Remove Defect from Iteration ClearQuest API

Question

There can multiple defects attached to an iteration.How can I remove a particular defect from iteration using ClearQuest Perl API?

$bfSession = CQSession::Build();
$bfSession->UserLogon($userID,$passwd,$dbname,$dbset);

#Get iteration Entity
$iterationEntity = $bfSession->GetEntity("tmiteration", $iteration);

#Now to add defect to Iteration i can do the following
$bfSession->EditEntity($iterationEntity, "modify");
$result = $iterationEntity->AddFieldValue("Defects", $defect);
$valResult = $iterationEntity->Validate();

if($valResult eq "")
    {
        $iterationEntity->Commit();
    }
    else
    {
        $iterationEntity->Revert();
    }

Just like AddFieldValue Is there is any API to remove defects from iteration?

EDIT: I was not able to find such API in IBM ClearQuest documention

Answer 1

We can use DeleteFieldValue API to Remove Child records from parent records.

$bfSession->EditEntity($IterationEntity, "modify");
$result = $IterationEntity->DeleteFieldValue("Defects", $defectId);
