Function Get-AtwsInstalledProduct
{


<#
.SYNOPSIS
This function get one or more InstalledProduct 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
  
 
ServiceLevelAgreementID
  
 
RMMDeviceAuditArchitectureID
  
 
RMMDeviceAuditDisplayAdaptorID
  
 
RMMDeviceAuditDomainID
  
 
RMMDeviceAuditManufacturerID
  
 
RMMDeviceAuditModelID
  
 
RMMDeviceAuditMotherboardID
  
 
RMMDeviceAuditProcessorID
  
 
RMMDeviceAuditServicePackID
  
 
RMMDeviceAuditDeviceTypeID
  
 
RMMDeviceAuditMobileNetworkOperatorID
  
 
DattoOSVersionID
  
 
DattoZFSVersionID
  
 
DattoKernelVersionID
  
 
RMMDeviceAuditAntivirusStatusID
  
 
RMMDeviceAuditBackupStatusID
  
 
RMMDeviceAuditPatchStatusID
  
 
RMMDeviceAuditSoftwareStatusID
  
 
LastActivityPersonType
  
 
Entities that have fields that refer to the base entity of this CmdLet:
 
BillingItem
 InstalledProduct
 Subscription
 Ticket
 TicketAdditionalInstalledProduct
 
.INPUTS
Nothing. This function only takes parameters.
.OUTPUTS
[Autotask.InstalledProduct[]]. This function outputs the Autotask.InstalledProduct that was returned by the API.
.EXAMPLE
Get-AtwsInstalledProduct -Id 0
Returns the object with Id 0, if any.
 .EXAMPLE
Get-AtwsInstalledProduct -InstalledProductName SomeName
Returns the object with InstalledProductName 'SomeName', if any.
 .EXAMPLE
Get-AtwsInstalledProduct -InstalledProductName 'Some Name'
Returns the object with InstalledProductName 'Some Name', if any.
 .EXAMPLE
Get-AtwsInstalledProduct -InstalledProductName 'Some Name' -NotEquals InstalledProductName
Returns any objects with a InstalledProductName that is NOT equal to 'Some Name', if any.
 .EXAMPLE
Get-AtwsInstalledProduct -InstalledProductName SomeName* -Like InstalledProductName
Returns any object with a InstalledProductName that matches the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsInstalledProduct -InstalledProductName SomeName* -NotLike InstalledProductName
Returns any object with a InstalledProductName that DOES NOT match the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsInstalledProduct -Type <PickList Label>
Returns any InstalledProducts with property Type equal to the <PickList Label>. '-PickList' is any parameter on .
 .EXAMPLE
Get-AtwsInstalledProduct -Type <PickList Label> -NotEquals Type
Returns any InstalledProducts with property Type NOT equal to the <PickList Label>.
 .EXAMPLE
Get-AtwsInstalledProduct -Type <PickList Label1>, <PickList Label2>
Returns any InstalledProducts with property Type equal to EITHER <PickList Label1> OR <PickList Label2>.
 .EXAMPLE
Get-AtwsInstalledProduct -Type <PickList Label1>, <PickList Label2> -NotEquals Type
Returns any InstalledProducts with property Type NOT equal to NEITHER <PickList Label1> NOR <PickList Label2>.
 .EXAMPLE
Get-AtwsInstalledProduct -Id 1234 -InstalledProductName SomeName* -Type <PickList Label1>, <PickList Label2> -Like InstalledProductName -NotEquals Type -GreaterThan Id
An example of a more complex query. This command returns any InstalledProducts with Id GREATER THAN 1234, a InstalledProductName that matches the simple pattern SomeName* AND that has a Type that is NOT equal to NEITHER <PickList Label1> NOR <PickList Label2>.
