Update custom filed values based on selecting custom filed Values.

[PRAMOD KUMAR REDDY KASIREDDY]

We Have custom fields called 1) initial Impact and 2) initial Probability and 3) initial rating
The filed values are alpha and numeric:-

1- Very Low – 10%

2- Low – 30%

3- Medium – 50%

4- High- 70%

5- Very High- 90%
Now the requirement is by selecting the Values of Initial Impact and initial Probability. Then the value of Initial rating should be generated automatically.

]

def impactFieldValue = getFieldByName('Initial Impact').value as String
def probabilityFieldValue = getFieldByName('Intial Probability').value as String

def rating = ratingMatrix[impactFieldValue][probabilityFieldValue]
def ratingField = getFieldByName('Initial Rating')
ratingField.setFormValue(rating)

This is the formula i'm using in Behaviors.

Pls Help on this.
