next_receive_date

The next_receive_date attribute is the next contractual date on which cash is expected to be received on the derivative and is a date-time string in ISO 8601 format.

FIRE stores the date of the next incoming cash flow. For related regulatory context, ESMA Guidelines for reporting under EMIR, Section 6.2.2.4.3, Table 84, page 279 records a payment date and receiver separately for notional exchanges. That example does not define a generic next-receipt field.
