• What is the cause and solution for SAP error message /SAPDMC/LSMW_OBJ_020009 - Target structure is the same as the structure to be appended. ?

  The SAP error message /SAPDMC/LSMW_OBJ_020009 indicates that there is an issue with the structure you are trying to append in the Legacy System Migration Workbench (LSMW). Specifically, the error message states that the target structure is the same as the structure you are trying to append, which is not allowed.
  Cause:
  This error typically occurs when:
  
  You are trying to append a structure to itself, which is logically incorrect.
  There may be a misconfiguration in the LSMW project where the source and target structures are not properly defined.
  The mapping of fields in the LSMW project may be incorrectly set up, leading to a situation where the system interprets the target structure as the same as the source structure.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the Target Structure: Ensure that the target structure you are trying to append to is different from the source structure. Review the definitions of both structures in your LSMW project.
  
  
  Review Field Mapping: Go through the field mapping in your LSMW project. Make sure that the fields from the source structure are being mapped correctly to the target structure. If you are trying to append fields, ensure that they are not being mapped to the same structure.
  
  
  Modify the LSMW Project:
  
  If you have mistakenly set the same structure for both source and target, correct this in the LSMW project settings.
  If you need to create a new structure, ensure that it is defined correctly and is distinct from the existing structures.
  
  
  
  Test the Changes: After making the necessary adjustments, test the LSMW project again to see if the error persists.
  
  
  Consult Documentation: If you are unsure about the structures or the mapping, refer to the SAP documentation or help resources related to LSMW for guidance on how to properly set up your project.
