Function Get-AtwsExpenseItem
{


<#
.SYNOPSIS
This function get one or more ExpenseItem 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:
 
ExpenseCategory
  
 
WorkType
  
 
PaymentType
  
 
Entities that have fields that refer to the base entity of this CmdLet:
 
BillingItem
 
.INPUTS
Nothing. This function only takes parameters.
.OUTPUTS
[Autotask.ExpenseItem[]]. This function outputs the Autotask.ExpenseItem that was returned by the API.
.EXAMPLE
Get-AtwsExpenseItem -Id 0
Returns the object with Id 0, if any.
 .EXAMPLE
Get-AtwsExpenseItem -ExpenseItemName SomeName
Returns the object with ExpenseItemName 'SomeName', if any.
 .EXAMPLE
Get-AtwsExpenseItem -ExpenseItemName 'Some Name'
Returns the object with ExpenseItemName 'Some Name', if any.
 .EXAMPLE
Get-AtwsExpenseItem -ExpenseItemName 'Some Name' -NotEquals ExpenseItemName
Returns any objects with a ExpenseItemName that is NOT equal to 'Some Name', if any.
 .EXAMPLE
Get-AtwsExpenseItem -ExpenseItemName SomeName* -Like ExpenseItemName
Returns any object with a ExpenseItemName that matches the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsExpenseItem -ExpenseItemName SomeName* -NotLike ExpenseItemName
Returns any object with a ExpenseItemName that DOES NOT match the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsExpenseItem -ExpenseCategory <PickList Label>
Returns any ExpenseItems with property ExpenseCategory equal to the <PickList Label>. '-PickList' is any parameter on .
 .EXAMPLE
Get-AtwsExpenseItem -ExpenseCategory <PickList Label> -NotEquals ExpenseCategory
Returns any ExpenseItems with property ExpenseCategory NOT equal to the <PickList Label>.
 .EXAMPLE
Get-AtwsExpenseItem -ExpenseCategory <PickList Label1>, <PickList Label2>
Returns any ExpenseItems with property ExpenseCategory equal to EITHER <PickList Label1> OR <PickList Label2>.
 .EXAMPLE
Get-AtwsExpenseItem -ExpenseCategory <PickList Label1>, <PickList Label2> -NotEquals ExpenseCategory
Returns any ExpenseItems with property ExpenseCategory NOT equal to NEITHER <PickList Label1> NOR <PickList Label2>.
 .EXAMPLE
Get-AtwsExpenseItem -Id 1234 -ExpenseItemName SomeName* -ExpenseCategory <PickList Label1>, <PickList Label2> -Like ExpenseItemName -NotEquals ExpenseCategory -GreaterThan Id
An example of a more complex query. This command returns any ExpenseItems with Id GREATER THAN 1234, a ExpenseItemName that matches the simple pattern SomeName* AND that has a ExpenseCategory that is NOT equal to NEITHER <PickList Label1> NOR <PickList Label2>.
