VAT Posting Error flagged in Purchase Order

We have just started using Business Central at our organisation, and while creating a Purchase Order, we have repeatedly been getting an error message related to the VAT Business Posting Group (Please see attached image). As a part of the troubleshooting process, I have ensured that the DOMESTIC VENDOR + STANDARD VAT+ NORMAL METHOD combination exists in the VAT Posting set up, and that the Vendor and Resource have been assigned to the respective Posing groups. However, the error message has persisted- I would appreciate any help on rectifying this.

Further details about the error:
