  The SAP error message CNV_10030020 typically relates to issues encountered during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. The message indicates that additional cardinality requirements have been created, which means that the system has identified a need for more specific relationships between data entities than what was originally defined.
  Cause:
  
  Data Model Changes: The underlying data model may have changed, leading to new relationships or cardinality requirements that were not accounted for in the initial setup.
  Inconsistent Data: The data being migrated may have inconsistencies or violations of expected relationships, prompting the system to create additional cardinality requirements to ensure data integrity.

  Solution:
  
  Review Data Model: Check the data model and relationships defined in the source and target systems. Ensure that they align with the expected cardinality.
  Data Cleansing: Perform data cleansing on the source data to resolve any inconsistencies or violations of cardinality. This may involve removing duplicates, correcting relationships, or ensuring that mandatory fields are populated.
  Adjust Migration Settings: Review and adjust the settings in the migration tool to ensure they are correctly configured to handle the data being migrated.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration tool you are using. There may be specific guidelines or best practices for handling cardinality issues.
