel Template is specified, CenterView will build and output data only for unhidden worksheets in the Excel Template.
Quote Style	Select a value from the drop down list. If Other if selected, a new box opens and a new quote character can be entered.
Quote Character	This field is only available if Quote Style = Other. Allows a custom quote style character to be entered.
Maximum Records per File	This is the maximum number of records that will be written to each file.
Input Multiplier	The input mulitplier expression should evaluate to a list of one or more values. For each value in the list, the internal variable _inputMultiplier will be set to that value and the file export process will be repeated i.e. the pull pipes will be read and the data from those pipes processed to generate file output data, and a new export file will be written.

The following fields are configured through separate tabs on the form:

Field	Description
Description	Description of the file exporter.

Form Icons

The form provides the standard form icons as well as the following:

Shows the model predecessors of the file exporter.

Form: Send Result By Email

On this tab you can set up an automated email to be sent when a file is exported, optionally with the exported file attached.

If an input multiplier expression is provided for this exporter then several files may be produced and each file may be assigned to several recipients. The subject and body expressions may also evaluate to different values each time (for example if _inputMultiplier is included in the expression). In this case CenterView will try to generate as few emails as possible by applying the following rules.

For each recipient identify the files to be sent to that recipient. If the subject and body message calculated for each file is the same then generate a single email and attach all files to that email. If the subject and body messages for each file are different then createone email for each subject and body message pair and attach to each email all the files for which the subject and body expression evaluated to the same subject and body message.

Field	Description
Email From	The Email Address the generated email will appear from.
Subject Expression	Allows the user to build a CenterView Expression which will be used to create the Email Subject.
Attach File	Whether or not the file should be attached to the email sent.
Zip File	This option only appears when the option to Attach File is selected. This specifies whether or not the attached file will be zipped.
Message Expression	Allows the user to build a CenterView Expression which will be used to create the message body of the email.
User Recipients	Tab containing a summary list of each Recipient set up to receive the email.
Recipients Expression	Allows the user to build a CenterView Expression which will be used to calculate the recipients for the email. The recipients returned by this expression will be added to the list of recipients returned by the individual User Notification Rules on the Email Recipients tab. For example to simply enter a list of email addresses you can enter an expression such as: ["john.smith@acme.com","jane.doe@corp.com"] The result of the expression must either be a single string which should be a valid email address or a list object which contains one or more strings, each of which must be a valid email address.

List: User Recipients

Columns

The Recipients list shows a summary of each Recipient set up to receive the email. Selecting a recipient with a double click will bring up the details for that recipient in a User Notification Rule form.

Field	Description
Name	The name of the recipient. This must be a user that has been set up in CenterView.
Email As	Specifies how the email is to be sent to the recipient TO/CC/BCC
Expression	User Notification Rule - the rule that governs whether the email will be sent to this user. See Notification Rule for further details.

List Icons

The Recipient list provides some of the standard list icons. The Recipient list also provides the icons:

	Bring up the list of users configured in CenterView. A user can be selected from this list and dragged into the list of email recipients.
	Add a new Recipient to the recipient list. This will bring up an empty User Notification Rule form.

Form: Set Encryption Parameters

On this tab you can set whether exported files are encrypted, along with the encryption parameters and the password which must then be used to open the files.

Encryption only applies to zipped email attachments.

Field

Description

Encryption Type

The following Encryption Types are supported:

Type	Description
Blank	If the Encryption Type is blank, then the file will not be encrypted.
Standard Zip	Standard ZIP 2.0 encryption is the encryption type that is accepted by most applications, and is the weakest supported encryption type.
AES 128-bit	All variants of AES encryption are stronger than Standard Zip encryption, but AES encryption is accepted by fewer applications. AES 128-bit is the weakest type of AES encryption supported.
AES 192-bit	AES 192-bit.
AES 256-bit	AES 256-bit is the strongest type of AES encryption supported.

Password

The password that must be supplied in order to open any exported zipped files.

When setting the password, you should make a note of the password used and communicate it separately to the recipients of the emails to be sent out. It is not possible to display the current password.

Confirm Password
