Smart SAP Assistant

• What is the cause and solution for SAP error message DT163 - Table & is a History table; conversion is not possible. ?

  The SAP error message DT163 indicates that the table you are trying to convert is a history table, and therefore, the conversion is not possible. This typically occurs when you are attempting to perform a data dictionary operation (like changing the structure of a table) on a table that is designated to store historical data.
  Cause:
  
  History Table: The table in question is defined as a history table, which means it is intended to store historical records and is not meant to be modified in the same way as regular tables.
  Data Dictionary Operations: You might be trying to perform an operation that is not allowed on history tables, such as changing the table structure or converting it to a different type.
  
  Solution:
  
  Review Table Definition: Check the definition of the table in the Data Dictionary (SE11) to confirm that it is indeed a history table. You can do this by looking at the table attributes.
  Avoid Modifications: If the table is a history table, avoid trying to modify its structure. Instead, consider whether you need to create a new table or use a different approach to achieve your goal.
  Use Appropriate Transactions: If you need to work with historical data, use appropriate transactions or reports designed for that purpose, rather than trying to convert or modify the history table.
  Consult Documentation: Refer to SAP documentation or consult with your SAP Basis or ABAP team for guidance on how to handle history tables appropriately.
