theoretically yes. In this rule you those arguments:
<Argument name="certification">
<Description>
The sailpoint.object.Certification being certified.
</Description>
</Argument>
<Argument name="certificationItem">
<Description>
The sailpoint.object.CertificationItem that is being certified.
</Description>
</Argument>
<Argument name="previousPhase">
<Description>
Certification.Phase (may be null) that is the previous phase.
</Description>
</Argument>
<Argument name="nextPhase">
<Description>
Certification.Phase (may be null) that is the next phase.
</Description>
</Argument>
so you change the status of certification object with setComplete(false) for example
My requirement: Certification should be show the percentage item completed field as 0 or certification completed status as false those who are not taken any action during the certification period.
i have tried the following code through certification automatic closing rule but still my requirement is not achieved.
I do not think after closure you can keep line item open. May be once it is closed then you can force it to remain open after reading it from rule and modifying, but this is also just guessed.
On second thought you may update some specific comment from the rule just if you want to track where no action was taken, and it has been close automatically.
