Mapping variables in transformations in Jitterbit Integration Studio

Introduction

Variables can be mapped to a target field in either mapping mode or script mode. When you map a variable, the variable reference is inserted into a script on the target field. Variable references are constructed with a dollar sign ($) preceding the variable name. For information on creating, configuring, and using variables, see Variables.

Access variables for mapping

In mapping mode, existing variables are listed by type within the Variables tab on the source side of the transformation:

variables

Within the list, the type of each variable is indicated by the icon next to the name:

  • global variable for global variable
  • project variable for project variable
  • Jitterbit variable for Jitterbit variable

The icon's background is solid if the variable has a default value, or empty project variable if it does not.

In script mode, existing variables are listed within the Variables tab of the script component palette in sub-tabs for each type:

project variables

Both modes have a search box where you can enter a keyword or keywords separated by commas. Variables that have any part of the keywords in their name are returned.

Project, global, and Jitterbit variables are available to use in the transformation:

  • Project Variables: Project variables that have already been created and are available to use globally within the project. To create or edit a new project variable:

    • Mapping Mode: To create a new project variable, click Create New Project Variable, or to edit an existing project variable, hover over the variable and click the edit icon.

    • Script Mode: To create a new project variable, click Add New, or to edit an existing project variable, click the name of the variable.

  • Global Variables: Global variables that have been defined anywhere in the project.

    Warning

    Global variables should be declared upstream of the transformation to be used within the transformation. If the global variable has not been initialized, the default value for a global variable is empty.

  • Jitterbit Variables: Jitterbit variables that are available to use globally within the project.

    Caution

    Some Jitterbit variables that are listed may not be applicable to the specific operation. Refer to the documentation on each variable under Jitterbit variables.

Map to a target field

Variables can be mapped by dragging and dropping, double-clicking, or manually inserting the variable's reference path:

  • Drag-and-drop: Dragging and dropping variables can be done in mapping mode and script mode:

    • Mapping mode: Within the Variables tab on the left, drag a variable on the left to an appropriate target field on the right:

      drop variable annotated pp

    • Script mode: Within the Variables tab on the right, drag a variable on the right to an appropriate target field on the left:

      drop variable annotated pp

  • Double-click: In script mode, double-click the variable in the Variables tab to insert the variable's reference at your cursor's location within the script.

  • Manual insertion: You can open an editable script area to manually enter variable references from either mapping mode or script mode. To add a new script on a target field, do one of the following:

    • Double-click the field name.

    • Hover over the target field and click the add icon in the upper right to open a menu of actions. From the menu select Add Script:

      target field add script

A referenced variable is visually displayed within the mapped target field, with a script icon added in the top right to indicate the field has a mapping:

target field variable

To view or edit the mapping as a script, double-click the field name or click the script icon to open the editable script area for the target field in script mode:

Map to a field with an existing mapping

When dragging and dropping a variable to a target field that already has a mapping, you are presented with the option to copy the variable reference to your clipboard so that you can manually paste that reference into the script logic:

add project variable to script

On clicking Continue, the target field becomes expanded with an editable script area for you to paste in the variable reference in script mode. For mappings that contain multiple references, you must then add scripting logic to make the script valid. For example:

variable source object

When adding additional variable references by double-clicking or manual insertion, the dialog for copying a variable reference is not presented. However, you can add multiple variable references into the editable script area by double-clicking, dragging and dropping, or manually inserting the references.

Edit or remove a mapping

While in mapping mode or script mode, you can edit or remove target field mappings one at a time or remove all field mappings contained within a node:
