Validation in Postal Code in Vendor / Customer Master

                Postal code is a unique data more helpful to track any address.     But in customer / vendor Master data often either  user skips this fields or fill something irrelevant if it supposed to be mandatory.     To create a validation rule for postal code I suggest a simple solution which an ABAPER can do without much effort.

                The first 2 digit of the postal code represents the State as given below :

Except 90- 99  all the ranges are possible values in postal code.    The “ Region”  field is used to capture the State.    The Pincode already entered by user can be verified by the Region selected by the user . 
For example  

First 2 digit of Pincode 60,61,62,63,64  are possible values for Region = 22  ( ie. Tamilnadu )

This simple validation will be more useful even though not cent percent accuracy to some extent validate the data entered.  

I invite all to improve the validation further towards more accuracy.
