Occasionally you may encounter synchronization errors when posting an invoice in Centime. Synchronization errors are your ERP's way of rejecting information that does not comply with its settings in order to keep data clean and correct within your system of record. ### Mandatory fields If your ERP has mandatory fields to code (e.g. location, department, class) and if you don't code them in Centime, the invoice will not post to the ERP. Your ERP will reject any invoice Centime tries to post if it does not contain the fields that your ERP requires. This appears in Centime as a synchronization error message that needs to be resolved.    To resolve, simply fill in all fields that are mandatory in your ERP and repost in Centime.    #### Account period is closed or locked This can occur when the invoice date on your document is for an accounting period that is already closed or locked within your ERP. To resolve this, you can do one of the following: - Open the closed or locked period in your ERP and repost from Centime - Change the invoice date in Centime to an open period in your ERP and repost - Delete the invoice in Centime and restart the process   The option you choose should be based on your organization's accounting best practices. - [Getting started with Centime](https://knowledgebase.centime.com/support/getting-started-with-centime?hsLang=en-us#main-content) - [Post-integration Setup](https://knowledgebase.centime.com/support/getting-started-with-centime?hsLang=en-us#post-integration-setup) - [Centime basics](https://knowledgebase.centime.com/support/getting-started-with-centime?hsLang=en-us#centime-basics) - [Manage Payables](https://knowledgebase.centime.com/support/manage-payables?hsLang=en-us#main-content) - [Introduction and Configuration](https://knowledgebase.centime.com/support/manage-payables?hsLang=en-us#introduction-and-configuration) - [Invoice Automation](https://knowledgebase.centime.com/support/manage-payables?hsLang=en-us#invoice-automation) - [Document Splitter](https://knowledgebase.centime.com/support/manage-payables?hsLang=en-us#document-splitter) - [Advanced NetSuite workflow support](https://knowledgebase.centime.com/support/manage-payables?hsLang=en-us#advanced-netsuite-workflow-support) - [Payment Automation](https://knowledgebase.centime.com/support/manage-payables?hsLang=en-us#payment-automation) - [Payment Methods](https://knowledgebase.centime.com/support/manage-payables?hsLang=en-us#payment-methods) - [Manage Receivables](https://knowledgebase.centime.com/support/manage-receivables?hsLang=en-us#main-content) - [Create your Receivables Strategy](https://knowledgebase.centime.com/support/manage-receivables?hsLang=en-us#create-your-receivables-strategy) - [Introduction to the Receivables Module](https://knowledgebase.centime.com/support/manage-receivables?hsLang=en-us#introduction-to-the-receivables-module) - [Collections & Collaboration](https://knowledgebase.centime.com/support/manage-receivables?hsLang=en-us#collections-collaboration) - [CentimePay](https://knowledgebase.centime.com/support/manage-receivables?hsLang=en-us#centimepay) - [Merchant Services](https://knowledgebase.centime.com/support/manage-receivables?hsLang=en-us#merchant-services) - [Cash Application](https://knowledgebase.centime.com/support/manage-receivables?hsLang=en-us#cash-application) - [Cash Flow Workbench](https://knowledgebase.centime.com/support/cash-flow-workbench?hsLang=en-us#main-content) - [Overview](https://knowledgebase.centime.com/support/cash-flow-workbench?hsLang=en-us#overview) - [Using Cash Flow Workbench](https://knowledgebase.centime.com/support/cash-flow-workbench?hsLang=en-us#using-cash-flow-workbench) - [Cash Flow Settings](https://knowledgebase.centime.com/support/cash-flow-workbench?hsLang=en-us#cash-flow-settings) - [Monitor KPIs](https://knowledgebase.centime.com/support/monitor-kpis?hsLang=en-us#main-content) - [Overview](https://knowledgebase.centime.com/support/monitor-kpis?hsLang=en-us#overview) - [CentimeCredit](https://knowledgebase.centime.com/support/centimecredit?hsLang=en-us#main-content) - [Getting Started](https://knowledgebase.centime.com/support/centimecredit?hsLang=en-us#getting-started) - [Banking](https://knowledgebase.centime.com/support/banking?hsLang=en-us#main-content) - [Manage Banking](https://knowledgebase.centime.com/support/banking?hsLang=en-us#manage-banking) - [Product Release Notes](https://knowledgebase.centime.com/support/product-release-notes?hsLang=en-us#main-content) - [2026 Releases](https://knowledgebase.centime.com/support/product-release-notes?hsLang=en-us#2026-releases) - [2025 Release](https://knowledgebase.centime.com/support/product-release-notes?hsLang=en-us#2025-release) - [2024 Releases](https://knowledgebase.centime.com/support/product-release-notes?hsLang=en-us#2024-releases) - [2023 Releases](https://knowledgebase.centime.com/support/product-release-notes?hsLang=en-us#2023-releases) - [2022 Releases](https://knowledgebase.centime.com/support/product-release-notes?hsLang=en-us#2022-releases) - [Customer Portal](https://knowledgebase.centime.com/support/customer-portal?hsLang=en-us#main-content) - [Using the Customer Portal](https://knowledgebase.centime.com/support/customer-portal?hsLang=en-us#using-the-customer-portal) [![Centim App Logo](https://knowledgebase.centime.com/hubfs/Centim%20App%20Logo.svg "Centim App Logo")](https://knowledgebase.centime.com/support?hsLang=en-us) 123 Waverly Pl., Boston, MA 02135 Copyright © 2024, Centime, Inc.
