• What is the cause and solution for SAP error message CNV_10030018 - &1 cardinality requirements were loaded ?

  The SAP error message CNV_10030018 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 there are cardinality requirements that were loaded, which may not align with the expected data model or configuration.
  Cause:
  
  
  Cardinality Mismatch: The error often arises when the cardinality (the relationship between entities, such as one-to-one, one-to-many, etc.) defined in the data model does not match the actual data being loaded. This can happen if the source data does not conform to the expected structure or if there are inconsistencies in the data relationships.
  
  
  Configuration Issues: There may be configuration settings in the migration tool or the target system that do not align with the source data.
  
  
  Data Quality Issues: The source data may contain duplicates, missing values, or other anomalies that violate the cardinality constraints.
  
  
  Solution:
  
  
  Review Data Model: Check the data model definitions in the target system to ensure that they match the source data structure. Pay special attention to the cardinality settings.
  
  
  Data Cleansing: Before migration, perform data cleansing on the source data to eliminate duplicates, fill in missing values, and ensure that the data adheres to the expected relationships.
  
  
  Adjust Migration Settings: If necessary, adjust the migration settings in the SAP tool to accommodate the specific characteristics of your source data.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be guidelines or best practices for handling cardinality issues.
  
  
  Testing: Conduct thorough testing with a subset of data to identify and resolve any issues before performing a full migration.
