Data synchronization issues in ERP - Construction can disrupt workflows and lead to discrepancies in extracted data. This guide provides a comprehensive troubleshooting workflow, common causes of errors, and validation techniques to help you resolve these issues effectively.
Overview of Data Synchronization Issues
Synchronization problems often arise due to mismatched record counts, errors in entity relationships, or artifacts in reconciliation reports. Addressing these issues requires a systematic approach to identify and resolve discrepancies.
Step-by-Step Troubleshooting Workflow
Follow this end-to-end remediation process to resolve synchronization issues:
Run the Extract Reconciliation Report: - Use this report to identify tables with mismatched record counts. - Run the report outside business hours to avoid interference from other jobs. - For detailed analysis, run the Detailed Reconciliation on specific tables after recompiling datasets.
Check the Extract Monitor: - Ensure the replication agent is running. If it’s red, restart it to prevent record queuing.
Regenerate Entities if Setup Changes Were Made: - Rebuild the SQL table and re-extract data to reflect changes.
Apply the EX Parameter for Parent Entities: - Use the EX parameter to manage parent-child entity relationships. - Follow these steps: - Drop tables for extracts with discrepancies. - Delete the extracts and ensure no residual SQL data remains. - Set the EX parameter for parent entities. - Generate extracts for related entities. - Create tables and extract data. - Run the reconciliation report to confirm matches. - Enable or change CDC as required.
Common Causes and Fixes for Extract Errors
When generating extracts for related entities, errors may occur due to:
Duplicate Item Descriptions: - In the Forecast Model, ensure item descriptions are unique to avoid duplicate column generation. - Modify duplicate descriptions to resolve the issue.
Redundant or Incorrect Entity Relationships: - Check for redundant custom relationships alongside standard ones. - Remove redundant relationships to prevent conflicting column creation. - Regenerate extracts and proceed with table creation and data extraction.
Validating Reconciliation Report Alerts
To determine if an out-of-sync alert is genuine or an artifact of the reconciliation report:
Obtain the actual record count directly from SQL using a SQL tool.
Run the Extract Reconciliation Report manually outside business hours.
Compare the SQL count to the ERP/coins count from the report. - If the counts match but the report shows a discrepancy, the issue may lie with the reconciliation report itself.
Additional Tips for Preventing Sync Issues
Regularly monitor the Extract Monitor to ensure the replication agent is functioning.
Validate entity relationships and metadata to avoid redundant configurations.
Schedule reconciliation reports during low-activity periods to ensure accuracy.
By following these steps and addressing common causes, you can effectively troubleshoot and resolve data synchronization issues in ERP - Construction.
