useful when you need to run several tasks (DL, CFS, CF, ...) in a sequence (so that they wait for each other).

Control Table

SequenceName	Order	Type	TaskName	State
DM X load	1	DL	SalesDFtoDS	/ RUNNING / DONE / ERROR
DM X load	2	DL	SalesDStoDM
DM X load	3	DL	SalesDMCalculation

SequenceName - you can have more sequences. All tasks which should run in one sequence must have the same SequenceName
Order - this is used to execute the tasks in correct order. When 2 or more tasks in the sequence have the same OrderOfTask number, then they will be run in parallel.
Type - what should be executed
TaskName - the name of the DL / CFS / ...
State - what is happening with the task.
- <nothing> - should be executed
- RUNNING - is running now
- DONE - finished successfully
- ERROR - finished with ERROR (is the task ends with ERROR, it stops the sequence)
LastRun - datetime of the end of last run of the task

Scheduler

is simple CFF, which is executed every minute and starts the tasks according the Control Table

Groovy Library - add a new element called "Sequencer", with following code: Sequencer Library Code.groovy
New Calculation Flow Formula, scheduled every minute, with one element with this code:
```
lib.Sequencer.processAllSequences(actionBuilder)
```
Import the Price Parameter called SequenceControlTable - the import zip file is attached here PP_SequenceControlTable_for_Import.zip

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

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