Wrong GST Registration Number - Detailed GST Ledger Entries

Dear Experts,

We have observed an issue in D365 Business Central related to the GST Registration Number in the Detailed GST Ledger Entries.

We have posted multiple Purchase Invoices and Sales Invoices. We have verified the following:

Customer and Vendor GST Registered Numbers are correct in their respective masters.
The GST Registered Number shown on the posted documents is correct.
Customer Ledger Entries and Vendor Ledger Entries also show the correct GST Registered Number.
However, in the Detailed GST Ledger Entries, an incorrect and irrelevant GST Registered Number is being populated for more than 200 transactions.

We further investigated the incorrect GST Registered Number and found that it belongs to the Order Address of one particular Vendor.

The issue is that:

The respective Vendor's Order Address was not selected in these transactions.
The affected transactions belong to different Vendors and Customers and are completely unrelated to this GST Registered Number.
The same GST Registered Number is repeatedly flowing into the Detailed GST Ledger Entries for more than 200 unrelated transactions.
This GST Registered Number is not relevant to the actual Customer/Vendor involved in those transactions.

Since the Customer/Vendor masters, posted documents, and Customer/Vendor Ledger Entries contain the correct GST Registered Numbers, we would like to understand from which source/table/logic the Detailed GST Ledger Entry is picking up this incorrect GST Registered Number.

Hello Dharmesh,

This is not expected standard behavior. In the India localization, the GSTIN stored in Detailed GST Ledger Entries should represent the GST registration applicable to that specific posted transaction; Microsoft documents that the vendor master contains the normal GST Registration No., while a Vendor Order Address can also contain its own GST Registration No., which is relevant only when that address is actually used for the transaction. Detailed GST Ledger Entries are subsequently used for statutory processes such as GST reconciliation, where Microsoft specifically matches the Supplier GSTIN, so an unrelated Order Address GSTIN appearing across 200 different vendors/customers strongly indicates a posting/localization defect or corrupted posting context, rather than normal setup behavior. I would reproduce one transaction in a production-copy sandbox, confirm the GSTIN on the document immediately before posting, test on the latest BC cumulative update, and temporarily disable any GST-related customizations/extensions; if the wrong GSTIN is still written, raise a Microsoft support case with examples because the public documentation does not expose a setup that would intentionally make one vendor’s Order Address GSTIN flow into unrelated Detailed GST Ledger Entries. I would also not directly edit the 200 posted GST entries, because they feed statutory GST reconciliation/reporting; any historical correction should be done using a Microsoft-supported correction procedure after the root cause is confirmed.
