ADID and IA arguments identify an occurrence, OPNO identifies an occurrence operation.

The predecessor application is identified by PREADID, its occurrence by PREIA, and its operation by PREOPNO. If the predecessor is mandatory, set PREMAND to Y (the default is N).

The operands ADID and OPNO are mandatory. The PREOPNO argument is required only for an operation that depends on another operation. PREADID is mandatory if the predecessor is external.

The input arrival date and time is mandatory information, but it can be supplied in different ways:
  1. Specifying IA in the normal way.
  2. Specifying IA by entering 'YYMMDD' in place of the first six characters; the code will substitute them with the current date.
  3. Specifying IAD and IAT separately.
  4. Specifying only IAT; in which case the code will take the current date as the default for IAD.
If IA is omitted, then at least IAT is mandatory. The predecessor input arrival date and time is mandatory information only when there is an external predecessor. Also in this case it can be entered in different ways:
  1. Specifying PREIA in the normal way.
  2. Specifying PREIA by entering 'YYMMDD' in place of the first six characters; the code will substitute them with the current date.
  3. Specifying PREIAD and PREIAT separately.
  4. Specifying only PREIAT; in which case the code will take the current date as the default for PREIAD.

If PREIA is omitted and it is an external predecessor, then at least PREIAT is mandatory.
