  Cause:
  
  Data Migration Context: The error usually occurs when the system is trying to map data from one structure to another, and it finds that the mapping for the specified object (J_OBJNR) is not necessary or not defined.
  Configuration Issues: There may be a configuration issue in the data migration settings or the mapping rules that are supposed to be applied to the ONRAO table.
  Missing Data: The data that is expected to be present in the ONRAO table may be missing or not correctly populated, leading to the system not finding a need for mapping.
  
  Solution:
  
  Check Mapping Configuration: Review the mapping configuration for the data migration process. Ensure that the mapping for J_OBJNR is correctly defined if it is indeed required.
  Review ONRAO Table: Check the ONRAO table to ensure that it contains the necessary data and that the structure is as expected. If the table is empty or incorrectly populated, you may need to address that first.
  Consult Documentation: Refer to the SAP documentation related to the specific migration or conversion process you are executing. There may be specific instructions or prerequisites that need to be followed.
  Adjust Migration Settings: If the mapping for J_OBJNR is not needed, you may need to adjust the migration settings to bypass this mapping or to ensure that the process continues without it.
