The service provides inserting, changing or cancelling of a foreign payment and possibly its check. The two-man rule is provided.
Most payment fields including receiver's account can be changed if payment status is 50 (ready for sending). Only the field User's comment (TEXT) can be changed whenever and it does not yield the two-man rule.
When changing a payment in a state other than 50, all input data, except the User's comment field, are ignored.
