AP Invoice Release Date field

Hi
I was trying to search the Invoice Release Date in the AP system for a Purchase Order but apparently Lawson does not store AP release date in the AP system as per Article 5353456 and 5413640.
Is there a corresponding Match date on the MA system or PO system that can be used as a substitute for the AP Invoice release date.
If so can you please let me know the table/field that stores match date and the relation between APINVOICE and the corresponding table in PO or MA system.
