You can change VAT operation code manually in the Russian version of Microsoft Dynamics AX 2012 R3, Microsoft Dynamics AX 2012 R2, and Microsoft Dynamics AX 2009 SP1

1. Lawmakers had changed the list of operation codes during the year 2015, which is why there is a need to change the codes in Facture journals and Sales or Purchases books created in the first quarter 2015. From the other side, not all operation codes may be identified and created automatically.
The Operation code field in Sales or Purchases books are automatically fulfilling based on the value of the same name field from the Facture journal when the books are creating.

2. The Code field (Type of operation code) is added in the Parameters of VAT process form in order to have the possibility to use different codes for different operation types. (Accounts payable \Periodic\Purchase book\Parameters of VAT process and Accounts receivable \Periodic\Sales book\Parameters of VAT process as well)

3. The feature provides the possibility to change the Operation code manually in Facture journal and in Sales or Purchases books.
Using the Facture operationcodes menu button on the Facture journal form or inside the Function button on the Sales\ Purchases books journal form, you can define the old and new values for the operation codes, which should be changed, and the criteria for lines selecting for the changing procedure. (Enter the old and new operation code values in the Operationcode- From field and in the Operation code- Replacewithfield respectively)

To specify the criteria more detailed, you can in standard query by using the Select button.
To confirm the new operation codes values, you should mark the confirmed lines in the Mark field or use the Mark all button.

4. New explanation came from consulters providing the city seminar: Independent on the fact that only a part of VAT should be a taken as VAT deduction, the hall sum of the facture must be reflected in column 15 of a purchase book. This approach is realized in Microsoft Dynamics AX 2009 SP1.
For Microsoft Dynamics AX 2012 R2 and Microsoft Dynamics AX 2012 R3, a separate feature will be realized. Please see hotfix KB3078022 .
