The following function is useful when you need to run several tasks (Data Loads, Calculated Field Sets, Calculation Flows,...) in a sequence and ensure that they wait for each other.

Control Table

• SequenceName – You can have more sequences. All tasks which should run in one sequence must have the same SequenceName.
• Order – Sets the order in which the tasks should be executed. When two or more tasks in the sequence have the same OrderOfTask number, they will run in parallel.
• Type – Determines what should be executed.
• TaskName – Defines the name of the DL, CFS etc.
• State – Informs about the task.
  • <no value> – Execution pending.
  • RUNNING – Execution in progress.
  • DONE – Execution finished successfully.
  •  ERROR – Execution finished with an error (if a task ends with an error, the sequence stops).
• LastRun – Shows when the last run of the task ended.

Scheduler

Scheduler is a simple Calculation Flow Formula which is executed every minute and starts the tasks according to the Control Table. 

Installation

1. In Groovy Library, add a new element called "Sequencer" with the following code: Sequencer Library Code.groovy

2. Create a new Calculation Flow Formula, scheduled for every minute, with one element with this code: 

   lib.Sequencer.processAllSequences(actionBuilder)

3. Import the Price Parameter called "SequenceControlTable". The import ZIP file is attached: PP_SequenceControlTable_for_Import.zip

Running Your Own Sequence

From your code (usually from a CFF but generally from any code which is allowed to modify Price Parameters) call the following:

lib.Sequencer.startSequence("<your sequence name>")
