Changed prices (from the price change document) DO NOT take effect on already created issue documents. When issuing an article, the sale prices valid AT THE MOMENT the invoice is presented are recorded in the line.
	Price changed documents are created either manually (see Price Change) or automatically based on data in the receiving document or transfer document for transfers to a warehouse where posting by retail price has been selected (see Creating Price Change Documents).

If the retail price is changed when posting stock by retail price and the tax rate remains the same, the relative share of the change of the retail price will affect the changed gross margin and changed value of included VAT.

This is why you must also post price change documents at the warehouses where the value of stock is posted by retail price.

Example:

A calculation of the effects the change of the retail price from 216 to 240 EUR for 1 piece of the article in stock.

Calculation:

- (CRP) Change of retail price: 240 - 216 = 24

- (CTB) Change of tax base = change_of_retail_price/tax_factor: 24/1.2 = 20

- (CVAT) Change of included VAT = CRP* tax_factor/tax_factor: 24 * 0.2/1.2 = 4

- (CGM) Change of included gross margin GM= CRP - CVAT: 24 - 4 = 20

Changes in the tax rate (whether the retail price is changed or not) and consequently changes in the value of included VAT CANNOT be posted with this document! In this case, the change of included VAT must be manually posted.
