How to fix this issue

Your data is missing a plan.

The plan timetable guidance explains how to fix the issue:

plan

This is the unique reference for your overall plan. For example:

  • LP-BRX-2024
  • barnet-local-plan-2021-2036
  • hertfordshire-minerals-and-waste-plan
  • essex-minerals-plan
  • essex-waste-plan
  • county-durham-supplementary-plan

The ‘plan’ field in your plan timetable dataset must match the ‘reference’ field from your plan dataset.

This diagram shows the relationship between the plan dataset and the plan timetable dataset. The reference value from your plan dataset needs to match the plan value in your plan timetable dataset. This is so that we can match your timetable to the right plan.
