Salesforce DevOps Center helps teams manage merge conflicts that occur when multiple developers modify the same metadata components across different environments. Conflicts are detected during promotion between pipeline stages when source control systems cannot automatically reconcile changes to shared components. The system provides detection, prevention through work item combination, and resolution tools to keep releases moving forward.

Core information
  • Merge conflicts occur when multiple work items contain the same metadata components, especially when multiple developers make changes to the same components in different development environments
More details and nuances
  • Combining work items cannot be undone; work items move only forward through the pipeline and cannot be reverted to Never status after promotion to the first stage
