Reset Deletion Indicator In SA

Hi,

Unable to reset the deletion indicator in SA, infact unable to move to change mode for SA, since the deletion indicator has been set for line item and header level, I am getting the following message,

Purchasing document XXXXX already archived

Message no. ME615

We have not done any archiving activity, Previously we used to reset the deletion indicator, but after EHP7 upgrade i am getting the above message,

Also gone through the BAPI_SAG_CHANGE , but unable to do so,

Kindly help me
