Defining Periods and Dates
If you wish to restrict the entry period or date on Purchase transactions you can use the following fields on the System tab to define specific ranges of periods and dates. Transactions can then only be entered within these ranges. These are referred to as the Open Ranges.
Leave these fields blank if you do not wish to set these restrictions.
Open From Period
The first period in the range.
Open To Period
The last period in the range.
Open From Date
The first date in the range.
Open To Date
The last date in the range.
Instead of defining specific dates or periods which then have to be maintained, you can ask the system to calculate the Open Ranges relative to the current date or period. To do this enter a positive or negative number in the following fields. For example, if the Open Period From Relative field is set to -3 and the Open Period To Relative field is set to +3, the Open Range is calculated as starting three periods before the current period and ending three periods after the current period. That is, a total of seven periods.
