In interview Central, when we try to rate a candidate using a rating scale with decimal values, the rating does not save. Instead the rating is changed to the nearest whole number rating.
SAP SuccessFactors Recruiting Management
Decimal values are not supported in the rating scale for Interview Central.
This is currently expected behavior. Decimal values are not supported for the rating scale in Interview Central, only whole numbers are. An internal enhancement request has been raised to improve this feature in future releases and allow decimal values to be supported. To follow this enhancement, please contact you CSM and provide them with the following internal ticket number RCM-55327.
