Function Get-AtwsServiceCall
{


<#
.SYNOPSIS
This function get one or more ServiceCall 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:

Status
 

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

ServiceCallTask
 ServiceCallTicket

.INPUTS
Nothing. This function only takes parameters.
.OUTPUTS
[Autotask.ServiceCall[]]. This function outputs the Autotask.ServiceCall that was returned by the API.
.EXAMPLE
Get-AtwsServiceCall -Id 0
Returns the object with Id 0, if any.
 .EXAMPLE
Get-AtwsServiceCall -ServiceCallName SomeName
Returns the object with ServiceCallName 'SomeName', if any.
 .EXAMPLE
Get-AtwsServiceCall -ServiceCallName 'Some Name'
Returns the object with ServiceCallName 'Some Name', if any.
 .EXAMPLE
Get-AtwsServiceCall -ServiceCallName 'Some Name' -NotEquals ServiceCallName
Returns any objects with a ServiceCallName that is NOT equal to 'Some Name', if any.
 .EXAMPLE
Get-AtwsServiceCall -ServiceCallName SomeName* -Like ServiceCallName
Returns any object with a ServiceCallName that matches the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsServiceCall -ServiceCallName SomeName* -NotLike ServiceCallName
Returns any object with a ServiceCallName that DOES NOT match the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsServiceCall -S <PickList Label>
Returns any ServiceCalls with property S equal to the <PickList Label>. '-PickList' is any parameter on .
 .EXAMPLE
Get-AtwsServiceCall -S <PickList Label> -NotEquals S
Returns any ServiceCalls with property S NOT equal to the <PickList Label>.
 .EXAMPLE
Get-AtwsServiceCall -S <PickList Label1>, <PickList Label2>
Returns any ServiceCalls with property S equal to EITHER <PickList Label1> OR <PickList Label2>.
 .EXAMPLE
Get-AtwsServiceCall -S <PickList Label1>, <PickList Label2> -NotEquals S
Returns any ServiceCalls with property S NOT equal to NEITHER <PickList Label1> NOR <PickList Label2>.
 .EXAMPLE
Get-AtwsServiceCall -Id 1234 -ServiceCallName SomeName* -S <PickList Label1>, <PickList Label2> -Like ServiceCallName -NotEquals S -GreaterThan Id
An example of a more complex query. This command returns any ServiceCalls with Id GREATER THAN 1234, a ServiceCallName that matches the simple pattern SomeName* AND that has a S that is NOT equal to NEITHER <PickList Label1> NOR <PickList Label2>.
