    $reductionCalculator = new ReductionCalculator();
    $reductionCalculator->setClaim($claim);
    $reductionCalculator->setDecreasedCapital($decreasedCapital);
    $reductionCalculator->setCredit($credit);

$form = $this->createForm(ReductionCalculatorType::class);

$form->submit($reductionCalculator);
//or
// $form->setData($reductionCalculator);
