ECA action for setting initial stock level

Hi,

I solved this problem a few years ago using an arbitrary field to hold the absolute stock level (synchronized from another system using an update migration we run every 15 minutes). I added a presave hook to add a stock level adjustment based on the difference between the stock level and my custom field:

/**
 * Implements hook_ENTITY_TYPE_update().
 */
function mymodule_commerce_product_variation_presave(EntityInterface $entity) {
  // Sync up stock level with last imported MAS stock level
  /** @var \Drupal\commerce_stock\StockServiceManagerInterface $stockManager */
  $stockManager = \Drupal::service('commerce_stock.service_manager');
  $currentLevel = $stockManager->getStockLevel($entity);
  if (round($currentLevel, 3) != round($entity->field_absolute_stock_level->value, 3)) {
    $diff = $entity->field_absolute_stock_level->value - $currentLevel;
    $entity->field_stock_level->setValue($diff);
  }
}

Not sure whether this makes sense to turn into an ECA action...

Hi @freelock, would be awesome to have an ECA action to set the initial stock level. I think it would be useful in a number of scenarios.
Turning this into a feature request.

Maybe something to add to ECA Commerce → ?
