Hi Alexandre,

Here's an automation script that should more or less do the job for you, hope this helps

using Skyline.DataMiner.Automation;
using System;
using Skyline.DataMiner.Net;
using Skyline.DataMiner.Net.Masking;
using Skyline.DataMiner.Net.Messages;
using Skyline.DataMiner.Net.CPE;

internal class Script
{
private Engine _engine;
private const string SCRIPT_NAME = "Mask EPM";
private String _systemType;
private String _systemName;
private bool _mask = true;

public void Run(Engine engine)
{
_engine = engine;

try
{
_systemType = _engine.GetScriptParam("System Type").Value;
_systemName = _engine.GetScriptParam("System Name").Value;

if (!bool.TryParse(_engine.GetScriptParam("Mask").Value, out _mask)
){
_engine.GenerateInformation($"'{SCRIPT_NAME}' - Could not parse mask bool from Parameters");
}

Masking.InitMasking(engine);
Masking.SetMaskedStateForEPM(engine.UserDisplayName, _mask,_systemType, _systemName);
}
catch (Exception e)
{
_engine.GenerateInformation($"'{SCRIPT_NAME}' - " + e.ToString());
}
}

}

public static class Masking
{
private static CPECollectorHelper _helper;

public static void InitMasking(Engine engine){
_helper= new CPECollectorHelper(Engine.SLNetRaw);
}

public static void SetMaskedStateForEPM(String user, bool mask, String systemType, String systemName)
{
_helper.MaskLinkedDMAObjectRefTreesThroughTopology(
new MaskInfo()
{
DoMask = mask,
MaskType = MaskType.UntilUnmask,
Reason = "masking test"
},
systemType,
systemName
);
}
}
