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. Using that we can usually create a task list, but the bad thing is the task name will allow duplicate values. To avoid that we need a field which will enforce unique name for task.

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.
