We are a small business in the US. We have a posted sales invoice with the incorrect line price.
I changed my Role Center to Small Business and tried to Correct the Posted Sales Invoice. - https://msdn.microsoft.com/en-us/library/dn275886(v=nav.90).aspx
I then get the following error:
"Sales VAT Account must have a value in Tax Posting Setup: Tax Bus. Posting Group=, Tax Prod. Posting Group=. It cannot be zero or empty."
I recall our partner recommending and removing all tax posting setup on implementation earlier last year, i.e. the Tax Posting Setup is only one line:
Tax Bus. Posting Group is blank
Tax Prod. Posting Group is blank
Tax % is 0
Tax Calculation Type is Sales Tax
We don't use or have any tax functionality set up.
According to other posts it is recommended to leave tax bus posting group, tax prod posting group blank.
I've tried adding a dummy account to Sales VAT Account in tax posting setup but I get another error
"Sales VAT Account must be entered on the tax jurisdiction line when Tax Calculation Type is Sales Tax."
Tax jurisdiction is not setup and I'm reluctant to proceed without knowing why this was not setup during implementation.
Two questions:
What must I do to allow me to Correct Posted Sales Invoices?
What is a reason a partner would advise not using NAV tax functionality? I see in another post (community.dynamics.com/.../187197) that recommends never leaving tax setup blank.
