Please help me with this VAT error for a PO prepaymentPO-prepayment-error.JPG

Here is the VAT Setup:

I have spent hours trying to understand VAT setup, and various other postings similar to this on here - and am getting no where.

Can anyone give me a simple answer - without referring to a whitepaper or documentation - as both are very complicated reading!

Thanks,

I have the same question (0)

    The system is expecting the VAT calculation type as Normal VAT in the line where VAT Bus. Posting group is blank and VAT Prod. Posting Group is blank.

    May be the 1st line in your screenshot as I couldn't see VAT Prod. Posting Group in the screenshot.

    Hi,

    If it is a Purchase Order then ideally there should be some VAT Business Posting Group assigned to the Vendor and similarly some VAT Product Posting Group to the Item/GL Account even if it is zero VAT. As it will help in VAT statements.

    But still you can overcome the error by changing the record (with empty VAT Business Posting Group and empty VAT Product Posting Group; first one in image) in VAT Posting Setup to Normal VAT rather than Sales Tax.

    Hello Bilal - Thank you for your suggestion.  I am trying to make this change - however Business Central is not allowing the change and I receive this message - Validation Results

    You cannot change the VAT posting setup because it has been used to generate VAT entries. Changing the setup now can cause inconsistencies in your financial data.

    Could you please offer a next suggestion to resolve that?

    Hi,

    Yes this is standard error that comes when you are trying to change VAT Calculation Type for a combination that already has some VAT entries.

    If this PO has already some lines posted or some prepayments processed? Or any other details about this document, please share

    Yes - there is a Vendor CR Memo.   What do you recommend I do?
