  The SAP error message CNV_10996030 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 there is an issue with the derivation logic in the field reference mapping, specifically in the context of the conversion of data from one format or structure to another.
  Cause:
  The error message CNV_10996030 suggests that there are errors in the derivation rules defined for the fields involved in the conversion process. This could be due to several reasons, including:
  
  Incorrect Mapping: The source and target fields may not be correctly mapped, leading to inconsistencies.
  Data Type Mismatch: The data types of the source and target fields may not be compatible.
  Missing Values: Required fields may be missing values, which are necessary for the derivation logic to work.
  Invalid Logic: The derivation logic itself may contain errors, such as syntax errors or logical inconsistencies.
  Configuration Issues: There may be issues in the configuration of the migration project or the specific transformation rules.
  
  Solution:
  To resolve the error CNV_10996030, you can follow these steps:
