• What is the cause and solution for SAP error message CNV10994011 - &1: Overlap of structure fields for &2 and &3 ?

  The SAP error message CNV10994011 indicates that there is an overlap of structure fields in the context of data conversion or migration processes, particularly when using the SAP Conversion Tools (like the SAP S/4HANA Migration Cockpit). 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, such as overlapping data types or sizes.
  Data Model Changes: If there have been changes in the data model (for example, during a system upgrade or migration), the new definitions may conflict with existing ones.
  Custom Development: Custom fields or structures that have been added to standard SAP structures may not have been defined correctly, leading to overlaps.
  
  Solution:
  
  Review Structure Definitions: Check the definitions of the structures involved (indicated by &2 and &3 in the error message). Ensure that the fields do not overlap in terms of their data types and sizes.
  Adjust Field Lengths: If the fields are overlapping, consider adjusting the lengths or types of the fields to ensure they fit within their allocated space without conflict.
  Check Custom Code: If custom developments are involved, review the code to ensure that the fields are defined correctly and do not overlap with standard fields.
  Use SAP Tools: Utilize SAP tools like the Data Migration Cockpit or the SAP S/4HANA Migration Object Modeler to help identify and resolve issues related to data structure overlaps.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion process you are undertaking for additional guidance.
