GST Number Validation while creating/updating Suppliers

Summary:

When users are trying to Create/Update Suppliers, at the address level our expectation is to have a validation to check whether the users are providing correct GSTIN based on below validations:

1. The first two digits of GSTIN should be as per State code. -> if there any mismatch between State and State code of an entered address, system should give warning/error

2. Next 10 digits should match the PAN number entered for such Supplier. -> system should give warning/error if there any mismatch between PAN number entered in the supplier profile and these 10 digits.

3. 13th & 15th digit can be alpha-numeric.
