IdentityManager.PoSh

Do you mean a parameter set in the parameter collection and used by $PC(ParameterName)$ in the process?

Let's assume you want to specify parameters for the parameter collection (as mentioned above).

Then you can use the cmdlet parameter EventParameters to specify a hashtable with your additional parameters. (https://github.com/OneIdentity/IdentityManager.PoSh)

Trigger an event for an entity

After you know the name for the event to trigger, you can fire it like:

Invoke-ImEvent -Entity $p1 -EventName "CHECK_EXITDATE"

It's possible to pass certain event parameters if needed. Use EventParameters as hash table for that.

A sample code would look like the following:

# Specify the parameters in a hash  table
$myParameters = @{myparametername1 = "myvalue1"; myparametername2 = "myvalue2"}

# Trigger an event for an entity with your additional parameters
Invoke-IMEvent -Entity $myentity -EventName "Name of the event" -EventParameters $myParameters

okay, I think I have misunderstood the concept of Invoke-ImEvent cmdlet. 

I was trying to run ADSAccount update event with some value i.e Surname while having a gen condition FULLSYNC = FALSE and CUSTOMVARIABLE = TRUE. 

So now, instead of running Invoke-ImEvent I've ran SET cmdlet with session variables.

Sample code:

# Get the session
$sessionToUse = $Global:imsessions[$Global:imsessions.Keys[0]].Session

# Add variable

$sessionToUse.Variables.Put('FULLSYNC', $false)
$sessionToUse.Variables.Put('CUSTOMVARIABLE', $true)

# Query a variable
$sessionToUse.Variables['FULLSYNC']
$sessionToUse.Variables['CUSTOMVARIABLE']

# Run Command
Set-Entity -Type ADSAccount -Identity "6h27ef73-a13f-40eb-a7a3-2f49e487e5g2" -Properties @{'Surname' = 'Schmidt'}

# Remove a variable
$sessionToUse.Variables.Remove('FULLSYNC')
$sessionToUse.Variables.Remove('CUSTOMVARIABLE')

# Query a variable
$sessionToUse.Variables['FULLSYNC']
$sessionToUse.Variables['CUSTOMVARIABLE']

Regarding $PC(ParameterName)$ can I run

Invoke-ImEvent  -EventName "EVENT" -Identity "UID" -Type "TABLE" -EventParameters @{"paramName":"paramValue"} ?

Okay, my bad. If you said variable I somehow replaced this with parameter in my head. But you found the session variables which would be honored during the event generation as well.

Yes, you can use the parameters -Identity and -Type for Invole-ImEvent as well.

But I think your hash-table is wrong. It needs to be @{paramName = "paramValue"}

I will note it down, Thanks Markus!
