expense failed: attendee list required error

Export

Fixes attendee-list validation failures by adding the attendees to the meals or entertainment expense. Use when an expense is blocked because the attendee list is missing. Not for business-purpose-only flags.

TL;DR

Meals and entertainment expenses require an attendee list for audit, and the expense was submitted without one. Add every attendee (name and company), save, and resubmit; the validation passes once the list is present.

Error

expense failed: attendee list required

Steps

  1. Open the flagged meals or entertainment expense. Expected: the attendee field is empty.
  2. List all attendees: names and their companies, including yourself. Expected: a complete list.
  3. Enter the attendees in the expense's attendee field. Expected: the field shows every attendee.
  4. Check the business purpose is also filled in, since the two often go together. Expected: both fields complete.
  5. Resubmit. Expected: the attendee validation passes.

When to use

  • An expense fails validation requiring an attendee list.
  • The expense is meals, entertainment, or client hospitality.

When not to use

  • Only a business purpose is missing (see the business-purpose skill).
  • The attendee list exists but the approver questions it (clarify in comments).

Tool compatibility

  • SAP Concur, Expensify, and policy-audited expense tools.

Why it happens

Tax and policy rules require knowing who benefited from meals and entertainment. The attendee list is the audit evidence, so validation blocks the expense until it is provided.
