How To Fix BRAIN_DEV031 - Row (&1) in formula "&2" uses an operator that is not supported

SAP Error Message - Details

• Message type: E = Error

• Message class: BRAIN_DEV - BRAIN messages (for use by development)

• Message number: 031

• Message text: Row (&1) in formula "&2" uses an operator that is not supported

What causes this issue?

The cell (&V1&) uses formula "&V2&". Either directly, or indirectly with
formula exception aggregation, this formula contains one of the
operators listed below.
The operators that are not supported are:
[SUMCT] Total
[SUMGT] Grand total
[SUMRT] Report total
[%CT] Percentage of total
[%GT] Percentage of grand total
[%RT] Percentage of report total
For these operators, the results are neither predictable nor well
defined in the context of the formula exception aggregation.

System Response

As of Release 703/730, the formula is calculated as if there were no
operator. In lower releases, the system just displays a message warning
that the formula will be calculated but that the results will not be
predictable.

How to fix this error?

The above-mentioned operators are still supported in formulas that use
the results of formula exception aggregation. Examples:
<ZH>CNT( SUMCT Operand ) for calendar day</>
The query generation reduces this formula to <ZH>CNT( Operand ) for
calendar day</>. This does not change the result.
<ZH>SUM( SUMCT Operand ) for calendar day</>
The query generation reduces this formula to <ZH>SUM( Operand ) for
calendar day</>. This changes the result. The expected result can be
achieved by changing the formula in the query definition to <ZH>SUMCT(
Operand ) * SUM ( Operand ) for calendar day</>.

Procedure for System Administrators

• What is the cause and solution for SAP error message BRAIN_DEV031 - Row (&1) in formula "&2" uses an operator that is not supported ?

  The SAP error message BRAIN_DEV031 indicates that there is an issue with a formula in a report or query where an unsupported operator is being used. This error typically arises in the context of SAP BusinessObjects or SAP BW (Business Warehouse) when working with calculated fields or formulas in queries.
  Cause:
  The error occurs when:
  
  An operator that is not supported in the context of the formula is used. This could be due to using mathematical operators, logical operators, or functions that are not valid for the data type or context.
  The formula syntax is incorrect, leading to the use of an operator that the system cannot interpret.
  The formula is referencing fields or variables that are incompatible with the operation being performed.
  
  Solution:
  To resolve the BRAIN_DEV031 error, you can take the following steps:
  
  
  Review the Formula: Check the formula specified in the error message (indicated by "&2"). Ensure that all operators used are valid for the data types involved. Common operators include +, -, *, /, and logical operators like AND, OR.
  
  
  Check Data Types: Ensure that the fields or variables being used in the formula are compatible with the operators. For example, you cannot perform mathematical operations on string data types.
  
  
  Simplify the Formula: If the formula is complex, try breaking it down into simpler components to identify which part is causing the issue.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific version you are using to understand the supported operators and functions for formulas in your context.
  
  
  Test in Isolation: If possible, test the formula in isolation or in a different environment to see if the error persists. This can help identify if the issue is with the formula itself or with the data context.
  
  
  Seek Help from SAP Community: If you are unable to resolve the issue, consider reaching out to the SAP community forums or support for assistance. Provide them with the specific formula and context for better guidance.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address known issues or provide updates related to this error.
  SAP Community: Engage with the SAP Community for insights from other users who may have encountered similar issues.
  Training and Documentation: Consider reviewing training materials or documentation related to SAP BW and BusinessObjects to better understand formula creation and limitations.
  
  By following these steps, you should be able to identify and resolve the cause of the BRAIN_DEV031 error in your SAP environment.
