BPM Processes: Cron | X4Documentation

The Cron button can be used to create new configurations for server startup executions. A number of options and parameters are available. These are explained in more detail below.

Options

Name	Freely selectable name for the execution
Process	Path to the process in the `X4DB` Example: `Processes/Activities/Processes/Process.wrf` Select Browse or drag and drop a process into the field to select a process. The process must be in the same project as the scheduler. The process must not be a subprocess of another process.
Active	Enables the scheduler.
Generate Cron Expression	Creates a Cron expression. Possible values: `Minutes` `Hourly` `Daily` `Weekly` `Monthly` `Yearly` In the Source tab, you can manually edit the Cron expression. It is not possible to generate a Cron expression if the Cron expression has been manually edited.

Parameters

In the Parameters section, you can define any number of parameters for the execution configuration.

	Add a row
	Delete a row
Key	Name of the parameter (any string, ideally `NCName`)
Value	Optional parameter value

The scheduler creates an XML file as input for the process, which contains the defined parameters. The input XML file is loaded directly into the process at the start block.

Since the parameter values are only directly accessible at the start of the process, they must be saved (e.g. as a variable) if they are to be used later in the process.

Example:

XML

<?xml version="1.0" encoding="UTF-8"?>
<Execution jobId="JobId" executionId="ExecutionId" executionName="ExecutionName">
  <Parameters>
    <Parameter name="ParameterKey">ParameterValue</Parameter>
    <Parameter name="ParameterKey">ParameterValue</Parameter>
    <Parameter name="ParameterKey">ParameterValue</Parameter>
    ...
  </Parameters>
</Execution>
