• What is the cause and solution for SAP error message DDLS519 - CAST for arithmetic operand & on DB & could not be generated ?

  The SAP error message DDLS519 typically indicates an issue with the generation of a database object, specifically related to the use of the CAST function for arithmetic operands. This error can occur during the generation of database views, tables, or other database objects when the SQL statement involves arithmetic operations that cannot be properly cast or converted.
  Cause:
  
  Data Type Mismatch: The error often arises when there is a mismatch in data types during arithmetic operations. For example, trying to perform arithmetic on incompatible data types (e.g., trying to add a string to a number).
  Database Compatibility: The SQL syntax or functions used may not be compatible with the underlying database system (e.g., HANA, Oracle, SQL Server).
  Invalid SQL Syntax: There may be an issue with the SQL syntax itself, such as incorrect use of parentheses or operators.
  Database Constraints: Certain constraints or rules in the database schema may prevent the operation from being executed.
  
  Solution:
  
  Check Data Types: Review the data types of the operands involved in the arithmetic operation. Ensure that they are compatible and can be cast to a common type.
  Modify SQL Statement: If the SQL statement is generated by a view or a program, consider modifying it to ensure that all operands are of compatible types. Use explicit casting where necessary.
  
  Example: Instead of column1 + column2, use CAST(column1 AS DECIMAL) + CAST(column2 AS DECIMAL).
  
  
  Review Database Compatibility: Ensure that the SQL syntax used is compatible with the database you are working with. Refer to the database documentation for the correct syntax.
  Check for Constraints: Review any constraints or rules in the database schema that might be affecting the operation. Adjust the schema or the SQL statement accordingly.
  Debugging: If the error occurs during a specific transaction or program execution, use debugging tools to trace the SQL statement being executed and identify the exact cause of the error.
