Unable to delete parked document posted in 2013

Hello All,

We have parked one document in year 2013.  Now we would like to delete the parked document.

But while deleting the document we are getting an error message, stating that Periods closed for transaction: CO Through-postings from FI.

We have tried delete the same document in our quality client , it is not throwing any error (periods closed in Quality client also).

Can you please suggest me how to resolve this issue.

Thanks for your support  in advance.

Thanks

Prasad
