How To Fix BRAIN_DEV066 - Operations in SAP HANA/BWA and calculation without high precision

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 066

• Message text: Operations in SAP HANA/BWA and calculation without high precision

What causes this issue?

The query contains exception aggregations or currency/unit conversions
or structure elements that support conditions calculated in SAP HANA
DB/BWA for which calculation with high precision is not requested
according to the query and InfoObject settings. These exception
aggregations or currency/unit conversions or conditions on those
structure elements will therefore be calculated without high precision
if they are not calculated in SAP HANA DB/BWA.
These exception aggregations or currency/unit conversions or appropriate
conditions on those structure elements can be calculated in the SAP HANA
DB/BWA however.
SAP HANA DB/BWA always uses decimal floating point numbers with 34
decimal places (decfloat34, long decfloat). This means that SAP HANA
DB/BWA calculates with high precision without considering the query or
InfoObject setting.

System Response

For all exception aggregations apart from "Counter for All Detailed
Values" and "Counter for All Detailed Values That Are Not Zero, Null, or
Error" and currency/unit conversions and conditions, the result might
differ slightly if the exception aggregation or currency/unit conversion
or condition is calculated in SAP HANA DB. In very rare cases, a numeric
overflow might occur.

How to fix this error?

To ensure that the query result does not differ, and that no numeric
overflow occurs, you can select calculation with high precision in the
query or InfoObject settings.

• What is the cause and solution for SAP error message BRAIN_DEV066 - Operations in SAP HANA/BWA and calculation without high precision ?

  The SAP error message BRAIN_DEV066 typically indicates that there is an issue related to the precision of calculations in SAP HANA or SAP BW Accelerator (BWA). This error can occur when operations are performed that require high precision, but the system is unable to provide it due to configuration or data type limitations.
  Cause:
  
  Data Type Limitations: The error may arise if the data types used in calculations do not support the required precision. For example, using a FLOAT or REAL data type instead of DECIMAL can lead to precision issues.
  Configuration Settings: The settings in the SAP HANA or BWA environment may not be configured to handle high-precision calculations.
  Aggregation Issues: If the system is trying to aggregate data that requires high precision but is configured to use lower precision, this error can occur.
  Incompatible Operations: Certain operations may not be compatible with the precision settings of the data being processed.
  
  Solution:
  
  Check Data Types: Review the data types used in your calculations and ensure that they are appropriate for high-precision operations. Consider using DECIMAL types where necessary.
  Adjust Configuration: Look into the configuration settings of your SAP HANA or BWA system. Ensure that the settings allow for high-precision calculations.
  Modify Queries: If you are using SQL queries or calculation views, modify them to ensure that they are designed to handle high precision. This may involve changing the way aggregations are performed or how data types are defined.
  Review Calculation Logic: Ensure that the logic used in calculations is appropriate for the data being processed. Avoid operations that may lead to loss of precision.
  Consult Documentation: Refer to SAP documentation for specific guidelines on handling precision in calculations within HANA and BWA.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide updates and patches that could resolve the issue.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Performance Considerations: Be aware that high-precision calculations can impact performance. Ensure that the need for precision is justified by the business requirements.
