Performance Rating fast formula that references questionnaire scores

Summary:

Hi all,

We have a scored questionnaire in one of our Performance Documents. Can we use a fast formula to reference the question scores in order to provide an overall calculated rating?

I have reviewed this document but I cannot see any reference to questionnaire DBIs, although I have found some questionnaire DBIs in the UI.

Eg.

HRA_EVAL_QUESTION_QUESTION_CODE
HRA_EVAL_QUESTIONNAIRE_QUESTIONNAIRE_CODE
HRA_EVAL_QUESTION_SCORE
HRA_EVAL_QUESTIONNAIRE_MAX_POSSIBLE_SCORE
HRA_EVAL_QUESTIONNAIRE_TOTAL_SCORE

Thanks

Edward
