Defaulting Descriptive Flexfield Segment Values

Hi

Our customer are setting up a new Person Extra Information Type which will hold the sick pay scheme the employee belongs to. They want this to be defaulted based on a value held as a segment (‘grade type’) in the Additional Grade Details DFF, details as follows:

IF ‘grade type’ = ‘NPS’ THEN

    Sick Pay Scheme = ‘NPS Scheme’

ELSIF ‘grade link type’ = ‘NHS’ THEN

    Sick Pay Scheme = ‘NHS Scheme’

ELSE

    Sick Pay Scheme = ‘Standard Scheme’

END IF

Obviously the complication is that the correct default can only be determined when the grade is entered/updated on the assignment form.

I understand some sort of customization will be requied but would like advice on the best approach to take.
