• What is the cause and solution for SAP error message /SAPDMC/LSMW_OBJ_020026 - A table/structure with the name '&' already exists in the repository ?

  The SAP error message /SAPDMC/LSMW_OBJ_020026 indicates that there is an attempt to create a table or structure in the SAP Data Migration Cockpit (DMC) or Legacy System Migration Workbench (LSMW) that already exists in the repository. This can occur during data migration processes when the system detects a naming conflict.
  Cause:
  
  
  Duplicate Naming: The most common cause is that a table or structure with the same name already exists in the repository. This can happen if:
  
  The same migration object is being created multiple times.
  There was a previous migration attempt that created the object, and the current attempt is trying to create it again.
  There is a naming conflict due to similar naming conventions used in different migration projects.
  
  
  
  Repository Issues: Sometimes, there may be issues with the repository itself, such as inconsistencies or corruption.
  
  
  Solution:
  
  
  Check Existing Objects: 
  
  Go to the Data Migration Cockpit or LSMW and check if the object with the name indicated in the error message already exists.
  If it does exist and is not needed, you can delete or rename it.
  
  
  
  Rename the Object: 
  
  If you need to create a new object, consider renaming the new table or structure to avoid the conflict.
  
  
  
  Review Migration Projects: 
  
  Ensure that you are not inadvertently trying to create the same object in multiple migration projects. Review your project structure and naming conventions.
  
  
  
  Clear Repository Cache: 
  
  In some cases, clearing the cache or refreshing the repository may help resolve inconsistencies.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or notes related to the specific version of the Data Migration Cockpit or LSMW you are using for any known issues or additional troubleshooting steps.
