  The SAP error message SOI696 indicates that there is an issue with a Data Dictionary Conversion Exit (DDCNVEXIT) entry in the specified table. This error typically arises when the conversion exit is defined for a field in a table, but the associated class does not implement the required method or interface.
  Cause:
  
  Missing Implementation: The class specified in the error message (&2) does not implement the method or interface that is expected (&3). This can happen if the class was not properly defined or if there was a change in the system that affected the implementation.
  Configuration Issues: There may be configuration issues in the Data Dictionary or the conversion exit settings that lead to this inconsistency.
  Transport Issues: If the system has recently undergone a transport of changes, it is possible that the transport did not include all necessary components, leading to missing implementations.
  
  Solution:
  
  Check Class Implementation: Verify that the class specified in the error message (&2) exists in the system and that it implements the required method or interface (&3). You can do this by navigating to the class in the ABAP Workbench (SE80) and checking its methods.
