答案（中文）
如果您的 IUCLID 档案中的物质标识符与 REACH-IT 联合提交页面上的物质标识符不匹配，则会导致业务规则 027 (BR027) 失败。为避免将来提交时出现 BR027 失败，请参阅以下检查清单并执行适用于您案例的步骤。提交 IUCLID 档案时，请确保您在 REACH-IT 中选择了正确的联合提交方式。请确保您的 IUCLID 档案中的 EC 编号与 REACH-IT 中联合提交的 EC 编号相同。您可以从 REACH-IT 联合提交页面、Pre-SIEF 页面或查询提交报告页面导出分配的 EC 编号。将 EC 编号导入 IUCLID 并将其分配给您的参考物质，如问答 1258 中所述。如果您的物质尚无 EC 编号，请检查 REACH-IT 联合提交页面上的物质名称拼写是否与您的 IUCLID 档案第 1.1 节 IUPAC 名称中的拼写相同。请注意额外的空格和特殊字符。如果您的物质是多成分物质（例如反应物料……），请确保 IUCLID 第 1.2 节中指示的所有成分与 REACH-IT 联合提交页面中包含的成分相同。如果您是新联合提交的物质（成分未知或可变、反应产物复杂或生物来源 (UVCB)）的牵头注册人，且没有有效的预注册或查询编号，并且已尝试上述修复方法，请使用 ECHA 联系表联系 ECHA，以获取有关如何成功提交注册的进一步说明。在创建您的档案时，ECHA 建议您使用 IUCLID 验证助手插件来帮助您检测数据集和档案中的任何业务规则和技术完整性检查失败，如问答 0392 中所述。请解决任何检测到的失败，然后再通过 REACH-IT 向 ECHA 重新提交您的档案更新。
Answer (EN)
Business rule 027 (BR027) failure occurs if the substance identifier in your IUCLID dossier does not match the substance identifier on the REACH-IT joint submission page. To avoid BR027 failure in your future submissions, see the following check list and carry out the steps that apply to your case.Check that you have selected the correct joint submission in REACH-IT when submitting your IUCLID dossier.Check that the EC number in your IUCLID dossier is the same as the EC number of the joint submission in REACH-IT. You can export the assigned EC number either from the REACH-IT joint submission page, from the Pre-SIEF page, or from the inquiry submission report page. Import the EC number into IUCLID and assign it to your reference substance, as specified in Q&A 1258.If no EC number exists for your substance yet, check that the spelling of your substance name on the REACH-IT joint submission page is identical to the spelling in your IUCLID dossier section 1.1 IUPAC name. Pay attention to additional spaces and special characters.If your substance is a multi-constituent substance (e.g. a reaction mass of…), make sure that all the constituents indicated in section 1.2 of IUCLID are identical to the constituents included in the REACH-IT joint submission page.If you are a lead registrant of a new joint submission for a substance of Unknown or Variable composition, Complex reaction products or Biological origin (UVCB) with no valid pre-registration or inquiry number, and have tried the above mentioned fixes, please contact ECHA using the ECHA contact form to receive further instructions on how to successfully submit a registration.While creating your dossier, ECHA advises you to use the IUCLID Validation assistant plug-in to help you to detect any business rules and technical completeness check failures in your dataset and dossier, as explained in Q&A 0392. Please address any detected failures before re-submitting your dossier update to ECHA through REACH-IT.
