The SAP error message CNV20551697, which states "Adjustment not possible because prior steps are already executed," typically occurs during data migration or conversion processes, particularly when using SAP's tools for data migration, such as the SAP S/4HANA Migration Cockpit or other conversion tools.
Cause: This error indicates that the system has detected that certain prerequisite steps in the migration or conversion process have already been executed. This can happen for several reasons: Incomplete Process Flow: The migration process is designed to be executed in a specific sequence. If a step that should have been executed prior to the adjustment step has already been completed, the system will not allow further adjustments.
