It indicates whether the asset account is free or blocked. There exist 2 blocking types:
- pledged account: instruments from such asset account cannot be moved on another account,
- credit blocking: instruments cannot be moved on such asset account by non-matching transfers (85205/ev205, 85231/ev231, 85264/ev264, 85531/ev531).
In case that the asset account is blocked the transfer is not settled or service is rejected.
