How To Fix GA851 - Field overflow when calculating the receiver tracing factor

SAP Error Message - Details

• Message type: E = Error

• Message class: GA - Allocations

• Message number: 851

• Message text: Field overflow when calculating the receiver tracing factor

What causes this issue?

During processing of segment &V1& a field overflow occurred when
calculating the receiver tracing factor (BCD_FIELD_OVERFLOW). The
current parameters of the calculation formula are:
Receiver tracing factor on the database : &V2&
Rec. weighting factor in the segment (multiplicator) : &V3&
Rec. weighting factor in the segment (divisor) : &V4&

System Response

The system cannot continue to process the cycle effectively.
In the program, the receiver tracing factor is multiplied by its
weighting factor and divided using the divisor (this gives the number of
decimal places). To avoid rounding errors, the system first executes the
multiplication. This means that if the product of &V2& and &V3& is
greater than the RSHA variable, this short dump occurs.
The maximum field size for RSHA is 15 (including 3 decimal places)
(that is, 999999999999.999-).

How to fix this error?

Change the receiver tracing factor so that the product of the tracing
factor and the weighting factor do not exceed the maximum value
mentioned above.

• What is the cause and solution for SAP error message GA851 - Field overflow when calculating the receiver tracing factor ?

  The SAP error message GA851, which indicates a "Field overflow when calculating the receiver tracing factor," typically occurs in the context of the SAP Controlling (CO) module, particularly when dealing with cost allocation and tracing factors in internal orders or cost centers.
  Cause:
  The error is usually caused by one of the following issues:
  
  
  Data Type Limitations: The calculation of the receiver tracing factor may exceed the maximum value that can be stored in the designated field. This can happen if the input values (e.g., costs, quantities) are too large or if there are too many decimal places involved in the calculation.
  
  
  Configuration Issues: Incorrect configuration in the cost allocation settings or in the master data of cost centers or internal orders can lead to unexpected results during calculations.
  
  
  Rounding Issues: If the rounding settings are not properly configured, it may lead to values that exceed the field limits during calculations.
  
  
  Solution:
  To resolve the GA851 error, you can take the following steps:
  
  
  Check Input Values: Review the values being used in the calculation. Ensure that they are within reasonable limits and do not exceed the maximum allowable values for the fields involved.
  
  
  Adjust Configuration: 
  
  Review the configuration settings for cost allocation and tracing factors in the SAP system. Ensure that they are set up correctly according to your business requirements.
  Check the settings for the relevant cost centers or internal orders to ensure they are correctly defined.
  
  
  
  Rounding Settings: 
  
  Check the rounding settings in the system. Adjust them if necessary to ensure that calculations do not lead to overflow.
  
  
  
  Data Cleanup: If there are any inconsistencies or errors in the master data (e.g., cost center or internal order data), correct them to ensure that they do not contribute to the overflow issue.
  
  
  SAP Notes and Support: If the issue persists, check for any relevant SAP Notes that may address this specific error. You can search the SAP Support Portal for updates or patches that may resolve the issue.
  
  
  Testing: After making adjustments, perform tests to ensure that the error does not occur again. Monitor the calculations closely to identify any further issues.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as KSB1 (Cost Centers: Actual Line Items) or KOB1 (Orders: Actual Line Items) to analyze the data involved in the calculations.
  SAP Documentation: Refer to SAP Help documentation for detailed information on cost allocation and tracing factors.
  User Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, and solutions shared.
  
  If you continue to experience difficulties, consider reaching out to your SAP support team or a consultant with expertise in SAP Controlling for further assistance.
