How To Fix RSPLFOX191 - An arithmetic exception occurred

SAP Error Message - Details

• Message type: E = Error

• Message class: RSPLFOX - FOX messages: Parsing and runtime

• Message number: 191

• Message text: An arithmetic exception occurred

What causes this issue?

An arithmetic exception occurred during formula processing on HDB. The
main reasons for this are division by zero and overflow.

System Response

The system sets the result of the corresponding formula statement to
zero and continues to process the rest of the formula.

How to fix this error?

Check your formula. The behavior of the runtime systems of the
application server and the HDB are different. The formula line:
{ KEYFIG1, CHARVALUE1 } = { KEYFIG1, CHARVALUE1 } +
{ KEYFIG2, CHARVALUE2 } / { KEYFIG3, CHARVALUE4 }.
will be evaluated differently. If the value of { KEYFIG2, CHARVALUE2 }
is zero, the ABAP/V runtime system will set the result to the value of {
KEYFIG1, CHARVALUE1 }, even if the value of { KEYFIG3, CHARVALUE4 } is
zero. In this case, no arithmetic exception in the ABAP/V runtime system
occurs. The HDB runtime system will set the result to zero if the value
of { KEYFIG3, CHARVALUE4 } is zero. An arithmetic exception occurs here.
You can rewrite the formula as follows:
L_HELP = { KEYFIG3, CHARVALUE4 }.

{ KEYFIG1, CHARVALUE1 } = { KEYFIG1, CHARVALUE1 } + { KEYFIG2,
CHARVALUE2 } / L_HELP.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message RSPLFOX191 - An arithmetic exception occurred ?

  The SAP error message RSPLFOX191, which states "An arithmetic exception occurred," typically arises in the context of SAP BW (Business Warehouse) when there is an issue with calculations in a Fox formula or a query. This error can occur due to various reasons, such as division by zero, invalid data types, or unexpected null values in the data being processed.
  Causes:
  
  Division by Zero: If a calculation involves division and the denominator is zero, this will trigger an arithmetic exception.
  Invalid Data Types: If the data types used in calculations are incompatible (e.g., trying to perform arithmetic operations on strings).
  Null Values: If the data being processed contains null values that are not handled properly in the formula.
  Overflow/Underflow: If the result of a calculation exceeds the maximum or minimum limits of the data type being used.
  Incorrect Formula Logic: Errors in the logic of the Fox formula that lead to invalid calculations.
  
  Solutions:
  
  
  Check for Division by Zero: Review the Fox formula to ensure that any division operations have a valid denominator. You can use conditional statements to handle cases where the denominator might be zero.
  IF denominator <> 0 THEN
      result = numerator / denominator
  ELSE
      result = 0  // or some other default value
  ENDIF
  
  
  Validate Data Types: Ensure that all variables and fields used in calculations are of the correct data type. Convert data types if necessary.
  
  
  Handle Null Values: Implement checks for null values in your Fox formula. You can use the ISNULL function to handle nulls appropriately.
  IF NOT ISNULL(value) THEN
      result = value
  ELSE
      result = 0  // or some other default value
  ENDIF
  
  
  Review Formula Logic: Go through the logic of your Fox formula to ensure that it is correctly structured and does not lead to unexpected results.
  
  
  Debugging: Use the debugging tools available in SAP BW to step through the calculations and identify where the error occurs.
  
  
  Check Data: Review the data being processed to ensure it is clean and does not contain unexpected values that could lead to arithmetic exceptions.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error. SAP frequently updates its knowledge base with solutions for common problems.
  Documentation: Refer to the SAP BW documentation for guidelines on writing Fox formulas and handling exceptions.
  Community Forums: Engage with SAP community forums or support channels where other users may have encountered and resolved similar issues.
  
  By following these steps, you should be able to identify the cause of the RSPLFOX191 error and implement a solution to resolve it.
