CNV_10020341 - Details

• The SAP error message CNV_10020341, which states "Maximum cardinality for &3 &4 has not been maintained," typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that the maximum cardinality (the maximum number of instances of a relationship) for a specific entity or object has not been properly defined or maintained in the system.

  Migration Settings: During the migration process, if the source data does not conform to the expected structure or cardinality defined in the target system, this error can occur.
  Custom Development: If there are custom developments or modifications in the data model that do not adhere to the standard cardinality
