Access variables in a workflow

[martin_kohler]

Hello,

I created a new Catalog Item Request workflow including a custom workflow activity that runs a PowerShell script. For this activity I created two input variables that are used in the script. I am now struggeling with how to access those variables from the workflow. The variables are:

• a custom attribute on the catalog item ("Software ID" in Screenshot below)
• a (global) catalog variable with reference to the cmdb_ci_computer table ("Computer" in screenshot below)

Can anyone help me what I need to enter there? In other threads I found "current.variables.<variablename>" which did not work out.

Thanks in advance for your help,

Martin

Hi Martin,

Any idea where that PowerShell script came from? I'm no PS expert, but it would seem that the quotes are interpreting it as a literal string instead of the value of your variable. It makes me wonder if it shouldn't be something more like:

Where{ $_.name -eq \"current.variables.target_computer\" }

Just a hunch based on other languages and parsers.

Hi Chuck,

thanks for your hint. The PowerShell script works fine when I manually enter a computer name in the workflow definition:

results in

in the script and it works fine. So it actually expects a string there.

The workflow activity contains input variables

that are then used in the execution command:

The error seems to be somewhere between the workflow definition where I need to specify the values for the activity input variables and the actual running activity. What I enter in the workflow definition is not "translated" to the values but taken 1:1.

Any ideas on that? I might do something very basic wrong, I am not that familiar with the ServiceNow workflows.

Thanks and kind regards,

Martin
