Can you please help explain how does period control affects the retirement of asset. I have this asset that uses period control 06- at the start of the year. Asset acquisition and capitalization date is January 2009, user retired this asset on May 2009. The output in ABAON shows only 3 line items and it posted to loss. Does period control affect this transaction? Also, what does it mean when period control is at the start of the year?
