Function New-AtwsTask
{


<#
.SYNOPSIS
This function creates a new Task through the Autotask Web Services API. All required properties are marked as required parameters to assist you on the command line.
.DESCRIPTION
The function supports all properties of an [Autotask.Task] that can be updated through the Web Services API. The function uses PowerShell parameter validation and supports IntelliSense for selecting picklist values. Any required paramterer is marked as Mandatory in the PowerShell function to assist you on the command line.

If you need very complicated queries you can write a filter directly and pass it using the -Filter parameter. To get the Task with Id number 0 you could write 'New-AtwsTask -Id 0' or you could write 'New-AtwsTask -Filter {Id -eq 0}.

'New-AtwsTask -Id 0,4' could be written as 'New-AtwsTask -Filter {id -eq 0 -or id -eq 4}'. For simple queries you can see that using parameters is much easier than the -Filter option. But the -Filter option supports an arbitrary sequence of most operators (-eq, -ne, -gt, -ge, -lt, -le, -and, -or, -beginswith, -endswith, -contains, -like, -notlike, -soundslike, -isnotnull, -isnull, -isthisday). As you can group them using parenthesis '()' you can write arbitrarily complex queries with -Filter.

To create a new Task you need the following required fields:
 -ProjectID
 -Title
 -TaskType
 -Status

Entities that have fields that refer to the base entity of this CmdLet:


.INPUTS
Nothing. This function only takes parameters.
.OUTPUTS
[Autotask.Task]. This function outputs the Autotask.Task that was created by the API.
.EXAMPLE
$result = New-AtwsTask -ProjectID [Value] -Title [Value] -TaskType [Value] -Status [Value]
Creates a new [Autotask.Task] through the Web Services API and returns the new object.
 .EXAMPLE
$result = Get-AtwsTask -Id 124 | New-AtwsTask
Copies [Autotask.Task] by Id 124 to a new object through the Web Services API and returns the new object.
 .EXAMPLE
Get-AtwsTask -Id 124 | New-AtwsTask | Set-AtwsTask -ParameterName 'Parameter Value'
Copies [Autotask.Task] by Id 124 to a new object through the Web Services API, passes the new object to the Set-AtwsTask to modify the object.
 .EXAMPLE
$result = Get-AtwsTask -Id 124 | New-AtwsTask | Set-AtwsTask -ParameterName 'Parameter Value' -Passthru
Copies [Autotask.Task] by Id 124 to a new object through the Web Services API, passes the new object to the Set-AtwsTask to modify the object and returns the new object.
