• What is the cause and solution for SAP error message COM_DML_CUST001 - Database table & already exists ?

  The SAP error message COM_DML_CUST001 indicates that there is an attempt to create a database table that already exists in the system. This error typically occurs during data migration, system upgrades, or when executing custom programs that involve database operations.
  Cause:
  
  Table Already Exists: The most straightforward cause is that the database table you are trying to create is already present in the database.
  Duplicate Execution: The operation that creates the table may have been executed multiple times, leading to the error.
  Incorrect Logic in Custom Code: If you are running custom ABAP code or a program that includes logic to create tables, there may be a flaw in the logic that does not check for the existence of the table before attempting to create it.
  
  Solution:
  
  Check for Existing Table: Before attempting to create the table, check if it already exists. You can do this by querying the database or using transaction codes like SE11 (Data Dictionary) to see if the table is listed.
  Modify the Code: If you are using custom ABAP code, modify it to include a check for the existence of the table before attempting to create it. You can use the following SQL statement:
  SELECT SINGLE * FROM <table_name> INTO @DATA(result).
  IF sy-subrc <> 0.
      " Table does not exist, proceed to create it
  ELSE.
      " Table already exists, handle accordingly
  ENDIF.
  
  Drop the Table (if appropriate): If the table is not needed and you want to recreate it, you can drop the existing table using the appropriate SQL command. Be cautious with this approach, as it will delete all data in the table.
  DROP TABLE <table_name>;
  
  Review Migration/Upgrade Procedures: If this error occurs during a migration or upgrade, review the procedures to ensure that they are not attempting to create tables that already exist.
  
  Related Information:
  
  Transaction Codes: Use SE11 to view the Data Dictionary and check for existing tables. SE14 can be used for database utility operations.
