A method and associated system for an automatically self-learning audit of a bidirectional synchronization means for synchronizing a source system and a target system. A processor identifies a mismatch between an element of production data of the source system and an analogous production-data element of the target system. If the mismatch is caused by an issue known to the synchronization means, the processor takes corrective action known to resolve the mismatch. Otherwise, the processor attempts to identify a resolution and, if successful, applies the resolution, teaches the resolution to the synchronization mechanism, records the solution, and resends data from the correct system to the incorrect system. If unable to identify a resolution, the processor implements a next-best solution that allows continued operation despite the unresolved mismatch. The processor then generates a report of the mismatch and continues searching for other mismatches in the loaded data models.
