Optional
This field specifies the date on which the issuing bank considers the documentary credit as being issued.
Date must be a valid date expressed as YYMMDD (Error code(s): T50).
The absence of this field in an MT 700/701 Issue of a Documentary Credit implies that the date of issue of that documentary credit is the date on which the MT 700/701 was sent.
It is strongly recommended that this field be included in the MT 720.
