title: Finding how to populate a field in Powershell with JiraPS
body: <p>So, i'm using JiraPS to create some tickets and so far i've been able to work out through trial and error how to populate certain standard and custom fields.</p>
  <p>I'm now wanting to create a ticket and link to other tickets. I'm looking to use a standard field called &quot;Linked Issues&quot;</p>
  <p><a href="https://i.stack.imgur.com/lYXni.png" rel="nofollow noreferrer">Linked Issues Screen Shot</a></p>
  <p>I've exported all the Jira fields and think this is one of these fields:</p>
  <p>ID          : issuelinks
  Searchable  : True
  Schema      : @{type=array; items=issuelinks; system=issuelinks}
  Name        : Linked Issues
  Custom      : False
  Navigable   : True
  Orderable   : True
  ClauseNames :</p>
  <p>and possibly &quot;subtasks&quot; for the issues field:</p>
  <p>ID          : subtasks
  Searchable  : False
  Schema      : @{type=array; items=issuelinks; system=subtasks}
  Name        : Sub-Tasks
  Custom      : False
  Navigable   : True
  Orderable   : False
  ClauseNames : subtasks</p>
  <p>I only think this as &quot;items&quot; match issuelinks.</p>
  <p>I note that these are array records and have tried to no avail to give them a value when creating a ticket.</p>
  <p>I get these errors:</p>
  <p>Invoke-JiraMethod:  subtasks -------- Field 'subtasks' cannot be set. It is not on the appropriate screen, or unknown.</p>
  <p>nvoke-JiraMethod:  issuelinks ---------- Field does not support update 'issuelinks'</p>
  <p>If anyone has any ideas if I'm on the right track or way off!</p>
  <p>Thanks</p>
