• What is the cause and solution for SAP error message CNV20551557 - &1: Overlap of structure fields for &2 and &3! ?

  The SAP error message CNV20551557 indicates that there is an overlap of structure fields in the context of data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error typically arises when two or more fields in a structure are defined in such a way that their memory allocation overlaps, which can lead to data integrity issues.
  Cause:
  
  Field Overlap: The error occurs when two fields in a structure are defined in a way that they occupy the same memory space. This can happen due to incorrect field definitions or misalignment in the data structure.
  Data Mapping Issues: During data migration, if the mapping of fields from the source to the target structure is not done correctly, it can lead to overlaps.
  Changes in Data Structures: If there have been changes in the data structures (e.g., adding or removing fields) without proper adjustments in the migration logic, it can cause overlaps.
  
  Solution:
  
  Review Field Definitions: Check the definitions of the fields in the structures mentioned in the error message (&2 and &3). Ensure that there are no overlapping definitions.
  Adjust Data Mapping: If you are using a migration tool, review the mapping of fields from the source to the target. Ensure that each field is mapped correctly and does not overlap with others.
  Modify Structures: If necessary, modify the structures to eliminate overlaps. This may involve changing the order of fields, adjusting their lengths, or renaming them.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion process you are using. There may be specific guidelines or best practices to follow.
  Testing: After making changes, perform thorough testing to ensure that the migration process works without errors and that data integrity is maintained.
