PCS constraints overview

Content

The aim of this document is to give an overview to PCS GUI users and integrators about the constraints that are applied by the system during the daily business with the dossiers. We tried to collect here the fields that are mandatory in PCS and some rules that are applied during dossier creation, dossier editing and dossier processing (change of acceptance indicator and promotion). We also tried to cluster the different constraints, mandatory fields. As this is a summary of the constraints we made some references to the original documentation where you may find more details.

Basic Data

  • Dossier name is a mandatory field of PCS

Agencies

  • There must be always one Applicant marked as leading Applicant
  • There must be always one IM marked as leading IM
  • Each agency (Applicant or IM) must be responsible for at least two path sections (territory has at least one subpath that has at least two path sections)
  • Production-only agencies have read-only access to the dossier. If an Applicant is presented in the timetable as production-only, it will have read-only access to the dossier.

Paths

  • Each subpath must have at least two path sections
  • Involved Applicant/IM cannot update/delete anything outside of its responsibility via GUI neither via PCS IP

Reference points/Construction starting point

  • The reference point is assigned by the system automatically to the first path section
  • The mandatory departure time must be entered at the reference point
  • An involved applicant can indicate with the gear icon which path section shall be considered as a construction starting point. One subpath can have maximum one construction starting point. It has no impact on the calendar, timetable, offsets.

Calendar constraints

  • Reference calendars of the subpath most cover the same days that are coming from the previous territory. EXCEPTION: if the territory has an alternative origin, or the previous territory has an alternative destination, the territory can have more or less running days than the previous territory.
