HI Carlos,
Since you archived PO, it is stored in archive physical drive not in SAP drive.
when u use me23n, the archived PO is picking from physical drive and it says "Already archived" message.
I'm sure there will be no table level entries for the archived documents
Go to SARA transaction - information system--> Archive Explorer - MM_EKKO and execute.
Check your PO is listed here.
So if you dont want to see your PO, then you need to De-activate information system
in SARA-Information System-->Customizing -
search infrastructure by Object name and use activate/deactivate icon -
A question i really need to know - Why you want to delete a particular PO, Archival process is not a small thing and usually it takes place as a MASS activity.
reg,
bhg
