  The SAP error message CNV071 indicates that during a data conversion or migration process, certain entries of type 'WARNING' were dropped. This typically occurs in the context of data migration projects, especially when using tools like SAP's Data Migration Workbench or other conversion tools.
  Cause:
  
  Data Quality Issues: The warnings may arise from data that does not meet the required standards or formats expected by the target system. This could include invalid data types, missing mandatory fields, or data that violates business rules.
  Configuration Issues: The configuration settings for the migration process may not be correctly set up, leading to warnings being generated for certain entries.
  Mapping Errors: If the mapping between source and target fields is incorrect or incomplete, it can lead to warnings that result in dropped entries.
  Thresholds: There may be thresholds set in the migration tool that dictate how many warnings can be tolerated before entries are dropped.
  
  Solution:
  
  Review Warnings: Check the detailed log or output of the migration process to identify the specific warnings that were generated. This will help you understand why the entries were dropped.
  Data Cleansing: Cleanse the data in the source system to resolve any issues that are causing warnings. This may involve correcting data formats, filling in missing values, or ensuring compliance with business rules.
  Adjust Configuration: Review and adjust the configuration settings of the migration tool to ensure they align with the requirements of the target system.
  Mapping Verification: Verify the mapping of fields between the source and target systems to ensure that all necessary fields are correctly mapped and that there are no discrepancies.
  Increase Warning Threshold: If appropriate, consider increasing the threshold for warnings in the migration tool to allow for more entries to be processed, but be cautious as this may lead to data quality issues.
  Testing: Conduct thorough testing of the migration process with a smaller dataset to identify and resolve issues before performing a full migration.
