Some entries didnt reflacted in GSTR-3B report

I’m facing an issue with the GSTR-3B report in ERPNext.

I have multiple Purchase Invoices with CGST + SGST taxes applied. However, only some of these invoices are appearing in the GSTR-3B report, while others are missing.

Key points:

  • None of the invoices are Opening Invoices

  • None of them use an Item Tax Template

  • Most other details (company, supplier, posting date, tax structure, etc.) are the same across both visible and missing invoices

  • All invoices are submitted

erpnext: 15.78.1
frappe: 15.80.0
hrms: 16.0.0-dev
india_compliance: 15.22.0
payments: 0.0.1

Despite the above, some invoices still do not reflect in the GSTR-3B report.

Has anyone faced a similar issue, or can suggest what other factors could cause certain Purchase Invoices to be excluded from GSTR-3B?

Any pointers or debugging steps would be appreciated.
