A **Financial Event Line** is a single ledger entry tied to a parent Financial Event, which comes from an order or a payment. Fetching is the first step in closing a period. When you click **Fetch**, fusionCore finds every succeeded Financial Event Line whose event date falls inside the period's **Start Date** and **End Date**, then links each line to the period. After a fetch, you can review the gathered lines and move on to [locking the period](/end-user-guides/accounting/financial-periods/locking-financial-periods). fusionCore organizes the supporting financial data for an accounting timeframe; it does not post journal entries or debits and credits. Your general ledger system creates journal entries by importing the data fusionCore provides. ## Before You Start * The period's **Status** must be **Open**. Fetch is unavailable on a **Closed** period. * No other fetch or lock job can be running on the same period at the same time. ## How to Fetch Financial Event Lines From the list view, click the name of the **Financial Period** you want to fetch. Financial Period list view with a period name to open At the top right-hand side of the record, click **Fetch**. Fetch button at the top right of a Financial Period record The fetch runs as a background job. When it finishes, a pop-up appears with a success message. Success pop-up after a fetch completes Refresh the page. The gathered **Financial Event Lines** now appear linked to the period. Financial Event Lines linked to the Financial Period after refresh ## How to Confirm the Result You can check progress without watching the pop-up: * **Batch Job Status** moves through `Processing Fetch` and lands on `Completed Fetch` when the job succeeds, or `Fetch Error` if it fails. * If the job fails, the **Batch Job Error Message** section on the record shows the detail. ## Limitations and Common Pitfalls * **Fetch only picks up succeeded, in-range lines.** A line is linked only when its parent Financial Event has a status of `Succeeded` and a succeeded date inside the period's date range. Non-succeeded or out-of-range lines are skipped silently. If a line should have been linked but was not, locking the period will later fail. * **Fetch needs an Open period.** If the period is **Closed**, the **Fetch** button reports that the action is available only for Open Financial Periods. A closed period cannot be re-fetched from this button. * **One job at a time.** You cannot start a second fetch or a lock while a job is still running. Wait for **Batch Job Status** to leave the `Processing` state. * **Fetch links, it does not lock.** Fetching only associates lines with the period. The lines stay editable until you [lock the period](/end-user-guides/accounting/financial-periods/locking-financial-periods).
