• What is the cause and solution for SAP error message TA199 - Identical tables ?

  The SAP error message TA199, which states "Identical tables," typically occurs when there is an attempt to create or modify a table in the Data Dictionary (SE11) that has the same structure and attributes as an existing table. This can happen during the creation of a new table or when trying to define a new view that is identical to an existing one.
  Cause:
  
  Duplicate Table Definition: The most common cause is that the table you are trying to create already exists in the system with the same name and structure.
  Copying Tables: If you are trying to copy an existing table or view and inadvertently create a new one with the same attributes, this error can occur.
  Transport Issues: Sometimes, transport requests can lead to conflicts if the same table is being transported multiple times.
  
  Solution:
  
  Check Existing Tables: Before creating a new table, check the Data Dictionary (SE11) to see if a table with the same name or structure already exists. If it does, consider using the existing table instead of creating a new one.
  Rename the New Table: If you need to create a new table with a similar structure, consider renaming it to avoid conflicts.
  Modify Existing Table: If your intention is to modify an existing table, you can do so directly rather than creating a new one.
  Use Views: If you need to represent data from multiple tables, consider creating a view instead of a new table.
  Transport Management: If the issue arises from transport requests, ensure that the transport requests are correctly managed and that there are no duplicate entries being transported.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like SE11 (Data Dictionary), SE14 (Database Utility), and SE80 (Object Navigator) to manage tables and views.
