I needed to delete all the Managers from people in the FIM Portal where a particular Manager was set. I had blithely assumed this would be easy with the FIM PowerShell plugin – sadly, not so.<\/p>\n

You can clear a string value easily enough by setting it to an empty string. So this works:<\/p>\n
$ImportObject = ModifyImportObject -TargetIdentifier $ID -ObjectType 'Person'\r\nSetSingleValue -ImportObject $ImportObject -AttributeName 'MiddleName' -NewAttributeValue ''\r\nimport-fimconfig -ImportObject $ImportObject<\/pre>\nHowever change that string attribute to a single-valued reference attribute like Manager and you get this helpful error:<\/p>\n
Import-FIMConfig : Failure when making web service call.\r\n\r\nSourceObjectID = guid<\/em>\r\nError = The web service client has encountered the following class of error: Other\r\nDetails: Additional Text Details: Request could not be dispatched.<\/pre>\nNote that I’m only having this problem because my reference attribute is single-valued – for multi you can actually delete any specific value, including the last one, essentially nulling the field. But for single-valued you can’t use the Delete operation – you have to use Replace, and it won’t let you replace it with a null or empty string.<\/p>\n
Eventually I figured out that I could actually delete the value using a workflow with just the OOB Function Evaluator activity. Set the reference attribute to a space (not an empty string for some reason – I had to put a space as the string), run the workflow against the set of people with the Manager I needed to remove, and I got the job done.<\/p>\n
Update:<\/strong> It turns out that setting to a space also works for nulling a Boolean attribute.<\/p>\n","protected":false},"excerpt":{"rendered":"
