Reversing a received item transaction

Good Morning

At the end of last month we had to Receive an item into inventory.   The accounts for April have been closed off and the transaction was recorded in Sundry Accruals.

We've just realised that the 'Received' transaction was made in error. 

So now I need to reverse it so the amount comes out of inventory stock and reverses the sundry accruals journal.

It will need to be done in the current month so that it doesn't affect last months reports.

Is there a way this can be done in purchasing?

Or will I have to make all the adjustments manually?

Thanks
