Time Consistency Business Rules
Find below a description of restrictions on the sequence of Timestamp type attributes. Time consistency rules apply for combined contracts for each level separately.
CDD <= IED <= XX <= OPXED <= MD <= AMD <= STD
where XX are IPCED, PRD, TD, plus all anchor dates (e.g. RRANX) except IPANX
CDD <= SD <= XX
where XX are any of MD, STD, OPXED and TD
If DVNP defined and DVCL not defined, then DVANX > SD (because DVANX defines the date of payment of DVNP).
