To allow work order/production order to be closed in targeted period instead of current system date.
At the same time, the journal for the variance should be created in the targeted period.
Where business operations are concerned, the production is completed on the last day of the previous month. Due to some reason, the user did not close the production order in the previous month. On the 1st day of the next month, then the user close production order. This causes variance to be posted to the wrong accounting period. It should be posted in the previous period instead of current period.
