public void DeleteResources(
    Guid[] arrayRes,
    string deletionComment
)

Parameters

  • arrayRes
    Type: []
    Guids of the resources to delete.
  • deletionComment
    Type: System.String
    A brief note describing the deletion. This comment is sent to any affected project manager when a resource in their project changes from an enterprise resource to a local resource.

Remarks

The resource must be checked out before it can be deleted.

A resource may not be deleted if the resource:

  • Has anything checked out

  • Is the current user

  • Owns a project

  • Is a timesheet manager

  • Owns an assignment

  • Is the default assignment owner

  • Is used in a resource plan

Project Server Permissions

Permission

Description

CleanupProjectServerDatabase

Allows a user to delete information from the database. Global permission.

Examples

The following example creates several resources, retrieving them if they already exist, reports them, and then deletes them.
