• What is the cause and solution for SAP error message GT817 - Table & cannot be copied (incorrect type) ?

  The SAP error message GT817 indicates that there is an issue with copying a table due to an incorrect type. This error typically arises when there is a mismatch in the data types or structures of the source and target tables during a copy operation, such as when using the Data Dictionary (SE11) or during transport requests.
  Cause:
  
  Data Type Mismatch: The source table and the target table may have different data types for corresponding fields. For example, if a field in the source table is defined as a CHAR type and the corresponding field in the target table is defined as an INT type, this will lead to the GT817 error.
  Incompatible Structures: The structures of the two tables may not be compatible. This can happen if the source table has additional fields or if the field lengths differ.
  Transport Issues: If you are trying to transport a table from one system to another, the target system may not have the same data dictionary definitions or may have been modified in a way that makes the structures incompatible.
  
  Solution:
  
  Check Data Types: Review the data types of the fields in both the source and target tables. Ensure that they match exactly in terms of type, length, and any other relevant attributes.
  Adjust Table Structures: If there are discrepancies, you may need to adjust the structure of the target table to match the source table. This can involve changing field types, lengths, or even adding/removing fields.
  Use the Correct Transport Request: If the error occurs during a transport, ensure that the transport request is correctly configured and that all necessary objects are included.
  Recreate the Table: If the table is not heavily populated or if it is feasible, consider recreating the target table with the correct structure based on the source table.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version you are using, as there may be known issues or additional guidance available.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like SE11 (Data Dictionary), SE14 (Database Utility), or SE09/SE10 (Transport Organizer) to investigate and resolve the issue.
