The SAP error message CNV20551679 indicates that there is an issue with the investment program position in the system. Specifically, it suggests that the investment program position you are trying to reference (denoted as &2) is superior to another position (denoted as &4) that is not defined in the system. This typically occurs during data migration or when trying to establish relationships between investment program positions.
Cause: Missing Investment Program Position: The superior investment program position (&4) is not defined in the system, which means that the hierarchy is broken.
