Price list update
A price list can be updated using related option 16='Upd price list' in (OIS017), which starts 'Sales Price List. Update' (OIS310).
The mandatory selection fields 'Line valid from' and 'Line valid to' have the price list header's validity dates as default
value. The dates must be within the validity dates of the price list.
When creating new price list lines, the entered 'Line valid from' and 'Line valid to' dates are used as 'Valid from' and 'Valid
to' dates on the created price list lines.
When creating lines in a linked price list, the base price's validity dates are used if they are within the linked price list's
validity dates. If not, the linked price list's dates are used. This creates a date interval in the linked price list where
both the base price and the linked price are valid.
When selecting price list lines to update or delete, the specified dates in 'Line valid from' and 'Line valid to' indicate
the date range for which the price list lines will be updated or deleted. Price list lines with a 'Valid from' date within
the range are updated or deleted.
If the 'Function selection' field is set to1-'Create or Update', a new line is only created for an item if no line already
exists within the entered range.
