Is your feature request related to a problem? Please describe.

While using the india_compliance app to file GSTR-1, I noticed a couple of areas where the user experience could be improved, especially in relation to HSN code validation:

Observations:

1. HSN Error Logs Lack Details

When there's an invalid HSN code (e.g., RET191349), the error summary just says "The HSN code entered is not valid", without mentioning (the errorerd HSN is available in the error report from the portal):

• Which HSN code is problematic
• Which invoice or item it relates to This makes it hard to trace and fix the issue, especially in bulk filings.

2. Unclear Flow for Updating HSN on Already Billed Items

• In cases where HSN codes are corrected after invoices have been generated but before filing, it's unclear:
• Whether editing the item master is sufficient
• Whether invoices need to be cancelled and regenerated

3. Or if there’s a recommended/supported workflow to update the GSTR-1 JSON with the corrected HSN codes

Describe the solution you'd like

1. Include HSN code, invoice number, and item name in the error summary view to make it easier to pinpoint errors.
2. If possible, provide guidance or tooling for handling post-billing HSN code corrections, especially for unfiled but submitted invoices.

Describe alternatives you've considered
