Bulk update objects in FIM/MIM based on CSV file

BulkUpdateFromCsv.ps1

<#
    .SYNOPSIS
        Example script to bulk update users from CSV file.
        The CSV file needs to have columnnames in row 1.
        Columnnames need to correspond to the attribute name in FIM/MIM.
        The column specified as "anchor" will not be updated all other columns will be updated based on content in csv file.
        Multivalue and Reference data types are not supported in this version.
        The script requires that the Lithnet Power Shell module is installed on the computer running the script.
        The account running the script requires write permission to all attributes in the csv file except for the anchor attribute.

Hi @KentNordstrom
I have a multi-valued attribute that needs to be updated through CSV. The single valued are getting updated as you mentioned, but not the MV, can you suggest the change I need to make in the script to accomplish this. Thanks.

Hi @shubhigaur as you can see in the other comments it's not as easy at it looks to make it a "generic" solution. If you have a column with data that needs to go into a MV attribute it will likely be easier to make a version covering your specific scenario.

I have several variants for this depending on the scenario... For example Group.ExplicitMember can be handled from Group perspective adding Persons as members or from Person perspective adding them as members in the listed Group(s).

Thanks Kent, I made the necessary changes in the script, I will post the script here for reference.

PARAM(
[string]$CSVFile = 'C:\Temp\CSVUsers.txt',
[string]$Delimiter = ',',
[string]$Anchor = 'AccountName',
[string]$ResourceType = 'Person',
[string]$FIMServiceURI = 'http://localhost:5725'
)

#region Lithnet
if(!(Get-Module -Name LithnetRMA))
{
Import-Module LithnetRMA;
}

Set-ResourceManagementClient -BaseAddress $FIMServiceURI;
#endregion Lithnet

$Objects = Import-Csv -Delimiter $Delimiter -Path $CSVFile
$Attributes = (Get-Content $CSVFile)[0] -split $Delimiter | ?{$_ -ne $Anchor}

ForEach($Object in $Objects)
{
$resource = Get-Resource -ObjectType $ResourceType -AttributeName $Anchor -AttributeValue ($Object.psobject.Properties | ?{$.Name -eq $Anchor}).Value -AttributesToGet $Attributes
ForEach ($Attribute in $Attributes)
{
if ($resource.MVattribute -eq $null)
{
($resource.psobject.Properties | ?{$.Name -eq $Attribute}).Value = ($Object.psobject.Properties | ?{$.Name -eq $Attribute}).Value
}
else
{
$resource.MVattribute.Add(($Object.psobject.Properties | ?{$.Name -eq $Attribute}).Value)
}
}
$resource | Save-Resource
}

@shubhigaur Do you have a small sample csv file that works with your version of the script? Just for reference if people find this Gist.

ADDN:OUMapping
OU=00001,OU=Branches,DC=LO,DC=AD,DC=UAT:Oxford Branch
OU=00002,OU=Branches,DC=LO,DC=AD,DC=UAT:ABCD Branch
OU=00003,OU=Branches,DC=LO,DC=AD,DC=UAT:MI Branch
OU=00003,OU=Branches,DC=LO,DC=AD,DC=UAT:COD Branch
OU=00004,OU=Branches,DC=LO,DC=AD,DC=UAT:NO Branch
OU=00004,OU=Branches,DC=LO,DC=AD,DC=UAT:CSO Branch

I am mapping ADDN with a branch name here. 00003 and 0004 has multiple values and OUMapping is a MV attribute here
