3536679 - Wrong GSTIN number is getting picked in the Customer Invoice document and splitting the invoice (For Country India)

There is one company code with two GSTIN numbers (seller tax numbers) maintained for states A and B in country India. During outbound delivery, when the ship-from location is A, the system incorrectly picks up GSTIN numbers for both A and B. As a result, the invoice splits into separate records. 

Please note: A and B are the States in country India. And this KBA is only applicable for India region.

1. Navigate to the Customer invoicing work center.
2. Go to the Invoice request sub view.
3. Filter it with 'to be Invoiced'
4. Search for the relevant document ABC, select it and choose Invoice
5. Under Invoices there will be two invoices.
6. Try to select both and give Split analysis, the GST Numbers for unit A and B will be visible. Reference: below mentioned image.
7. 

The reason why the Customer Invoice 'ABC' is picking multiple GST Identification number is that Sales orders created by copying from old orders. 

While creating a Customer Invoice from an invoice request/Sales orders, the system checks for any data inconsistencies in predecessor documents. In this case while attempting to create a customer invoice with inconsistent data, the system will be splitting the invoice. So ideally when creating the documents as the copy of predecessor documents try to check the sales units and the data which is being copied from the previous document to avoid any inconsistencies. 

1. Create a new sales order, 'PQR,' by copying the existing sales order, 'TUV.'
2. During the creation of sales order 'PQR,' delete the seller and reassign the same seller in the "Involved Parties" section.
3. This step ensures the system retrieves the latest seller tax number (GSTIN) from the database instead of using the data from the copied sales order, 'TUV.'
4. Complete the subsequent processes, including outbound delivery, PGI, and other required steps.
5. Verify that the invoice no longer splits, and that the seller tax number (GSTIN) is accurate.
