• What is the cause and solution for SAP error message DDVIDB084 - For function AVG, INT8 as argument type is not supported ?

  The SAP error message DDVIDB084 indicates that there is an issue with the use of the AVG function in a database query where the argument type INT8 (which represents a 64-bit integer) is not supported. This error typically arises when you are trying to calculate the average of a field that is defined as an INT8 type in the database.
  Cause:
  The primary cause of this error is that the AVG function in the context of the database you are using does not support INT8 as an argument type. The AVG function is generally used to calculate the average of numeric values, but certain database systems may have restrictions on the data types that can be used with this function.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Cast the Data Type: Convert the INT8 value to a supported data type, such as FLOAT or DECIMAL, before applying the AVG function. For example:
  SELECT AVG(CAST(your_column AS FLOAT)) FROM your_table;
  
  
  Check Database Documentation: Review the documentation for your specific database system to understand the supported data types for the AVG function. This will help you identify the correct data type to use.
  
  
  Modify the Query: If casting is not an option or if it does not resolve the issue, consider modifying your query logic to avoid using AVG on INT8 fields directly.
  
  
  Data Type Change: If feasible, consider changing the data type of the column in the database schema from INT8 to a type that is compatible with the AVG function.
  
  
  Consult with Database Administrator: If you are unsure about making changes to the database schema or queries, consult with your database administrator or a developer who is familiar with the database system you are using.
  
  
  Related Information:
  
  Database Compatibility: Different databases (e.g., SAP HANA, Oracle, SQL Server) may have different rules regarding data types and functions. Ensure that you are aware of the specific requirements of the database you are working with.
  Performance Considerations: When casting data types, be mindful of performance implications, especially if you are working with large datasets.
  Testing: After making changes to your query, test it thoroughly to ensure that it produces the expected results without introducing new errors.
  
  By following these steps, you should be able to resolve the error and successfully calculate the average of the desired values.
