• What is the cause and solution for SAP error message TT099 - & is a structure, not a table ?

  The SAP error message TT099 typically indicates that there is an issue related to the data structure being referenced in your ABAP program or configuration. The message "is a structure, not a table" suggests that the program is trying to perform an operation that is only valid for database tables, but the object in question is a structure.
  Cause:
  
  Incorrect Data Type: The program is attempting to access or manipulate a structure as if it were a database table. This can happen if you mistakenly use a structure in a context where a table is expected, such as in a SELECT statement or a loop that expects a table.
  Misconfiguration: If you are working with a custom development or a specific configuration, it might be that the structure was incorrectly defined or used in a way that is not compatible with the expected operations.
  
  Solution:
  
  Check Data Definitions: Review the ABAP code where the error occurs. Ensure that you are using the correct data types. If you need to work with a table, make sure you are referencing a table type or a database table instead of a structure.
  Modify Code: If you need to retrieve data from a database table, ensure you are using a proper SELECT statement with a table name. If you need to work with a structure, ensure that you are using it in a context that is appropriate for structures (e.g., assigning values, passing to function modules).
  Use Appropriate Operations: If you need to convert a structure to a table format, you may need to create an internal table of the appropriate type and then populate it with data from the structure.
  
  Related Information:
  
  ABAP Data Types: Familiarize yourself with the differences between structures and tables in ABAP. Structures are used to define a fixed set of fields, while tables are used to store multiple records of data.
  Debugging: Use the ABAP debugger to step through the code and identify where the error occurs. This can help you understand how the structure is being used incorrectly.
  Documentation: Refer to SAP documentation or community forums for examples of how to correctly use structures and tables in ABAP.
  
  By addressing the data type mismatch and ensuring that you are using the correct operations for structures and tables, you should be able to resolve the TT099 error.
