Summary:

Content (please ensure you mask any confidential information):

Hi,

We are creating a Fast Formula to show both manager and employee performance rating (2 values), so far we have done the following for the manager:

DEFAULT_DATA_VALUE FOR HRA_EVAL_GOAL_RATING_FC_GOAL_ID IS 0
DEFAULT_DATA_VALUE FOR HRG_GOALS_GOAL_ID IS 0
DEFAULT_DATA_VALUE FOR HRG_GOALS_ATTRIBUTE2 IS ' '

I = 1 
L_RETURN_VALUE = 0
J = 1
  WHILE HRG_GOALS_GOAL_ID.EXISTS(J) LOOP
  (
    IF HRG_GOALS_GOAL_ID[J] = HRA_EVAL_GOAL_RATING_FC_GOAL_ID[I] THEN
    (
      L_RETURN_VALUE = L_RETURN_VALUE + TO_NUMBER(HRG_GOALS_ATTRIBUTE2[J])
