Load Variable Data

This action loads values of a single or multiple variables from the associated data file as saved by the action Save Variable Data. Use this action to exchange the data between triggers. You can load a particular variable or all variables that are stored in the data file.

About group identifies the selected action.

  • Name: allows you to define a custom action name. This makes actions easily recognizable on the solution's list of actions. By default, the action name is taken from its type.
  • Description: custom information about the action. Enter a description to explain the purpose and role of action in a solution.
  • Action type: read-only information about the selected action type.

Settings group defines the file name.

  • File name: specifies the file for the variable data to be loaded from. If the name is hard-coded, the values are loaded from the same file each time.

    Use UNC syntax for network resources. For more information, see section Access to Network Shared Resources in Loftware Automation user guide.

File Structure group settings must reflect the structure of the saved file from the Save Variable Data action.

  • Delimiter: specifies delimiter type (tab, semicolon, comma or custom character). Delimiter is a character that separates the values.

  • Text qualifier: specifies the character that qualifies content as text.

  • File encoding: specifies the character encoding type used in the data file. Auto defines the encoding automatically. If needed, select the preferred encoding type from the drop-down list.

    Tip

    UTF-8 makes a good default selection.

Variables group defines the variables whose values should be loaded from the data file.

  • All variables: specifies all defined variables in the data file to be read.

  • Selected variables: specifies selection of individual variables to be read from the data file.

Action Execution and Error Handling

Each action can be set as a conditional action. Conditional actions only run when the defined conditions allow them to be run. To define these conditions, click Show execution and error handling options.

Execution options are:

  • Enabled: specifies if the action is enabled or disabled. Only enabled actions will execute. This functionality may be used while testing a form.
  • Condition: defines one-line programming expression that must provide a Boolean value (true or false). When the result of the expression is true, the action will execute. Condition offers a way to avoid executing actions every time.

Error handling options are:

  • Ignore failure: specifies whether an error should be ignored. If enabled, the execution of actions continues even if the current action fails.

    Note

    Nested actions that depend on the current action do not execute in case of a failure. The execution of actions continues with the next action on the same level as the current action. The error is logged but does not break the execution of the action.

    • Example

    At the end of printing, you might want to send the status update to an external application using the HTTP Request action. If the printing action fails, action processing stops. In order to execute the reporting even after the failed print action, the Print Label action must have the option Ignore failure enabled.

  • Save error to variable: allows you to select or create a variable to save the error to. The same cause of the error is also saved to internal variables ActionLastErrorId and ActionLastErrorDesc.
