• What is the cause and solution for SAP error message DDLS387 - Division x/y is only allowed for float numbers ?

  The SAP error message DDLS387, which states "Division x/y is only allowed for float numbers," typically occurs in the context of ABAP programming or when working with database views or calculations in SAP. This error indicates that a division operation is being attempted with data types that are not compatible for division, specifically when the operands are not of a floating-point type.
  Cause:
  
  Data Type Mismatch: The most common cause of this error is that the operands involved in the division operation are not of type FLOAT or DECIMAL. For example, if you are trying to divide two integers or two strings, this error will occur.
  Implicit Type Conversion: Sometimes, implicit type conversion may not occur as expected, leading to this error when performing arithmetic operations.
  Database Views: If this error arises in the context of database views, it may be due to the way fields are defined in the view or the underlying tables.
  
  Solution:
  
  
  Check Data Types: Ensure that both operands in the division operation are of type FLOAT or DECIMAL. You can do this by checking the data types of the variables or fields involved in the division.
  
  If they are not, consider converting them to a compatible type using appropriate ABAP functions or casting.
  
  Example:
  DATA: lv_num1 TYPE i,
        lv_num2 TYPE i,
        lv_result TYPE f.
  
  lv_result = lv_num1 / lv_num2.  " This will cause DDLS387 if lv_num1 or lv_num2 is not float
  Change to:
  lv_result = lv_num1 / lv_num2.  " Ensure lv_num1 and lv_num2 are float or convert them
  
  
  Use Explicit Casting: If you are working with integers or other types, you can explicitly cast them to FLOAT before performing the division.
  lv_result = CAST f( lv_num1 ) / CAST f( lv_num2 ).
  
  
  Review Database Views: If the error occurs in a database view, check the definitions of the fields involved in the division. Ensure that the fields are defined with appropriate data types that support division.
  
  
  Debugging: If you are unsure where the error is occurring, use debugging tools in SAP to step through the code and identify the exact line causing the issue.
  
  
  Related Information:
  
  ABAP Data Types: Familiarize yourself with the different data types in ABAP, especially FLOAT, DECIMAL, and INTEGER.
  Arithmetic Operations: Review the rules for arithmetic operations in ABAP, particularly how different data types interact.
  SAP Documentation: Consult the official SAP documentation for more details on data types and arithmetic operations in ABAP.
  
  By ensuring that the operands in your division operation are of compatible types, you should be able to resolve the DDLS387 error.
