Function Get-AtwsTimeEntry
{


<#
.SYNOPSIS
This function get one or more TimeEntry through the Autotask Web Services API.
.DESCRIPTION
This function creates a query based on any parameters you give and returns any resulting objects from the Autotask Web Services Api. By default the function returns any objects with properties that are Equal (-eq) to the value of the parameter. To give you more flexibility you can modify the operator by using -NotEquals [ParameterName[]], -LessThan [ParameterName[]] and so on.
 
Possible operators for all parameters are:
 -NotEquals
 -GreaterThan
 -GreaterThanOrEqual
 -LessThan
 -LessThanOrEquals
 
Additional operators for [String] parameters are:
 -Like (supports * or % as wildcards)
 -NotLike
 -BeginsWith
 -EndsWith
 -Contains
 
Properties with picklists are:
 
Type
  
 
Entities that have fields that refer to the base entity of this CmdLet:
 
BillingItem
 BillingItemApprovalLevel
 NotificationHistory
 
.INPUTS
Nothing. This function only takes parameters.
.OUTPUTS
[Autotask.TimeEntry[]]. This function outputs the Autotask.TimeEntry that was returned by the API.
.EXAMPLE
Get-AtwsTimeEntry -Id 0
Returns the object with Id 0, if any.
 .EXAMPLE
Get-AtwsTimeEntry -TimeEntryName SomeName
Returns the object with TimeEntryName 'SomeName', if any.
 .EXAMPLE
Get-AtwsTimeEntry -TimeEntryName 'Some Name'
Returns the object with TimeEntryName 'Some Name', if any.
 .EXAMPLE
Get-AtwsTimeEntry -TimeEntryName 'Some Name' -NotEquals TimeEntryName
Returns any objects with a TimeEntryName that is NOT equal to 'Some Name', if any.
 .EXAMPLE
Get-AtwsTimeEntry -TimeEntryName SomeName* -Like TimeEntryName
Returns any object with a TimeEntryName that matches the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsTimeEntry -TimeEntryName SomeName* -NotLike TimeEntryName
Returns any object with a TimeEntryName that DOES NOT match the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsTimeEntry -T <PickList Label>
Returns any TimeEntrys with property T equal to the <PickList Label>. '-PickList' is any parameter on .
 .EXAMPLE
Get-AtwsTimeEntry -T <PickList Label> -NotEquals T
Returns any TimeEntrys with property T NOT equal to the <PickList Label>.
 .EXAMPLE
Get-AtwsTimeEntry -T <PickList Label1>, <PickList Label2>
Returns any TimeEntrys with property T equal to EITHER <PickList Label1> OR <PickList Label2>.
 .EXAMPLE
Get-AtwsTimeEntry -T <PickList Label1>, <PickList Label2> -NotEquals T
Returns any TimeEntrys with property T NOT equal to NEITHER <PickList Label1> NOR <PickList Label2>.
 .EXAMPLE
Get-AtwsTimeEntry -Id 1234 -TimeEntryName SomeName* -T <PickList Label1>, <PickList Label2> -Like TimeEntryName -NotEquals T -GreaterThan Id
An example of a more complex query. This command returns any TimeEntrys with Id GREATER THAN 1234, a TimeEntryName that matches the simple pattern SomeName* AND that has a T that is NOT equal to NEITHER <PickList Label1> NOR <PickList Label2>.
