How To Avoid Duplicate Values In Task List And Make Another Field As Title Field In SharePoint 2013

In SharePoint 2013, we have Task Content type that allows us creating a task list. The bad thing about the Task Content Type is that it allows duplicate values as Task names. To avoid that, we need a field which exactly will work like task name or Title field.

For that, you need to create a new column and name it as: "Task”. Then, enforce unique values in the Task column.

However, it will still have issues such as - it will miss the feature to link to edit item, link to view item, and add to time line. To enable those features to the column, we can use a small PowerShell script given below.

Add-PSSnapin "Microsoft.SharePoint.PowerShell"
#Get the web
$SourceWebURL = "http://klmn/sites/rst/";
$Spweb = Get-SPWeb $SourceWebURL;
#update based on your list
$ListName="TaskList1";
$FieldName="Task";
$SPList = $Spweb.Lists[$ListName];
$field=$SPList.Fields[$FieldName];
$field.ListItemMenu = $true;
$field.ListItemMenuAllowed = 1;
$field.Update();
$SPList.Update();

Fig 1: Both, Task field and Tile field, are showing all the same features but the Task field enforces unique values.
