• What is the cause and solution for SAP error message CNV10310401 - For DATATYPE=CHAR or NUMC, no entry was found in DD03L for LENG=&!! ?

  The SAP error message CNV10310401 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data transfer tools. This error indicates that there is an issue with the data type definition in the Data Dictionary (DDIC) for a specific field.
  Cause:
  The error message states that for a data type of CHAR or NUMC, no entry was found in the DD03L table for the specified length (LENG=&!!). This usually means that:
  
  Invalid Length: The length specified for the CHAR or NUMC field is not defined in the Data Dictionary. This could happen if the length is set incorrectly in the source data or if the target structure does not match the expected definitions.
  Missing Data Element: The data element associated with the field may not exist or may not be properly defined in the system.
  Custom Development: If the field is part of a custom development or enhancement, it may not have been properly registered in the Data Dictionary.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Dictionary:
  
  Use transaction code SE11 to check the Data Dictionary for the relevant data element or table.
  Look for the specific field and verify that it exists and that the length is correctly defined.
  
  
  
  Verify Source Data:
  
  Ensure that the source data being migrated has the correct lengths for CHAR and NUMC fields. If the source data has lengths that exceed what is defined in the target structure, it will lead to this error.
  
  
  
  Adjust Lengths:
  
  If the lengths are incorrect, adjust them in the source data or modify the target structure to accommodate the required lengths.
  
  
  
  Check Custom Developments:
  
  If the field is part of a custom development, ensure that it has been properly defined in the Data Dictionary and that all necessary entries exist.
