FSCM Credit Limit Formula

[S0020564316]

Hi Gurus,

We have a request from Business to Calculate Credit Score and Limit based on few criteria.
Based on Calculated Score, a Risk Class will be assigned which will be covered using standard config. (From Score, To score in Risk Class definition).
Score Calculation:- CreditSafe Score + CRM Rating (internal; user will change the field value in BP master) + will change based on Average Payment Delay Arrears (X) (ranging from 0 to 60).
The ask is: to have different score based on different value of X.
So, for example:
X = 0; Score = 35
X = 10; Score = 25
X = 60; Score = 0.
So, they want different score based on different values of X. In this case, 35 different scores for 60 different values of X.

Further, based on this Score, they want different Limit Multiplier against different Scores. (A multiplier spread of 35 points against a Score spread of 55 points)
Example:
Score = 46; Multiplier = 1.0
.
.
.
Score = 60; Multiplier = 1.15
Score = 61; Multiplier = 1.16
Score = 62; Multiplier = 1.17
.....Similarly, if Score = 100; Multiplier = 1.35

Can we achieve this via the Standard Formula engine?

Any help with this regards is helpful.
Thanking you in anticipation

Regards,
Aditya
