Summary :
When using transaction FB75 to post a credit memo, no official document number is generated, and error message 8A-770 appears. This issue pertains specifically to VAT (introduced in India) scenarios within SAP, where the system fails to differentiate between interstate and intrastate transactions for assigning unique official document numbers. To resolve this, users must implement prerequisite notes 831870, 833318, 832503, and 833991 and apply a specified code correction to ensure compliance with the VAT 2005 requirements for transaction FB75.
