Data mapping configurations

A data mapping configuration file contains the information necessary for data mapping: the settings to read the source file (Delimiter and Boundary settings), the data mapping workflow with its extraction instructions ('Steps'), the Data Model and any imported data samples.

Data mapping configurations are used in the Designer to help add variable data fields and personalization scripts to a template. In fact, only a Data Model would suffice (see Importing/exporting a Data Model). The advantage of a data mapping configuration is that it contains the extracted records to merge with the template, which lets you preview a template with data instead of field names.
It is also possible to generate output of a data mapping configuration directly from the Designer (see Generating output).

Ultimately data mapping configurations are meant to be used by the Execute Data Mapping task in Connect Workflow processes, to extract data from a particular type of data file. Typically the extracted data is then merged with a template to generate output in the form of print, email and/or a web page. To make this happen, the data mapping configuration as well as the template and any print presets have to be sent to Workflow; see Sending files to Workflow.

AFP input requires the CDP library. The library licence allows PReS Connect to run up to 4 instances of that library on a given machine at a given time.
Using AFP input in a Server Clustering setup requires you to purchase one additional copy of the library per Server Extension (slave). On each computer you can run up to 4 instances of the CDP library at a given time.

Creating a new data mapping configuration

A new data mapping configuration can be made with or without a wizard. When you open a data file with a DataMapper wizard, the wizard automatically detects a number of settings. You can adjust these settings. Next, the wizard automatically extracts as many data fields (or metadata, in case of a PDF/VT or AFP file) as it can, in one extraction step.
Without a wizard you have to make the settings yourself, and configure the extraction workflow manually.

The DataMapper doesn’t use the data source directly, rather it uses a copy of that data: a data sample. Although the data sample is a copy, it is updated each time the data mapping configuration is opened or whenever the data sample is selected.
More samples can be added via the Settings pane; see Data samples.

From a file

To start creating a data mapping configuration without a wizard, first select the data file. There are two ways to do that: from the Welcome screen and from the File menu.

  • From the Welcome screen
    1. Click Create a New Configuration.
    2. From the From a file pane and select a file type (Comma Separated Values or Excel (CSV/XLSX/XLS), MS-Access, PDF/VT, Text or XML).
    3. Click the Browse button and open the file you want to work with (for a database, you may have to enter a password).
    4. Click Finish.
  • From the File menu
    1. Click the File menu and select New.
    2. Click the Data mapping Configuration drop-down and select Files and then the file type (Comma Separated Values or Excel (CSV/XLSX/XLS), MS-Access, PDF/VT, Text or XML).
    3. Click Next.
    4. Click the Browse button and open the file you want to work with.
    5. Click Finish.
  • Excel files saved in "Strict Open XML" format are not supported yet.
  • PCL and PostScript (PS) files are automatically converted to PDF format. When used in a production environment (a Connect Workflow process) this may influence the processing speed, depending on the available processing power.

After opening the file, you have to make settings for the input data (see Data source settings). Then you can start building the data extraction workflow.

With a wizard

Data mapping wizards are available for PDF/VT, AFP, XML, CSV and database tabular files, because these files are structured in a way that can be used to automatically set record boundaries.
The wizard for PDF/VT and AFP files cannot extract data, only metadata. After opening such a file with the wizard, you can build the data extraction workflow.
The other wizards use the Extract All step to extract data, but they cannot create detail tables, so they are less suitable for files from which you want to extract transactional data.

There are two ways to open a data file with a wizard: from the Welcome screen or from the File menu.

  • From the Welcome screen
    1. Open the PReS ConnectWelcome page by clicking the icon at the top right or select the Help menu and then Welcome.
    2. Click Create a New Configuration.
    3. From the Using a wizard pane, select the appropriate file type.
  • From the File menu
    1. In the menu, click File > New.
    2. Click the Data mapping Wizards drop-down and select the appropriate file type.

The steps to take with the wizard depend on the file type. See:

Generating a counter

Instead of creating a data mapping configuration for a certain type of data file, you may create a data mapping configuration that only contains a series of sequential numbers. This is a solution if, for instance, you need to create sequential tickets or anything that has an ID that changes on each record.

You can’t join this configuration to another data file. It is just a counter to be applied on a static template.

To generate a counter:

  • From the Welcome screen
    1. Open the PReS ConnectWelcome page by clicking the icon at the top right or select the Help menu and then Welcome.
    2. Click Create a New Configuration.
    3. From the Using a wizard pane, select Generate counters.
  • From the File menu
    1. In the menu, click File > New.
    2. Click the Data mapping Wizards drop-down and select Generate counters.

You can set the following parameters:

  • Starting Value: The starting number for the counter. Defaults to 1.
  • Increment Value: The value by which to increment the counter for each record. For example, an increment value of 3 and starting value of 1 would give the counter values of 1, 4, 7, 10, [...]
  • Number of records: The total number of counter records to generate. This is not the end value but rather the total number of actual records to generate.
  • Padding character: Which character to add if the counter's value is smaller than the width.
  • Width: The number of digits the counter will have. If the width is larger than the current counter value, the padding character will be used on the left of the counter value, until the width is equal to the set value. For example for a counter value of "15", a width of "4" and padding character of "0", the value will become "0015".
  • Prefix: String to add before the counter, for example, adding # to get #00001. The prefix length is not counted in the width.
  • Suffix: String to add after the counter. The suffix length is not counted in the width.

Opening a data mapping configuration

To open an existing data mapping configuration, in the Menus, select File > Open. Make sure that the file type is either DataMapper files or Connect files. Browse to the configuration file to open, select it and click Open.
Alternatively, click on File > Open Recent to select one of the recently opened configuration files.

Saving a data mapping configuration

A Data Mapping Configuration file has the extension .OL-datamapper. The file contains the settings, the extraction workflow ('Steps'), the Data Model and the imported Data Samples (excluding database source files such as mySQL, oracle, etc).

To save a data mapping configuration:

  • In the Menus, click on File > Save, or click on Save As to save a copy of a data mapping configuration under a different name.
  • In the Toolbars, click the Save button.

If the data mapping configuration has not been saved before, you have to browse to the location where the data mapping configuration should be saved and type a name, then click Save.
