Read a run step by step

Open a run and read it one step at a time: what each step received, what it produced, and where the run stopped if something failed.

By the end of this page, you will be able to open any run and see, step by step, what Loopfour received, what it did, and what it produced. This is the support you show a reviewer for a single item, such as one invoice or one bill.

Before you start

You need access to Studio. Any member of your company can open runs.

Open and read a run

Open the run

Select Runs in the sidebar and select the run's name. You can also open it from a link someone shared with you.

Read the header

The top of the page shows the workflow name, a one-line summary of what happened and the run's status. Under it you see the run ID, how the run started (for example Schedule or Manual), when it started, how long it ran and the Workflow version it used.

If the run is a retry of an earlier run, or was retried later, the header links to the other run.

Follow the steps

Under What happened, the workflow is drawn as its steps. Switch between Flow, which shows the shape of the workflow, and Timeline, which shows the steps in the order they ran. Each step is marked, for example Done, Failed, Not run or Waiting for approval.

Open a step

Select a step to open its details on the right.

Overview says what the step did and how long it took.
Input shows what the step received, such as the invoice fields it was given.
Output shows what it produced, such as the record it created. For a failed step, this tab is called Error and shows the error.

Values of your saved secrets are hidden in the recorded data.

Replay the run if it helps

Use the replay bar to step through the run from the start. Previous block and Next block move one step at a time. Skip waits jumps over long pauses, such as a wait for approval.

What some steps show

A decision shows its Answer, Yes or No. Steps on the path not taken are marked as not run, so you can see why they were skipped.
An approval shows Approved, Rejected or Timed out, and lists Asked by (Email or Slack), Decided by and how long it Waited. While it is still waiting, it shows Approvers, Asked, Due and the facts the workflow gathered.
A failed step shows What went wrong, then either You can fix this with the steps To fix it, or Loopfour support needs to fix this. Already done in this run lists work the run finished before it failed, so you know what not to repeat by hand. When the explanation was written by AI, it says Explained by Loopfour AI.

Select the More run actions menu at the top right, then Copy link to this run or Copy run ID. Send the link to a colleague, or include it when you contact support.

Check it worked

You can identify which steps finished, which failed or were not run, and what the selected step received and produced. Compare any ledger changes with the corresponding records in that system.

If something goes wrong

"This run was not found": the run may have been deleted, or the link may be wrong. Runs are only visible inside the company they belong to, so check you are signed in to the right one.
"You are signed out": select Sign in and open the link again.
The run failed: see Fix and retry a failed run.
A message you do not understand: see Error messages explained.
