Using Variables Pane
When working inside the Workflow Builder, the Variables pane on the right gives you a one-stop place to keep track of all the variables that are used or can be used by the workflow, including non-workflow variables like global variables and module variables.
The Variables pane also gives you quick clipboard access to variable names. To copy a variable name to the clipboard, click the variable name in the pane.
To collapse the pane, click the arrow icon on the Reference toolbar.
Assume that you want to build a URL on the fly and include in it a piece of data that you extract from Active Directory (AD).
You would start by using one of the AD activities to get the data. Let's say you named it getUserFolder.
To construct the URL, you will need the Memory Set activity. In it, first provide a name for the variable that you are creating in Variable Name—userVaultPath for example. In Variable Value, construct the URL, referencing the %getUserFolder% activity result:
http://www.example.com/vault?userpath=%getUserFolder%
After you construct the URL, you can refer to it from other activities using the user-defined variable name (%userVaultPath% in this case). Note that, unlike other activities, you don't use the Memory Set activity's instance name to refer to its result.
