Remove workflow column from SharePoint List

I am going to describe how to delete unwanted or orphaned workflow column from a List.it can be done simply by writing few lines of powershell command as below.

 

function Delete-WorkflowColumn ($webURL, $listName, $columnName)
 {
 #Setup variables from the user input
 $web = Get-SPWeb $webURL
 $list = $web.Lists[$listName]
 $column = $list.Fields[$columnName]
#Make sure the column is not hidden or read only
 $column.Hidden = $false
$column.ReadOnlyField = $false
$column.Update()
#Delete column and dispose of the web object
$list.Fields.Delete($column)
write-host "Deleted column"
$web.Dispose()
}


Delete-WorkflowColumn -webURL http://ServerName/ -listName "ERP Request" -columnName

"Approval Workflow"

 

 

 save above notepad with the name of delete.ps1 and then from powershellscript do as below

PS D:\> .\delete.ps1
 Deleted column
 PS D:\>
