# PLSS Schedules Overview

Take noteThis overview explains the Schedules in IMS PLSS. To learn more about Schedules see [IMS Schedules (across Disciplines)](/v414/docs/ims-schedules-across-discipline).

In PLSS, Schedules are created at the Equipment level. A Schedule contains information on:

- *When* to perform an activity.
- *What* to do.
- *How* to do it.

In PLSS four Schedule Types have been implemented. A Schedule can be created for:

- An Inspection (ILI run, collect CP data, …).
- An Assessment (RBA Assessment, Internal Corrosion Assessment, …).
- A Corrective Action (a once-off activity).
- Preventative Maintenance (cleaning pigging, hydrotest, …).

After selecting the Schedule Type, the “What to do” has to be specified by:

- selecting the Scope, for example, **Overland Survey**, **Pigging**, or **Sampling**, ….and,
- selecting the corresponding Plan for that Scope by clicking on **"What is planned?"**  For example, "CP Test Post Survey" is a Plan for the Scope "Overlay Survey".

More information on “How to do” the activity, can be specified in the sections Narrative, Tasks, or Attachments.

So, each Schedule contains:

- A Date, before the Schedule / activity has to be executed.
- A Scope depending on Schedule Type.
- One or more Plan Codes depending on the Scope.
- A Narrative, with a more detailed description of the work.
- Attachments, optional.

After the activity (activities) in the Schedule has been executed, the results will be stored in IMS-PLSS and the Schedule should be credited in the ECH. See [Creating Schedules](/v414/docs/creating-schedules-inspection-cair-and-rbi-re-assessment).

Schedule information can be sent to SAP if the interface to SAP is switched on.

To learn more about Schedules see: [IMS Schedules (across Disciplines)](/v414/docs/ims-schedules-across-discipline).
