  The SAP error message DMC_GENERAL355 indicates that there is an attempt to drop a staging table, but the operation fails because the table is not empty. This error typically occurs in the context of data management and data migration processes, particularly when using SAP Data Management or SAP Data Intelligence.
  Cause:

  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the Contents of the Staging Table:
  
  Before attempting to drop the table, check if it contains any data. You can do this by executing a simple SQL query to count the records in the table:
  SELECT COUNT(*) FROM <staging_table_name>;
  
  
  
  
  Delete the Data:
  
  If the table contains data and you are sure that you want to drop it, you need to delete the data first. You can do this with a DELETE statement:
  DELETE FROM <staging_table_name>;
  
  Alternatively, if you want to remove the table and its data in one go, you can use the TRUNCATE command (if supported), which is more efficient for large tables:
  TRUNCATE TABLE <staging_table_name>;
  
  
  
  
  Drop the Staging Table:
  
  After ensuring that the table is empty, you can proceed to drop the table:
  DROP TABLE <staging_table_name>;
  
  
  
  
  Related Information:
