To comply with this requirement, Munim provides an option to enforce 6-Digit HSN validation at the company level.
How to Enable 6-Digit HSN Validation
Go to the Client Setting module.
Select and edit the company for which you want to apply this setting.
Under the Other Applicability section, enable the option 6D HSN.

Validation Behavior
Once the 6-Digit HSN option is enabled:

Important Note
- This setting should be enabled only for companies with AATO above ₹5 crore
