Invoke workflow file is a good process if we have a complex automation project. We can divide it into smaller parts and then, by using the Invoke workflow file activity, we can collect all these smaller parts in a single workflow file. However, if we want to invoke previously created workflows in our new workflow and make changes to the new workflow, the previous workflow will also get affected. Hence, it is recommended to use the Invoke workflow file activity only when we have a complex workflow and we want to divide the process into smaller parts and then use them together. There is another property for that, what we need here; it's as follows:

As shown in the preceding screenshot, the Invoke workflow activity requires a variable expression. We can create a variable and set a timeout that is required for the Invoke workflow file activity.
