Selecting the values "Yes" or "No" has an impact only on the entry of dimension types in BP invoices and within the payment lines.
If a dimension type has its value set to 'No', the Dimension field of the dimension type is displayed in the BP invoices header but cannot be entered. The initialization is, as usual, carried out by the default dimension codes.
The dimension is not displayed in the BP invoice and payment lines but it follows the usual operation and it is initialized by the default dimension setups.
