• What is the cause and solution for SAP error message SY069 - First parameter not numeric ?

  The SAP error message SY069 ("First parameter not numeric") typically occurs in ABAP programs when a function or operation expects a numeric value as its first parameter, but it receives a non-numeric value instead. This can happen in various scenarios, such as when performing arithmetic operations, calling certain functions, or using specific statements that require numeric input.
  Causes:
  
  Data Type Mismatch: The variable or field being passed as the first parameter is not of a numeric type (e.g., it might be a character string or a structure).
  Incorrect Function Call: A function or method that expects a numeric input is being called with a non-numeric argument.
  Uninitialized Variables: A variable that is expected to hold a numeric value has not been initialized properly, leading to it containing a non-numeric value.
  Data Conversion Issues: If there is an implicit or explicit conversion happening, it might fail if the data cannot be converted to a numeric type.
  
  Solutions:
  
  
  Check Data Types: Ensure that the first parameter being passed is of a numeric type (e.g., I, F, P). You can use the DATA statement to define the variable correctly.
  DATA: lv_number TYPE i.
  
  
  Debugging: Use the ABAP debugger to inspect the values of the variables being passed to the function or operation. This will help identify if the variable is indeed numeric or if it contains unexpected data.
  
  
  Initialization: Make sure that all variables are properly initialized before they are used in calculations or function calls.
  
  
  Explicit Conversion: If you are dealing with string representations of numbers, use conversion functions like CONVERT or CAST to ensure that the data is in the correct format.
  DATA(lv_string) = '123'.
  DATA(lv_number) TYPE i.
  lv_number = lv_string.  " Ensure lv_string is numeric
  
  
  Error Handling: Implement error handling to catch and manage situations where non-numeric values might be passed inadvertently.
  
  
  Related Information:
  
  ABAP Data Types: Familiarize yourself with the different data types in ABAP and their characteristics.
  Function Documentation: Review the documentation for the specific function or method being called to understand its parameter requirements.
  SAP Notes: Check SAP Notes for any known issues or patches related to the error message SY069.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
