Question

I have a transaction where I am inserting a new record into TableB and depending if there is not the proper supporting record in TableA I will also be inserting into TableA and using that Primary Key as a Foreign key entry into TableB.

$transaction=$connection->beginTransaction();
try 
{
    $tableA->IsActive = 'Y'; 
    $tableA->save();

    $model->TableAId = $tableA->TableAId;  //not sure what to put here for $tableA->TableAId
    $model->save();

    $transaction->commit(); 
}

In this situation can I use Yii::app()->db->getLastInsertId(); for $tableA->TableAId;

Obviously accuracy is highly important here so I need to guarantee that the proper records align between TableA and TableB

Basically, Your comment looks perfect. $model->TableAId = $tableA->TableAId; // This is perfect!!
But code not. Following should be your code.

$transaction=$connection->beginTransaction();
try 
{
    $tableA = TableA::model()->findByPk("id"); OR $tableA = new TableA;
    $tableA->IsActive = 'Y'; 
    $tableA->save();

    $model = new TableB;
    $model->TableAId = $tableA->TableAId;  //not sure what to put here for $tableA->TableAId // This is perfect!!
    $model->save();

    $transaction->commit(); 
}
